11-22 Performance and Capacity Specifications
PROFIBUS DP Capacity and Topology Specifications
The following PROFIBUS specifications are independent of the
interface to ProcessLogix:
• PROFIBUS DP supports a maximum of 126 station addresses,
including, masters, slaves and active repeaters.
• The maximum number of entries in the PBIM configuration
table is 100.
Table 11.T Profibus Capacity/Topology Specifications
PFB Module and PROFIBUS Block Specifications
Note: The PROFIBUS interface module hardware component is the SST-PFB-CLX, and is referred to herein as the PFB Module. This device
acts as the “master” on the PROFIBUS-DP network. Each PFB module is represented as a block in the CEE, which is referred to as the
PROFIBUS Interface Module Block (PBIM).
PROFIBUS Communication Profiles Supported DP (only)
PROFIBUS Baud Rates Supported 12 MBps, 6 MBps, 3 MBps, 1.5 MBps, 500 KBps, 187.5 KBps,
93.75 KBps, 19.2 KBps, 9.6 KBps,
Support for Multi-Master Configurations Yes
Support for PROFIBUS Slave Diagnostics No
Valid PROFIBUS Station address range 0 - 125
Maximum number of modules per PBIM block (identified by a unique
station/module number combination) 100
Maximum Input Data Size per PFB Module
(all slave stations)
496 bytes
(valid range = 4-499)
Maximum Output Data Size per PFB Module
(all slave stations)
492 bytes
(valid range = 4-495)
PROFIBUS Device Profiles Supported
(with custom function blocks)
PROFIDRIVE, Encoder
Devices supported with custom function blocks
Siemens Simatic
®
ET200M I/O, Siemens Simocode 3UF5 Motor Protection and
Control Unit
Data types supported by the “Generic” PROFIBUS Channel Blocks
(1) Single bit (Discrete),
8 bit signed/unsigned integer,
16 bit signed/unsigned integer,
32 bit signed integer
(1) The “generic” function blocks are capable of communicating with various PROFIBUS devices. The data types required/supplied by the device are a consideration in the
determination of whether or not a specific device can be used with these blocks.
