Hello, From manual : Complete Restart/Restart The PID_CP function block has an initialization routine that is run through when the input parameter COM_RST = TRUE is set. Ramp soak (RMP_SOAK) When the ramp soak is activated, the time slices DB_NBR PI[0 to NBR_PTS].TMV are totalled between the coordinates and indicated at the total time T_TM and total time remaining RT_TM outputs. If PI[n].TMV is modified on-line or if TM_CONT and TM_SNBR are set, the total time and total time remaining of the ramp soak also change. Since the calculation of T_TM and RS_TM greatly increases the processing time of the RMP_SOAK function when a large number of time slices are involved, this calculation is only performed after a complete restart or when TUPDT_ON = TRUE is set. Integral action (INT) When the controller starts up, the integrator is set to the initialization value I_ITLVAL and the integral action is output at the LMN_I output. When it is called by a cyclic interrupt, it starts at this value. All other outputs are set to their default values. Regards, Marcjan |
