Internal relay (M)
Device intended to be used as an auxiliary relay inside the CPU module. All internal relays are turned OFF by the following 
operation.
 • CPU module power OFF
ON
 • Reset
 • Latch clear
Latch relay (L)
Auxiliary relay that can latch (backup by battery) in the CPU module. Computation results (ON/OFF information) are latched 
even when performing the following operations.
 • CPU module power OFF
ON
 • Reset
Link relay (B)
Device intended to be used as a CPU side device when refreshing bit data between CPU module and network module.
Refreshing network module that uses link relay (B)
Sends/receives data mutually between network module link relays (LB) and link relay (B) in the CPU module. Set refresh 
range by parameters of the network module. Link relays not used for refresh can be used for other purposes.
Annunciator (F)
Internal relay used for program for detecting equipment errors/faults created by the user. When the annunciator (F) is turned 
ON, SM62 (Annunciator (F) Detection) turns ON, and the number of annunciator devices that are ON and their numbers are 
stored from SD62 (Annunciator (F) Detection No.) to SD79 (Annunciator (F) Detection No. Table).
