I need to add a 4th sensor that requires excitation to a CR1000 but all 3 VX ports are already being used. VX3 is a CS107 and I need to add another CS107. Can both share VX3 without affecting the operation of either sensor (there would be 2 successive Therm107 calls, 1 to each sensor)?
a VX channel can supply tens of 107 sensors, perhaps even more than those that the wires enter the terminal!
It is possible to use one instruction for each 107. If n 107 are on successive channels, even a single instruction, declaring n repetitions. Obviously without increasing the Vx channel, which is always the same.
