Loop Selector Tracking - Mitsubishi MELSEC-Q series Programming Manual

(2) Make the following settings to perform tracking.
(Tracking is performed when the operation mode is switched to other than CAS, CSV or CCB.)
For 2-degree-of-freedom PID (S.2PID), set the following operation constant items to specify tracking.

Tracking bit (TRK)
Set value pattern (SVPTN)

Loop selector tracking

Tracking is performed under the following conditions.
• The operation mode is any of MAN, CMB, CMV and LCM and the tracking bit (TRK) is 1
• When the operation mode is any of AUT, CAS, CAB, CCB, CSV, LCA and LCC
The tracking bit (TRK) is 1 and BB1 of BB is 1

Example) When the S.SEL instruction uses the input value E1 and E1 uses the upper loop (loop 0) MV, the S.SEL
instruction's MV is trucked to loop 0's MV.
The setting that conducts Tracking is shown below.
