T 1: Time relay with transition-
sensing NO contact
* NOP 0 is required if the program is to be represented in LAD or CSF in the PG 635, PG 670, PG 675, PG 685, PG 695 or
PG 750 programmers. NOP 0 operations are automatically assigned when programming in LAD and CSF.
Note
The time tolerance is calculated as the sum of the time base and the maximum interval
between the SYNC synchronization block calls.
