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
I/O Mode (32 regs)
I/O Mode (16 regs)
I/O Mode (8 regs)
I/O Mode (4 regs)
Basic
Basic+
Enhanced
Enhanced+
I/O Mode (32 regs)
I/O Mode (16 regs)
I/O Mode (8 regs)
I/O Mode (4 regs)
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
