SLC500 temperature control
SLC500 temperature control
(OP)
We want to control temperature with an SLC 5/03 controller and a SLC500 NT4 thermocouple input. Is there any good software available to help with the setup of something like this and a PID loop?
Thanks
Thanks





RE: SLC500 temperature control
Tuning a temperature loop is either dead simple or a nightmare - the latter usually arises from long transport delays in the process between a controller demand change and the process variable at the sensor responding. Good control using PID in a loop with a long transport delay is tricky - often feed-forward yields better results.
You might want to check out the Ziegler Nichols tuning method if your process is amenable to it. This link gives a fair explanation, and any control engineering text will have this and a lot more detail.
