CR1000X(e) OS

v8.5.1

This download is for the CR1000X and CR1000Xe dataloggers. Execution of this download places the Operating System file(.obj) on your computer. It also updates the CRBasic Editor compiler and support files. 

Why Update?   New features and bug fixes. With this OS update it is recommended that you also update the Device Configuration Utility to the most recent version so that new datalogger features are available in the utility.  

Note/Warning: Campbell Scientific always recommends updating operating systems on site if possible. When remote updates are required, it is recommended that you implement the necessary precautions to handle unexpected OS upload complications. All datalogger settings should be retained when updated remotely. If you choose to roll back to a previous operating system, the datalogger settings will be reset to default.

v8.3.0July 28, 2025

  • (New Feature) Added a Basic JSON format to data streaming operations.

    • MQTTPublishTable() Output format 3 = BASICJSON
    • TableFile(), FTPClient(), HTTPPost(), HTTPPut() and, EmailRelay() Output format 36 = BASICJSON

  • (New Feature) Added a new setting FTPClientActivePort. This setting specifies the starting port the datalogger may use in Active FTP mode. It defines the lower bound of a block of 1000 consecutive TCP ports, which will be used for FTP data connections initiated by the datalogger. Each new data connection will use the next available port within this range.

    • Default value: 48000
    • Allowed range: 8000 to 48000
  • New Feature
    Added TableFieldNames() to the CRBasic Instruction list. Retrieves the name of a data table or one of its fields by index, enabling dynamic (at run time) identification of a DataTable and field names.
  • New Feature
    Added TableName.BytesPerRecord to return number of bytes in a DataTable record.
  • Major
    Refined the Operating System download process over MQTT.
  • Major
    Fixed an issue where heavy PPP traffic could overwhelm the system, causing the datalogger to drop outgoing packets. This sometimes led to missed LCP echo packets and unexpected connection closures, even when the link appeared healthy. Although the TCP layer would perform retries to prevent data loss, these retries significantly reduced data transfer rates.
  • Major
    Fixed watchdog resets caused by memory corruption due to TCP task queue buildup over slow data links, most commonly observed when RTMC projects were published on the datalogger.
  • Minor
    Fixed an issue where Implicit FTPS Active Mode incorrectly used reserved ports for data connections, leading to server rejections.
  • Minor
    A compile error is now triggered if FieldNames() contains a dot (.), and a warning is issued for other operator symbols; non-CRBasic-compliant field names will be deprecated and disallowed in a future update.
  • Minor
    The PakBus/TCP port (default 6785) is now restricted to PakBus traffic only; previously, if Telnet was enabled, the datalogger terminal could also be accessed on this port in addition to the standard Telnet port 23.
  • Minor
    When viewing the password settings via the CR1000KD, the value will now be displayed as '...' for security purposes.
  • Minor
    Modified GOES behavior for the TX325 to allow tables to be concatenated in a transmission.
  • Minor
    Improved handling of PPP flag bytes to ensure correct packet boundaries after a transmission error
  • Minor
    Lowered the TCP keepalive interval for FTPClient() command connections to prevent firewalls from closing them during long transfers. On slow links, the command connection can sit idle while data is still transferring, triggering idle timeouts.
  • Minor
    Temporarily provide access to MQTT v1 for units with a configured UID.
  • Minor
    Updated datalogger HTTP client to correctly handle absolute URLs in Location and Content-Location headers during redirection.
v8.2.1April 7, 2025
  • New Feature
    Added a self-hosted recovery webpage to the datalogger OS for uploading .obj and .web.obj.gz files to restore custom user interfaces. [ /recovery]
  • New Feature
    Added PING to the terminal commands.
  • New Feature
    MQTTPublishTable() will now send all unsent data ahead of OS update or program change, reducing potential data loss.
  • New Feature
    Added FieldClassify() to the CRBasic instruction set, providing additional support for MQTTPublishTable(). Refer to the CRBasic help for more information.
  • New Feature
    Added FieldOrigin() to the CRBasic instruction set, providing additional support for MQTTPublishTable(). Refer to the CRBasic help for more information.

  • (New Feature) Added the MQTT Auto-Publish Data option to the MQTT settings. This feature potentially simplifies the onboarding of existing datalogger applications to the Campbell Cloud without requiring program updates. Data Tables will automatically be published if the following conditions are met:

