Does the Yokogawa CS3000 have an option to detect when the valve’s response time exceeds a certain number of seconds, causing the valve to stop moving?

I don’t know if such an option for detecting the valve’s response time exists in Yokogawa’s device function blocks. In other words, once a command is sent to the valve, if no feedback is received after a certain number of seconds (set by the user), then the command to open the valve is no longer sent, or the valve is automatically commanded to close

There seem to be similar function blocks, but I haven’t used them. You can check the list of function blocks; however, it’s possible to achieve this even without manual configuration

The simplest way to implement this is as follows: if the SIO module is used to control the valve, an alarm PERR indicating that the valve is not in the correct position is triggered when PV is not equal to MV. After this alarm persists for several seconds (as determined by a timer), the valve’s output is set to 0. Regarding what you mentioned about stopping output, the solenoid valve has 2 positions.
