Defaults menu.

Echo relay to slave
The Echo relay to slave attribute sends the energize or de-energize relay
commands to the DL50 slave addressed in the Send message to slave
number attribute. These commands are sent in addition to any specified
message text.
After this attribute sends a relay command to the slave, the slave relay will
not de-energize until another message is sent to the slave that meets both of
the following conditions:
•
Energize relay is set to No (to de-energize the relay)
•
Echo relay to slave is set to Yes (to send a de-energize command to the
slave display)
Acceptable values for this attribute include:
For DL10 or DL20 For DL50

the Echo relay to slave attribute is always set to No when you create a
message unless you have specified a Yes on the Message Attribute Defaults
menu.

only. Do not use it for control.
