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.

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.
7.4. General
7.4.1. Control Output
The Control Output is the control signal voltage supplied by the RMC to drive the amplifier,
valve, or drive for the system to be controlled. It is an analog output with a voltage range of -
10 V to + 10 V. To convert the Control Output to current, use Delta's VC2124
voltage-to-
current converter.
The modules listed below have a Control Output. The Control Output is labeled Drive or Drv
on the RMC150 modules.
