Does anyone know of any software or formula to convert APACS PID tuning parameters to PCS 7?

Here are the conversions for the PCS 7 Standard CNTRL_PID block.  The APL PidConL would be similar (but IO Names different).  PidConR uses the same algorithm as APACS PID Controller so conversion factor should only be time units (seconds to/from minutes).

  1. PCS 7 TV (Differentl Time sec)/60.0 = APACS TD (Time-Dirivative minutes)
  2. PCS 7 TV (Differentl Time sec)/PCS 7 TM_LAG (Lag Time Constant sec) = APACS DG (Derivative Gain)
  3. PCS 7 TN (Reset Time Sec)/ 60.0 = APACS TI (Time Intergal Minutes)
  4. PCS 7 Gain (Proportional Gain) = APACS PG (Porportional Gain)
