A-B 3150-MCM
The Allen-Bradley 3150-MCM is a communication module designed for the Allen-Bradley SLC
500 Programmable Logic Controller (PLC) platform. It functions as a Modbus Master and/or Slave communication interface, allowing the SLC 500 to communicate with devices that support the Modbus RTU or ASCII protocols. This module enables the integration of the SLC 500 system with various Modbus-compatible devices such as other PLCs, Human-Machine Interfaces (HMIs), motor drives, and sensors. The module exchanges data between the SLC processor and the Modbus network through a dedicated register space.
Key Characteristics:
- Modbus Master and Slave Functionality: Can initiate communication with Modbus slave devices and respond to requests from Modbus master devices.
- Supports Modbus RTU and ASCII: Offers flexibility in communicating with different types of Modbus devices.
- Interface with SLC 500: Designed to be installed directly into the backplane of an SLC 500 chassis.
- Data Exchange via Registers: Utilizes a dedicated 4000-word register space for data transfer between the SLC processor and the Modbus network.
- Asynchronous Data Transfer: The data transfer between the SLC processor and the Modbus network operates independently.
Product Parameters:
- Manufacturer: ProSoft Technology (This module was also sold under the Allen-Bradley brand, but ProSoft Technology was a key manufacturer).
- Part Number: 3150-MCM
- Product Type: Modbus Master/Slave Communication Module
- Compatibility: Allen-Bradley SLC 500 PLC systems
