Chapter 7 Logic Functions
Semantics of selections:
• Last-state = hold the output in its last state on communication loss
• De-energize = put output into de-energized or normal state on
communication loss
• Resume = restore output control when communication recovers
• Freeze = maintain state of output when communication recovers until one
of the following occurs:
– Logic controller enters program mode
– Power cycle to the power monitor
– Change the parameter value to ‘resume’
• Local Control = Revert to local power monitor control (pulsed or
setpoint) on communication loss. When communication recovers and
connection is re-established, output control by the connection host
resumes.
Status
Relay and KYZ output status is reported by the state of the following Boolean
tags, found in the Status.DiscreteIO
table. For each tag, 0 = False, 1 = True.
KYZ _Output_Energized
KYZ_Forced_On
KYZ_Forced_Off
Relay_1_Output_Energized
Relay_1_Forced_On
Relay_1_Forced_Off
Relay_2_Output_Energized
Relay_2_Forced_On
Relay_2_Forced_Off
Relay_3_Output_Energized
Relay_3_Forced_On
Relay_3_Forced_Off
Commands
The following command parameters are found in the
Command.System_Registers
table. These commands are not permitted if an
Exclusive Owner connection has been established with a Logix controller.