    • No Existing MQTTPublishTable(): The CRBasic program must not include any instances of the MQTTPublishTable() instruction.
    • Data Table with DataInterval(): The Data Table must utilize the DataInterval() instruction.
    • Data storage intervals less than 1 minute are excluded.
    • Data storage intervals between 1 minute and 10 minutes are published every 10 minutes.
    • Data storage intervals greater than 10 minutes are published at their defined interval.
  • New Feature
    Added an optional “Timeout” parameter to NetworkTimeProtocol().
    • Timeout = 0/Omitted: Default timeout is applied (75 seconds).
    • Timeout > 0: Acts as a timeout, specifying the maximum time the instruction will run before moving on.
    • Timeout < 0: The absolute value acts as a timeout and enables time servo mode. Time servo mode allows the datalogger to gradually adjust its clock to sync with the NTP server rather than making abrupt time changes. While this mode improves time tracking, accuracy is influenced by factors such as network latency and server variability.
      • Dependencies:
        • Execute the instruction every 2 to 5 minutes.
        • Set the "NTPMaxMSec" parameter to 1 second or less to maintain reliable synchronization.
  • Major
    Removed TLS cipher suites that do not support forward secrecy.
  • Major
    Fixed a memory leak in the MQTT process that occurred during reconnection events. This issue was observed when Cambell Cloud repeatedly rejected or dropped the communication link. This issue led to resource exhaustion over time, triggering the system to watchdog.
  • Major
    Fixed memory allocation issues in FTPClient() when using FTPS or SFTP put/get options. If a variable was used for the put/get option, insufficient memory was allocated. Conversely, negative values caused memory overallocation.
  • Major
    Improved session resumption and logging for FTPS.
  • Minor
    Fixed an issue were setting the "Timeout" parameters to 0 in client instruction may cause an infinite wait time. A value of 0 is now interpreted as the default timeout of 75 seconds.
  • Major
    Fixed a memory leak issues when Campbell Cloud certificates rotate.
  • Minor
    Fixed an issue where the CR1000X datalogger republished all data from the microSD card to the MQTT broker after an OS update.
  • Minor
    Enhanced MQTTPublish() to handle arrays. The payload parameter now accepts elements from a string array, and the return value can be stored in an array.
  • Minor
    Fixed an issue in sequential mode where a subroutine containing measurements, when called from a slow sequence, could cause the slow sequence to lock up due to incorrect handling of analog power control.
  • Minor
    RTMC projects published to a datalogger now take priority over default web pages by lowering the priority of the default web pages. This fix was originally implemented in a previous version, but the issue was reintroduced in version 8.0.
  • Minor
    Fixed an issue with MQTTPublishTable() that caused data to be published every other interval when the scan, data, and publish intervals were identical. Prior to the fix, no data was lost, as any missed data was included in the next successful publish.
  • Minor
    Fixed a formatted print buffer overwrite. This improved operations such as the data logger’s terminal output and logging IP Trace info.
  • Minor
    Fixed an API call issue that caused the TableDisplay page to not load.
  • Minor
    Fixed an issue where the MQTT command response incorrectly reported "File upload succeeded" when a file upload via MQTT command and control failed. The response now correctly states "File upload failed" on failure.
  • Minor
    Fixed Invalid JSON responses across several settings when requested via MQTT.
  • Minor
    Fixed a TLS memory allocation that caused an infinite reboot loop and over-allocated TLS memory when CRBasic functions requiring TLS were called within subroutines or functions.
  • Minor
    The "FileName" parameter in NewFile() can now accept a variable of type string.
  • Minor
    Fixed a CPI buss data shift issue.

  • New Feature
    Maximum number of ESS subsurface sensors increased from 10 to 20.
  • Major
    The MaxNumBytes (bytes allocated to buffering) now calculates memory for Dim variables correctly. Prior to this change, Dim variables allocated six times more memory than needed (same as Public variables). Large programs with many Dim variables may have generated OUT OF MEMORY errors in the compile results.
  • Major
    The datalogger no longer causes anomalies on VX1 when performing background calibrations tasks.
  • Minor
    ScanTime now updates correctly when a single scan is missed due to a low12V condition.

  • Minor
    CPI now works correctly with slow sequences in sequential mode. This resolves an issue that caused skipped scans and CDM frame errors with programs that have multiple scans and slow sequences.
  • Minor
    Table auto-allocation now works correctly in the case that both a slow (e.g., 1 day) table and a fast (e.g., 20 mS) table are both auto-allocated. The problem was the calculated fill time was less than the output interval of the slow table and this resulted in running out of memory.
  • Minor
    CPI Status now reports unused modules correctly, instead of reporting ‘Wait Config’.
  • Minor
    SW12() no longer forces sequential mode if the PipeLineMode() instruction is used.
  • Minor
    The read pointer in internal memory for CardOut() is now established correctly on program start up after a power cycle. The issue only occurred for data tables that were sized to 20 records or smaller and contained a CardOut() instruction. In this case, if power was lost during program run time data on the card could be corrupted.
  • Minor
    The skipped-scan counter now includes scans skipped due to insufficient power to the datalogger.
  • Minor

  • New Feature
    Added "press ESC ESC ESC ESC to close" when opening the Terminal Serial Talk Through mode.
  • New Feature
    Added a warning in the Status.CompileResult when a conflicting PakBus TCP route is found. This happens when there are two PakBus nodes with the same PakBus address on a network. While the conflict exists, PakBus polling will occur every 2 minutes instead of every 200 mSec to avoid unnecessary memory usage.
  • New Feature
    Added TTL (Time to Live) when monitoring DNS communication traffic.
  • New Feature
    Added Exclusive Option to the IPRoute() instruction.

