3.5.3 Data exchanged through Fieldbus
The following table details the data exchanged through the Fieldbus communication:
WARNING! The system is in alarm if the "control unit status" byte of the "System configuration and
status" module PS2v6 or PS2v4 is different from "0xFF".

3.6 Modbus communication
3.6.1 Modbus support
The Modbus communication uses the Ethernet port (Modbus TCP) and consequently is only available for ISC-B01
and ISC-02 control units.
3.6.2 Modbus communication enabling
In the Inxpect Safety application, click on
Settings
>
Modbus Parameters
>
ON
to enable the feature.
Within the Ethernet network, the control unit acts like a server. The client must send requests to the IP address
of the server on the Modbus listening port (default port is 502).
