Autobaud Serial 1" Sequence; Autonode Port 1" Sequence - gefran GFX4-IR Series Installation And Operation Manual

4.2 "autobauD serial 1"
Function
Adapt the serial communication speed and parity of the GFX4-
IR modules to the connected supervision terminal or PLC.
Green LED L1 "STATUS" mentioned in the procedure
can vary its behavior based on parameter Ld.1, which
is set to a default value of 16.
Procedure
1) Connect the serial cables for all modules on the network to
serial 1 and to the supervision terminal.
2) Set the rotary switch on the GFX4-IR modules to be
installed, or on all modules present in case of first installation,
to position "0+0".
3) Check that the green "STATUS" LEDs flash at high
frequency (10Hz).
4) The supervision terminal must transmit a series of generic
"MODBUS" read messages to the network.
5) The procedure is over when all of the green L1 "STATUS"
LEDs on the Geflex modules flash at a normal frequency
(2Hz) (if parameter 197 Ld.1 = 16 as default).
The new speed parameter is saved permanently in each
GFX4-IR; therefore, the "AUTOBAUD SERIAL 1" sequence
does not have to be run at subsequent power-ups.
When the rotary switch is turned, the green
"STATUS" LED stays on steadily for about 6 seconds,
after which it resumes normal operation and saves
the address.
