• Writes clock data from D9025-D9028 to the clock
element after the END instruction is executed
OFF: No processing
ON: Set requested during the scan in which M9025 has changed from
off to on.
OFF: No error • Switched on by clock data (D9025 to D9028) error

ON: Display minute are indicated on the CPU front LED display.
OFF: No processing • Reads clock data to D9025-D9028 in BCD when
ON: Read request M9028 is on.
• Turn M9029 on in the sequence program to process
all data communication requests, which have been
received in the entire scan, during END process of
the scan.
