6 Communication

The station address on the RMC75P must match the station address as expected by

the master. Step 3 explains how to set the station address in the master.
Example

The station address is:

(0 x 10) + (3 x 1) = 3

RMC150E

a. In RMCTools, go online with the RMC.
b. In the Project Pane, expand the Modules folder and double-click the

PROFIBUS module.

c. On the PROFIBUS page, enter the desired station address. Use any station

address between 1 and 125. Since the station address 1 is normally used

for the master, Delta recommends not setting the address to 1. The value

126 is the default address and indicates that a station address has not yet

been assigned.

d. Click OK. The change will automatically be downloaded to the RMC.

2. Determine the Appropriate GSD Configuration Module

A GSD file is a device description file used to inform the PROFIBUS master how to

communicate with the device. The master requires a GSD file from each device in

the network. The RMC's GSD files are is installed by the RMCTools software package

in the RMCTools folder. The GSD file is also available from Delta's website

•

RMC75P: DELT07E1.GSD

•

RMC150E: DELT0AC6.GSD

The GSD file contains several configuration module entries. When adding an RMC to

a PROFIBUS network (Step 3), you will need to select exactly one of these

configuration modules. Each of these modules is assigned a title, which is often

referred to by PROFIBUS configuration software as an Order Number.
To determine the correct GSD order number, first determine the operation mode.

The following operation modes are available on the RMCs:

RMC75P

RMC150E PROFIBUS

If you do not know the difference between these modes or have not yet determined

which is right for your application, please read the PROFIBUS Overview topic. Most

users prefer the I/O modes.
Delta has found several cases where the GSD file is not supported correctly or

manual setup is otherwise required. In these cases, you will need to manually set
