Installation of the “MODBUS” serial network
A network typically has a Master that “manages” communication by means of “commands” and Slaves that interpret
these commands.
GFX4-IRs are considered Slaves to the network master, which is usually a supervision terminal or a PLC.
They are positively identied by means of a node address (ID) set on the rotary switches (tens + ones).
GFX4-IRs have a ModBus serial (Serial 1) and optional Fieldbus (Serial 2) serial (see order code) with one of the
following protocols: ModBus, Probus, CANopen, DeviceNet, Ethernet.
The following procedures are indispensable for the Modbus protocol.
For the remaining protocols, see the specic Geex Probus, Geex CANopen, Geex DeviceNet and Geex Ethernet manuals.
GFX4-IR modules have the following default settings:
- node address = 0 (0 + 0)
- speed Serial 1 = 19200 bit/s
- parity Serial 1 = none
- speed Serial 2 = 19200 bit/s
- parity Serial 2 = none
You can install a maximum of 99 GFX4-IR modules in a serial network, with node address selectable from “01” to “99” in stan-
dard mode, or create a mixed GFX4-IR/ GFX4 / Geex network in Geex compatible mode in which each GFX4-IR or GFX4
identies 4 zones with sequential node address starting from the code set on the rotary switches.
In short, the valid rotary switch settings (tens + ones) are:
- (0 +0) = Autobaud Serial 1
- (B +0) = Autobaud Serial 2
- (A + 0) = Autonode Serial 1 for Geex slaves connected to GFX4-IR.

Communication error
If Modbus communication between GFX4-IR and Master node goes into timeout (settable in C.E.t parameter), you can
force an output power value (C.E.P parameter of each zone) and transmit the alarm state to a relay output (rL.x parameters).
