SST-PFB-SLC PROFIBUS Communications Module

The following special terms are used throughout this guide: 

Card The SLC 500 network interface card 

Channel A PROFIBUS network interface on the card 

Firmware The embedded software module that gets loaded to the scanner’s memory and runs on the scanner, enabling it to respond to commands from the host and manage network communications. 

Module A synonym for Scanner 

Scanner The SST-PB3-SLC scanner module, consisting of hardware and firmware

Scanner Capabilities The SST-PB3-SLC is the PROFIBUS scanner for the SLC 500. It enables communication between an SLC processor (SLC 5/03 or later) and DP remote I/O devices on a PROFIBUS network, acting as a PROFIBUS DP remote I/O scanner. It:

• Can scan up to 125 Slaves 

• 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 1032 words of input data and 1032 words of output data 

• If you use Siemens’s COM PROFIBUS to configure the scanner, it supports up to 160 words of input data and 160 words of output data 

• 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. 

• Supports all standard PROFIBUS baud rates (9600, 19200, 31.25k, 45.45k, 93.75k, 187.5k, 500k, 1.5M, 3M, 6M, 12M) 

• Can act as a DP Slave to another DP Master on the same network

 • Supports up to 122 words of input data and 122 words of output data as a Slave 

• Supports up to four FDL SAPs and up to four FDL message blocks 

• Supports DPV1 Master Class 1 and Class 2 messaging
