4.1.5 Address assignment
When the measuring system is delivered, its MAC address is
stored by default. This is noted on the nameplate of the
device, eg “00-03-12-04-00-60”, and can not be changed.
The name for the device type assigned by TR-Electronic is
TR Rotative Safety and can not be changed.
Before an IO device can be addressed by an IO controller, it
must have a device name, so that an IP address can be
assigned to the device. If necessary, the IO controller assigns
IP addresses to the IO devices according to their device
names during startup.
The measuring system has no device name stored when
delivered and after a reset. Only after the assignment of a
device name with the engineering tool is the measuring
system addressable for an IO controller, e.g. for the
transmission of configuration data (e.g. the IP address) during
start-up or for useful data exchange in cyclical operation.
The name is assigned before commissioning via the
engineering tool.
The measuring system has no IP address stored when
delivered and after a reset.
Default value: “0.0.0.0”
The measuring system has no subnet mask stored when
delivered and after a reset.
Default value: “0.0.0.0”
Procedure for assignment of device name and address for an IO device
● Define device name, IP address and subnet mask. Depending on the configuration of the IO
controller, this may be defined automatically.
● Device name is assigned to an IO device (MAC address)
– Transfer device name to the device
● Upload configuration to the IO controller
● IO controller assigns the IP addresses to the device names during start-up. The assignment of the
IP address can also be switched off. In this case the existing IP address in the IO device is used.
