(5) Special relays and special registers for reading/writing clock data
The section explains the special relays and special registers used for setting data
and reading clock data for clock operation.
(a) Special relays used for the clock function
*1
Can only be used with the Q3ACPU and Q4ACPU.

Name
Description
SM210
Clock data set request
• Writes clock data to the special registers (SD210 to
SD213) and performs clock operation.
• Writes the clock data stored in SD210 to SD213 to the
clock elements after execution of the END instruction in
the scan in which SM210 turns from OFF to ON.
SM211
Clock data error
• Used to determine whether or not there are any errors
when the clock data is set.
• Turns ON if any data is not a BCD cord.
SM212
*1
Clock data display
• Displays clock data on the LED indicator on the front
panel of a CPU module.
• When SM212 is ON, the clock data is displayed on the
LED indicator on the front panel of the CPU module.
SM213
Clock data read request
• Reads the clock data stored in special registers SD210
to SD213.
• When SM213 is ON, the clock data is read to SD210 to
SD213 after execution of the END instruction.
