Process Control Instruction 349Runtime ErrorsError code 0036 appears in the status file when a PID instruction runtimeerror occurs. Code 0036 covers the following PID error conditions, eachof which has been assigned a unique single byte code value that appearsin the MSB of the second word of the control block. The error code is alsodisplayed on the PID Setup Screen in RSLogix 500/RSLogix Micro.Error Code Description of Error Condition or Conditions Corrective Action11H1.
