10.7.2.11 Retentive SET Coil
Retentive SET and RESET coils are similar to SET and RESET coils, but they are retained
across power failure or when the PLC transitions from to Run mode. A retentive SET coil
sets a discrete reference ON if the coil receives power flow. The reference remains ON
until reset by a retentive RESET coil.
10.7.2.12 Retentive RESET Coil
This coil sets a discrete reference OFF if it receives power flow. The reference remains
OFF until set by a retentive SET coil. The state of this coil is retained across power failure
or when the PLC transitions from Stop to Run mode.
