Hello,
Can anyone tell me how can we determine the spare available adrressing in Proficy ME PLC? I looked up on the Variable tab and its not giving much clue.

But as you know Addresses are not needed in the RX3i PAC platform. :)
Just use Variable "Names" and let the software handle addressing needs.
Some call this "Symbolics".

This is using PME 7.50 SIM6
YMMV
A more detailed question may bring a more detailed answer from someone.

I also have an issue with the PID controller for the control valve. We had an instance where the controller was in auto mode and controlling the fine and all of a sudden it jumped to 100% output.
What would be a likely cause of this? I had a look at the trends and could not see an obvious thing that can tricker this.
The pid is from proficy machine ME

What do you need to do make it happen again? Whatever the answer is will point you in the correct direction to look.

If the operator needed to put the PID back into Auto, who or what can take it out of Auto?
The PID Function an a GEIP PAC/PLC has this controlled by a bit in logic. Look up that bit and see who/what can change it.

Hello All,
Can anyone tell me if there is a FBD in Proficy ME that can do selection between two analog inputs where the output is determined by a switch. For instance if I have IN1 and IN2 and and the S is the switch to select IN2. I have a situation where it is a PID loop that controls the valve. However when in normal operation ie. Auto the valve should be fully closed (0%) and if the temeperature goes above the set SP it should open to regulate to bring down the temperature below the SP and should bring the valve to fully closed again when the temp comes below SP. I know in DCS there are FB that can switch to transfer the 0 output to the valve however I looked at the FDB of the Proficy ME and its not giving much information. Is there a way to achive this or should I start looking at developing a UFBD for this operation.
Thanks in advance for your help.
Regards.
