I have a PLC5/40E PLC. It has a RIO network already connected to it. I want to add a Powerflex 700 with a 20-comm-r communications card to this network.
There are 13 existing nodes on this RIO network.
I want to send and receive the logic/status and speed reference/feedback signals.
Will ½ size give me the above or do I need to do extra messaging?
Is the reference/feedback 16 or 32 bit on the pf700 drives? If they are 32 bit, whats the best way of handling it in the PLC5.
I want to control the pump speed based on pressure. I was thinking of setting up a PID controller in the PLC5 to handle this. There are already 12 pid block setup in the PLC. They are using the PD structure.
Whats the difference between the PD and PID structure or does it matter which one select.
Do I need to do anything special in the PLC5 that I would not have come across in the new controllers or wouldn’t be aware of having only used the newer controllers.
I wont get much time to set this up offline either. I will have to do it in about a 3 or 4 hour window so I need to be very comfortable with the offline solution I come with when I go to implement it.
I have used controllogix and compaclogix PLC’s before but my knowledge on PLC5 is limited. I have used devicenet, ethernet, profibus and modbus comms before, but not RIO.
Any advice on how to implement the above on a PLC5 platform would be appreciated.
