Setting COMMUNICATION SETUP*(Only for models with communication)
One or more RGU-10C instruments 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 instrument, 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 instrument is connected to one single series line (RS-485), it is necessary to assign 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 equipment 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.
On entering setting mode a screen is displayed showing that the equipment has entered communication setting
mode.
To enter setting mode the PROG button must be pressed
Peripheral number
The display shows PERI and the peripheral number on the upper left of the screen.
To write or change the number of the peripheral repeatedly press the td button, increasing the value of the digit which
is in the upper left corner.
When the required value is on the screen, it is entered and the display moves on to the next menu by pressing PROG
button, to allow the remaining values to be changed.
The peripheral number varies between 1 and 99.
To access COMMUNICATIONS SETUP the PROG button has to be pressed to enter setting mode.
