Using The Umc100.3 In A Modbus Rtu Network; Integration With The Eds File - ABB UMC100.3 Manual

Integration with the EDS File

Besides the physical connection of a device to a DeviceNet line, the integration and engineering of the devices in the DeviceNet
master is necessary. An electronic data sheet is provided for the UMC100.3 for that purpose. In the DeviceNet world these electro-
nic data sheets are called EDS files. Within these files all the properties relevant for operating the slave are described (e.g. suppor-
ted baud rates, parameters, ...).
Configuration of the control and protection parameters of the UMC100.3 can be carried out using the EDS file. For
creating a customer-specific application the DTM softare tool can be used!
ESD file for UMC100.3 with DNP31 can be obtained from ABB's web site : http://www.abb.com

Using the UMC100.3 in a MODBUS RTU Network

The MODICON Modbus® RTU protocol is a widely used network protocol based on the RS485 physical layer. It is provided in many
PLCs that do not offer any other fieldbus. To integrate the UMC100.3 into a Modbus network, use the MRP31. The diagram below
shows the sketch of a Modbus line with two MRP31, two UMC100s and available accessories. More details are available in the tech-
nical manual of MRP31.

Modbus Line with MRP31 and UMC100.3. Use standard Modbus cable for wiring
There are no device description files defined by the Modbus standard.
Therefore we recommend that you parameterize the UMC100.3 either using the UMC100-PAN or using a laptop
with the PBDTM software tool.
