Modbus RTU/ASCII Master/Slave Communication Module
PTQ-MCM
The PTQ Modbus Master/Slave Communication Module allows Schneider Electric Quantum processors to interface easily with other Modbus protocol-compatible devices.The PTQ Modbus module provides an easy way for users of the Schneider Electric Quantum processor to add two Modbus serial ports to the control platform.
The module acts as an Options module for the Quantum platform allowing communication on a Modbus serial network. Compatible devices include not only Modicon® PLCs (almost all support the Modbus protocol) but also a wide range of process and control devices from a variety of manufacturers. Many SCADA packages also support the Modbus protocol.

Slave Specifications
A port configured as a virtual Modbus slave device on the PTQ-MCM module accepts Modbus function code commands of 1, 2, 3, 4, 5, 6, 8, 15, 16, 17, 22 and 23 from an attached Modbus Master unit. A port configured as a Modbus slave permits a remote master to interact with all data contained in the module. This data can be derived from other Modbus slave devices on the network, through a master port, or from the Quantum processor.
Master Specifications
A port configured as a virtual Modbus Master device on the PTQ-MCM module actively issues Modbus commands to other nodes on the Modbus network. One hundred (100) commands are supported on each port. Additionally, the master ports have an optimized polling characteristic that polls slaves with communication problems less frequently. The Quantum processor can be programmed to control the activity on the port by actively selecting commands from the command list to execute or issuing commands directly from the ladder logic.
General Specifications
- Single Slot - Quantum backplane compatible
- The module is recognized as an Options module and has access to PLC memory for data transfer
- Configuration data is stored in non-volatile memory in the ProTalk module
- Configuration software for Microsoft Windows XP, 2000 and NT is included with the module.
- Up to six modules can be placed in a rack
- Local rack - The module must be placed in the same rack as processor.
- Compatible with common Quantum / Unity programming tools.
- Quantum data types supported: 3x, 4x
- High-speed data transfer across backplane provides quick data update times.
