Description
This relay enables the Programmable Controller CPU to change the communication state of the SECS/
GEM communication software.
When this setting is enabled, turn the trigger ON to configure an ENABLED state and turn the trigger
OFF to configure a DISABLED state.
An ENABLED/DISABLED trigger results when the ENABLED/DISABLED relay was held for the
configured time.
If the "Not Monitored" checkbox is selected, ENABLED/DISABLED trigger processing is carried out
without hold monitoring.
Description
Select whether communication establishment is to be attempted automatically by the SECS/GEM
communication software or upon request from the programmable controller CPU.
• AUTO: SECS/GEM communication software attempts to establish communication automatically.
• SEMI-AUTO: Attempted automatically by the SECS/GEM communication software only when the
Communication establishment request relay is ON.
• MANUAL: Attempts to establish communication upon request from the programmable controller
CPU. Determine the value of the communication state notification register by the programmable
controller CPU and switch ON the communication establishment relay defined below.
Configure the relay to notify the SECS/GEM communication software about the communication
establish attempt when SEMI-AUTO/MANUAL was selected.
When this relay is switched ON, the SECS/GEM communication software attempts to establish
communication.
A communication establishment request trigger results when the communication establishment request
