Hardware required for network connection:

CIM 500
Product number: 98301408

The CIM500 interface offers easy integration into both new and existing systems, as the Modbus TCP protocol is a standard protocol supported by numerous control and automation systems.
With a rotary switch, you can easily change the protocol to PROFINET IO, Bacnet Ip and Ethernet IP.
An integrated webserver allows easy Ethernet parameter changes to configure the CIM500 to the wider system.
