5.4.- CONFIGURATION THE COMMUNICATION SETUP
Note: Only for RGU-10C models.
One or more RGU-10C devices may be connected to a computer or PLC in order to automate a
production process or an energy control system. As well as the usual operation of each device,
this system may centralize data at one single point; for this reason the RGU-10C has an RS-
485 communication output.
If more than one device is connected to one single series line ( RS-485 ), it is necessary to as-
sign to each a number or address (from 1 to 99) so that the central computer or PLC sends the
appropriate requests to these addresses for each peripheral.
From communication SETUP, the
RGU-10C
’s communication parameters may be displayed
and/or changed; this may match these parameters to the requirements of the system topologies
and/or applications.
The device does not save the setting changes until all of the setting has been entered using the
PROG button. When it detects that the keyboard has been inactive for a certain time it displays
“
EXIt”
and the setting menu is exited it without saving the changes.
To access communications SETUP press the PROG key.
On entering setting mode a screen is displayed showing that the device has entered commu-
nication setting mode.
