Can a pressure sensor give two system signals at the same time? It is a 5 meter sensor and a 100 meter sensor. There's only one PLC and one converter. But there are two sets of control loops in the PLC that require sensors to give signals separately. Now change to a 100 meter sensor for the signal. Can the parallel signal terminal be controlled? Is PLC still able to collect signals?
For systems that employ voltage ring transmission, this can only be done, and it is not possible for systems using current loop transmission.No matter what system is adopted, it is very dangerous for a signal to be uploaded to two receivers at the same time. It is generally advised not to adopt this method
100 meters away from the data back is not allowed, parallel more inaccurate..One PLC receives data. Another PLC reads the received data in a communication mode.
To see what is your signal, if the signal is the voltage you can try, but do not suggest that you do, after all, are generally two PLC signals from the switching power supply different from the possibility of a burning point. Current signals do not want to, parallel certainly not, and generally PLC, AI points have matching internal resistance, and if the series resistance is too large, your instrument should not be brought up.
