PROFIBUS Module (RMC150)

The PROFIBUS module for the RMC150 provides PROFIBUS communications. Notice that since the RMC150E CPU has built-in Ethernet, it is possible to communicate via Ethernet and PROFIBUS simultaneously.

For details on setting up and using PROFIBUS, see the PROFIBUS Overview topic.

Features

PROFIBUS-DP
1 Comm Status LED
Standard PROFIBUS-DP DB-9 Connector

Part Number

The part number of the PROFIBUS module is -PROFI. The PROFIBUS module fits only in the left-most slot of the RMC backplane.

For example, RMC150E-S1-PROFI is an RMC150E with an SSI module and a PROFIBUS module. RMC150E-S3-Q1-PROFI is an RMC150E with three SSI modules, one Quadrature module, and a PROFIBUS module.

LEDS

Comm Status

State	Description
Steady Off	No PROFIBUS connection is established. See the Troubleshooting PROFIBUS topic for possible reasons.
Steady Green	A PROFIBUS connection is established.

Note:
These are the only two LED states of the NET LED, but it is possible to have the Net LED flashing or flickering green, which indicates that the RMC75P is going on- and off-line on the PROFIBUS channel and generally indicates a network or configuration problem.
