7. CIM 500, Modbus TCP setup

WARNING
Electric shock
Death or serious personal injury
- Connect CIM 500 only to SELV or SELV-E circuits.

7.1 Connecting the Ethernet cable

Use RJ45 plugs and an Ethernet cable. Connect the cable shield
to protective earth at both ends.
It is important to connect the cable shield to earth
through an earth clamp or to connect the cable shield
to earth in the connector.
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.

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.

Reserved, LED1 will be permanently red to indicate an
6-E
invalid configuration.
Reset to default setting
Note: The rotary switch must be set in this position for
F 20 seconds to reset to default setting. During this period
LED1 flashes red and green at the same time to indicate
that a reset will occur.
Every change of the rotary-switch setting while the
module is powered on will cause the module to
restart.

7.3 Setting the IP addresses

The CIM 500 Ethernet module is by default set to a fixed IP
address. You can change the IP address settings from the built in
webserver.
