The QUCM comes from the factory with the Routing and Protocol Conversion (RPC) application which supports all of the important Schneider North American serial protocols: Modbus RTU or ASCII, master or slave; SY/MAX Point-to-Point or Net-to-Net; Plogic, PNIM and RNIM (master or slave); Dual Modbus & RNIM master (drop Modbus devices on RNIM radio networks); Dual Modbus & SY/MAX slave.

• Read data from external devices and/or the PLC.
• Allow external devices and/or the PLC to write data to the QUCM.
• Both the PLC and external devices can read the gathered data.
• Time-stamp data for later retrieval.

• Allow devices with different protocols on separate ports to communicate.
• The PLC can use standard MSTRs to read/write non-Modbus devices.
• Non-Modbus devices and read/write the QUCM or the PLC.

• Read/write Modbus Slaves devices from the PLC or the User Application.
• Use MSTRs to read 0x, 1x, 3x, 4x values.
• Use MSTRs to write 0x coils and 4x holding registers.

• Read, write and program the PLC.
• Read and write the QUCM.

• Send and receive e-mails for alarm conditions.

• Access device data and configure setup parameters with a web page.

• Allow Ethernet clients to access PLC and serial slaves.
• Allow serial master to access PLC and Ethernet servers.

• Interfacing an ACCU-SORT Scanner to a Quantum PLC.
• Interfacing Modbus RTU master to 3694(R) devices.
• Interfacing Modbus RTU master to an Allen Bradley® DF1 device.
• Interfacing Modbus RTU master to ENRON/Daniel Modbus Slaves.
• Gathering data from Simpson Hawk® meters for the Quantum PLC.

The source code for these applications is available here. The applications can be used as is or modified to solve your PLC communication problem or used as examples to start your own QUCM application development.

Although the QUCM is designed for user programming, many companies choose to have Niobrara write their QUCM code. Contact Niobrara for a quote.

• Be a Master or a Slave device while multidropping up to 32 devices off of either port
• Build a Protocol Converter
• Build a Data Concentrator for serial or Ethernet devices
• Use the PLC to trigger messages to printers or signs
• Bring data into the PLC from barcode readers, scales, and other ASCII devices
• Build a gateway to allow ASCII devices onto the Ethernet network
• Dial-out to your ISP and communicate on the Internet using PPP

When the QUCM is configured as an option-module:

• The backplane acts as a bidirectional Modbus port giving both the Quantum processor and the QUCM access to the other's register space.
• The PLC can be programmed from the QUCM.
• Using standard MSTRs, the PLC can speak new Serial Protocols.
• Requires a free slot in the main rack

As an I/O module, the QUCM can be used:

• In any slot in any Quantum rack; local, distributed or remote.
• In applications that require fewer than 32 registers in and 32 registers out.

A real-time clock is available to the applications and is especially useful for scheduling events or time-stamping data.

The CUCM is available as:
     * QUCM-O     with two switch-selectable RS-232/RS-485 ports.
     * QUCM-OE     with two switch-selectable RS-232/RS-485 ports, one 10BaseT Ethernet port

The CUCM has the following equipment available:
     * MM1     PC to CUCM configuration cable
     * BB85     DIN-rail mount breakout box, RJ45 to screw-terminal connector w/ MM0 cable
     * QXBP-001     Single-slot rack with built-in power supply for stand-alone applications
     * DDC2I     Optically-isolated RS-232 to RS-485 converter, DIN-rail mount w/ MM0 cable
