Interface
The Profibus-DP communication interface allows slave connection to an industrial Profibus network.
Profibus-DP allows industrial devices to be controlled over an open network architecture enabling
device connection at various locations in the field. This “Fieldbus” technology reduces
hardwiring/cabling & provides ease of installation. It can interface with many devices such as limit
switches, sensors, directional valves, motor starters, bar code readers, process sensors, frequency
drives, etc. The network can have up to 126 nodes. Its maximum communication baud rate is 12M
baud and its minimum baud rate is 9.6K baud.
Node addressing is selectable using the address selection switches. Baud rate is auto detected from
the master and no user setup is required. Module & Network status LED’s provide network
diagnostics. Maximum I/O data is 244 input bytes & 244 output bytes. FEC Inputs match the discrete
input layout. FEC Output location is programmed using the DSP User Console Software.
Note: The Profibus interface is implemented according to the Profibus-DP EN 50 170 (DIN 19245
Part 1) specification.
FEC integrates the Profibus-DP board manufactured by HMS Fieldbus Systems AB into the Multi-
Unit modular I/O board. For further technical information on the Profibus interface go to the HMS
website. (www.hms.se)
