PID Setup Dialogs: ( This version of the program was captured/saved while active, thus some values are shown that normally are blank but are being displayed here as the PID ramps up) SetPoint: DRY_TEMP_SET_HMI, read straight from the HMI and moved into PID_TEMP.SP. This channel configured for, range = 1- 4-20Ma, dataFormat = 2, PID. Process Variable: ( in this case the average of 2 thermocouples) The thermocouple channels are configured for PID data format, type j, deg f.Ĭontrol Variable: directly to analog out channel, Local:7:O.Ch1Data. Perhaps, this wasn’t the best way (I didn’t want to re-scale some things used for other purposes) but here is how I set up PID_TEMP.

The 1769 analog out modules don’t have the jiffy configuration tool ( or as many options when configured via “data monitor” ) and as such I couldn’t configure the output as 0-100 = 4-20Ma If RS5000 is used for Control Logix PLCs and modules or the 1769 modules are used with MicroLogix and RSLogix 500, things WILL be different.Īs noted by tomalbright, there are substantial differences between compact logix ( micro logix ) and control logix modules. The following was my version applicable to a compact logix 1769-元1 PLC with 1769 modules using RSLogix 5000 (v15).
