Hi,
In one of my applications there are are ESD valves with limit switches. These limit switches will be connected to ABB DCS. These inputs will be line monitored since they are ESD valves. I have following questions:
1. What is meant by monitored inputs? How are they defined?
2. What kind of hardware arrangement is required on field instrument side?
3. Is any special software required on DCS side for this?
Thanks in advance.