    The function parameter in the TimerInput() instruction now resolves the erroneous compiler error that states "There are too may function digits specified, maximum is 14."
  • Major
    Settings.PPPDial now always keeps the RS232 port awake when the setting equals "PPP." The RS232 port would go into sleep mode disabling communications between the datalogger and the cell modem. This was present with datalogger and Raven XT combinations. Datalogger and RV50 combinations were not affected.
  • Major
    The ClockSet() instruction now avoids skipped records when the clock adjustments are less than one second.
  • Major
    The memory error that occurred when two PakBus/TCP Client connections were pointing to each other no longer occurs.

  • Minor
    Fixed an erroneous compile error when the index of an array is an expression with the first number equal to 0 (e.g., X(0+1), X(0+i)). Note that variable array indexes always start at 1, so if the expression used for the index returns 0, a runtime variable out of bounds warning is generated.
  • Minor
    You can now use pointers in ArrayLenVar parameter in the ArrayLength() instruction.
  • Minor
    You can now use pointers in TypeVar parameter in the TypeOf() instruction.

    The public declarations for the EssVariables() instruction now require a ten-element array for indexed OIDs.
  • Minor
    The SPIOpen() and I2COpen() instructions now configure the hardware at runtime.
  • Minor
    The reset parameter in the MaxRun() and MinRun() instructions now behave like AvgRun().
  • Minor
    String variables can now be referenced as (N,1) or (1). This avoids a variable out of bounds error at run time.
  • Minor
    Constant declarations now allow a Const to be equal value in the settings table. Example Const A = Settings.SerialNumber.
  • Minor
    The Timer() instruction now uses the system time instead of the clock so the timer is independent of the clock being adjusted.
  • Minor
    The SDI12Recorder() instruction now accepts type Double for the destination variable.
  • Minor
    The SDI12Recorder() instruction timeout now ignores noise spikes while waiting for the sensor to be ready.

  • Minor
    The PakBus verify interval advertised in the 'Hello Exchange' is now equal to the verify interval setting rather than the setting / 2.5.
  • Minor
    DNS will now attempt to first resolve IPv6 then IPv4.
  • Minor
    The default DNS server is now listed last. The specified DNS address is listed first.
  • Minor
    TimeUntilTransmit is no longer allowed outside a Scan/NextScan.
  • Major
    SWVX now works outside of the main scan when setting VX1 to 5 V.
  • Minor
    Settings.PPPInterface now disables auto baud functionality. A specific baud rate must be set.
v1.02December 21, 2017
  • IMPORTANT: Resolved an issue with PPP connections that timed out or were closed with the PPPClose() instruction and then reopened with the PPPOpen() instruction. This type of connection is often used with cellular modems. A flag that tells the datalogger that the network is online was not being reset correctly, resulting in an unresponsive PPP network interface.
  • Fixed terminal W mode so the terminal will not exit when receiving a character on another comport unless CR (carriage return), or ESC (escape) is received.
  • Fixed terminal mode monitoring via W command when a new connection is made. The datalogger now ignores a new connection unless it is via PakBus or Telnet. The datalogger recognizes a connection when a CR (carriage return) or ESC (escape) character is received from the new connection.
  • Fixed Tablename.Fieldname when sampled into another table when a record did not exist in the source table. The operation now returns a NAN when this condition occurs.
  • Fixed GoesTable() to output commas instead of spaces.
  • Fixed background calibrations that were failing when using SequentialMode.
v1.01October 18, 2017
  • Changed the default username and password used by the datalogger FTP server. The new username and password are now both NULL. This change requires the user to set their own username and password (both required) in order to use the datalogger FTP server. Neither the username or the password can be blank. This change was made to better secure the datalogger FTP server against malicious attacks. This change does not affect the FTPClient() instruction.
  • Changed reset tables via the keyboard display to require first level security.
  • Changed terminal sniff on Ethernet to show the entire Ethernet packet instead of just the first 54 bytes.
  • ESSVariables(): enhanced the pre-compiler to flag an error if variables are declared as the wrong type or wrong dimensions.
  • Various fixes and adjustments made to make the PC CRBasic pre-compiler more robust and more verbose with warnings and error messages.
  • Fixed various settings of type Boolean (BOOL4 and BOOL) that were not being set correctly via the SetSetting() instruction.
  • Fixed EmailRelay() if the ServerResponse parameter is not a variable of type STRING.
  • Fixed TableName.FieldName() when FieldName is a timestamp passed into a function as type string. The logger now allocates enough memory for the string instead of just the 8 bytes of the time stamp.
  • Fixed NetworkTimeProtcol() which could have had a 500 msec offset error.
  • Fixed setting a BOOLEAN in a Constant Table. Prior to this change, the timestamp would increment at every scan regardless of whether the table was updated or not.
  • Fixed the keyboard display when displaying RS232Power to show correctly and not a value of 255 when set to True.
  • Fixed the keyboard display when displaying floating point numbers greater than 2.0465E9.
