2.1 System
Overview
The SST-PFB-SLC is the ProfiBus scanner for the SLC 500. It enables
communication between a SLC processor (SLC 5/03 or later) and DP remote
I/O devices on a ProfiBus network. It acts as a ProfiBus DP remote I/O
scanner to scan up to 96 slaves. The scanner supports up to 244 bytes of input
data and 244 bytes of output data per slave.
If you use the SST ProfiBus Configuration Tool to configure the scanner, you
can have up to 1000 words of input data and 1000 words of output data.
If you use Siemens COM PROFIBUS to configure the scanner, it supports up
to 160 words of input data and 160 words of output data in total.
The scanner can reside in any slot in the local SLC chassis except slot 0
(reserved for the SLC processor). You can have multiple scanners in the same
rack.
The scanner supports all standard ProfiBus baud rates (9600, 19200, 93.75k,
187.5k, 500k, 750k, 1.5M, 3M, 6M, 12M)
You configure the I/O on the DP network using either the SST ProfiBus
Configuration Tool or Siemens COM PROFIBUS configuration software.
The SST configuration tool exports the configuration to a *.bss file (binary),
while COM PROFIBUS exports the configuration to a *.2bf file (binary).
You upload the configuration to the scanner via the serial port on the scanner,
using an Xmodem transfer from any serial communications software.
The scanner stores this configuration in flash memory on the scanner so you
don’t need to upload the configuration every time you start the SLC.
The input and output data for the slaves is mapped into SLC I, O, M0 and M1
files. The mapping depends on the addresses you assign in the configuration
you create with either configuration tool.
The scanner does not require setting up a G file in the SLC. All the
configuration is done with the SST configuration tool or COM PROFIBUS.
The scanner maintains the following status information about the network
and the I/O modules on the network:
• slave

• network
