SDM-CD8S 8 Channel Solid State DC Control Module

2. The sequence continues running as if nothing happened until the next

occurrence of the sync interval (synced to the current clock) and then
restarts.

3. Ignore the change in the clock, keep the current count and index

proceeding as if nothing happened.

When the TimedControl instruction is used within the program (i.e, after
BeginProg) to reset or change the sequence this option is used to set what
happens between the time the instruction is executed and the sync interval
occurs. Only option codes 1 and 2 are valid:

1. The instruction behaves as if it were just started after compile and the

input to the SDMCD16 goes to the default value.

2. The sequence continues running as if nothing happened until the next

occurrence of the sync interval and then restarts.
