The use of PROFIBUS plugs is recommended for wiring DP/FMS networks. These plugs include special functionalities that allow for reliable operation and fast, robust assembly. These functionalities may comprise:
•In-built line termination resistors that can be switched on or off.
•Fast, robust connection of signal wires
•Large-surface laying of cable shield
•Insertions for incoming and outgoing cables
•In-built, special inductances for bit rates higher than 1.5 Mbit/s
•Cable outlet shut down when the termination resistor is switched on
•Additional plug for connecting diagnostic or programming tools
Terminals may also be used to connect the stations (devices).
Three alternative ways of connecting with RS-485 transmission using the IP65/67 protection class have been provided:
•M12 circular connectors according to IEC 947-5-2
•HAN-BRID connectors according to DESINA recommendation
•Siemens hybrid connectors
The HAN-Brid connector system also includes a version for transmitting data via FOC lines and a 24 Volt operating voltage for peripheral devices via copper cable in one, common hybrid cable.
