4.1.2 Modbus
2259
The device offers the following Modbus functions:

Provision of the functions of a Modbus TCP Slave

2 port switch for access to the Modbus interface (X21/X22)

Gateway for transmission of the process and parameter data between the connected IO-Link
devices and the higher-level Modbus controller
>
4.1.3 Internet of Things (IoT)
8355
The device has an Ethernet port (X23) for Internet-of-Things applications. The interface allows
separate access from IT networks to parameters, process and monitoring data of the IO-Link master
and the connected IO-Link devices. Different protocols (e.g. TCP/IP JSON) are supported.
