7. Modbus TCP, CIM 500 setup
7.1 Connecting the Ethernet cable
RJ45 plugs and Ethernet cable must be used. The cable shield
must be connected to protective earth at both ends.
The CIM 500 is designed for flexible network installation; the
built-in two port switch makes it possible to daisy chain from
product to product without the need of additional Ethernet
switches. The last product in the chain is only connected to one of
the Ethernet ports. Each Ethernet port has its own MAC address.

Fig. 18 Example of Ethernet connection
7.2 Setting the Industrial Ethernet protocol
The CIM 500 Ethernet module has a rotary switch for selection of
the Industrial Ethernet protocol. See fig. 19.
Fig. 19 Selecting the Industrial Ethernet protocol
7.3 Setting the IP addresses
The CIM 500 Ethernet module is default set up to a fixed IP
address. It is possible to change the IP address settings from the
built-in web server.
Warning
The CIM 500 must only be connected to SELV or
SELV-E circuits.
Note
It is important to connect cable shield to earth
through earth clamp or to connect cable shield to
earth in the connector.

Reset to factory default
Note: The rotary switch has to be set in this position for
20 seconds to reset to factory default. During this period
LED1 will be flashing red and green at the same time to
indicate reset will occur.
Note
Every change of the rotary switch setting, when
the module is powered on, will cause the module
to restart.
