ControlLogix RMPS / PIDE Instruction Example.

How to use the Ramp/Soak (RMPS) Instruction with the PIDE block?
The RSLogix 5000 v13 sample file attached below contains a very basic application with a RMPS and PIDE. A process simulator Task is also included for simulation purposes.
  • While in Manual mode the user program directly controls the instruction's Out. The CurrentSegProg, SoakTimeProg and OutProg inputs are transferred to the CurrentSeg, SoakTimeLeft and Out outputs.
  • When instruction is placed in auto mode, the ramp/soak functions resumes with the values last input from the user program.
  • CurrentSegProg and SoakTimeProg are not transferred if they are invalid. This will explain a SoakTimeLeft at zero after a manual to auto transition and SoakTimeProg was zero.
More information can be found in RSLogix 5000 software Instruction Help file or in the Logix5000 Controllers Process Control and Drives Instructions  manual.
