MOLEX SST-PB3-CLX PAC/PLC Communication Module

Description

The MOLEX SST-PB3-CLX module is a high-performance communication module designed specifically for industrial automation systems, particularly compatible with the Rockwell ControlLogix platform. The following is a detailed analysis of the module:

1、 Basic Information
Manufacturer: Molex Corporation
Type: Slot type communication module, Profibus scanner module
Weight: 430 grams
Working voltage: 220V (from sales information, may vary depending on specific application scenarios)
Working temperature range: 0 to 60 degrees Celsius
2、 Main functions and features
Communication ability:
Supports Profibus DP master and slave modes, and communicates through the equipped PROFIBUS D-sub female module with 9 pins.
PROFIBUS scanners that can be used for Allen Bradley 1756 backplane systems and Honeywell PlantScape systems, enabling communication links between CLX processors and remote I/O devices located on the PROFIBUS network.

Supports standard transmission speeds for multiple Profibus networks, including 9600, 19200, 31.25k, 45.45k, 93.75k, 187.5k, 500k, 1.5M, 3M, 6M, and 12M baud rates.
The SST PROFIBUS configuration tool can be used for configuration and programming, which helps to configure I/O on the network.
Data processing and mapping:
Supports two data transfer modes: direct mode and paging mode. The direct mode allows mapping PROFIBUS data in the I/O processor image, while the paging mode allows accessing PROFIBUS data from a user-defined data space set to Logix CPU memory.
Input and output data can be mapped to the I/O data array of the ControlLogix 5550 controller.
Status display and fault detection:
Equipped with an LCD panel and 3 LED indicator lights (used to display communication, system, and normal status respectively), it helps users quickly identify the working status of the module and any potential issues.
The COMM LED indicates the network health status, the SYS LED indicates the health status of the PROFIBUS master station, and the OK LED indicates whether the module initialization is complete and whether the module is ready to run.
3、 Application and compatibility
Application scenario: Suitable for industrial automation systems that require efficient and reliable communication, especially those that require data exchange with other PROFIBUS compatible devices.
Compatibility: Compatible with Allen Bradley’s ControlLogix series and Honeywell PlantScape system, can be directly installed into any available slot of the 1756 chassis.
4、 Other characteristics
Module quantity: Up to eight SST-PB3-CLX modules can be installed in a single rack, enabling extensive communication between Logix processors and Profibus DP slave devices.
Device Connection: Supports up to 125 DP slave devices for communication, with each connected slave device supporting up to 122 input data words and 122 output data words.
Configurability: Can be configured to listen for up to 15 connections and 1 output connection, supports Profibus DPV1 master station services, including various read/write, idle, abort, and other operations.
In summary, the MOLEX SST-PB3-CLX module is a powerful and stable communication module designed specifically for industrial automation systems, capable of meeting efficient and reliable communication needs.
