1 One identifier bit for each logical module (adapter and each slot use two identifier bits). The bits
set indicate a module fault. For example down below.
Example: If the modules in slot 3 and 6 are faulty, byte 13 to 15 will look like this.

6.3 Configuration differences between 1794-APB and 3170-PDP.
There are two things that must be taken in consideration when replacing the AB
adapter with HMS adapter. These items are further described in this document.
1
PSFT0882.GSD file:
The 1794-APB has a Rockwell GSD file with a Rockwell "PROFIBUS Ident
Number" (stating Rockwell as manufactor among other things).
The 3170-PDP has a PSFT0882.GSD file with a "PROFIBUS Ident Number"
(stating PROSOFT TECHNOLOGY, INC. as manufacturer among other
things).
For a new customer this does not make any difference, he just use the
PSFT0882.GSD file instead of the old Rockwell GSD file when installing the
unit.
For a customer already using 1794-APB and need a replacement unit, this
will generate some extra work for that user. The adapter is fully replaceable,
but if a replacement of the adapter is done, the PROFIBUS Master is still
configured with the Rockwell GSD file. The 3170-PDP only responds to the
PSFT0882.GSD file, which means that the Rockwell GSD file must also be
replaced, otherwise network communication will not start.
You must start up the PROFIBUS Configurator and replace the Rockwell
GSD file with the PSFT0882.GSD file.

User parameter data:
One extra byte of user parameter data has to be added to the
parameterization string. This extra byte is needed for the 12Mbit ASIC on
board. The user has to add this extra byte in the first position of the user
parameter data string. An example of the adapter configured in Full Format
for the different adapters are shown below. Figure 1 shows the configuration
for 1794-APB, figure 2 shows the same configuration, but for 3170-PDP.
Note that one byte(00h) has to be placed before the Flag byte when 3170-
PDP is used!
