User Programmable Application
Description Niobrara's Quantum Universal Communications Modules (QUCM+002, QUCM+102 & QUCM+204) are programmable serial communication modules for Schneider Automation's Quantum® PLC with two or more serial ports, a PLC interface, a LCD display with keypad, a real-time clock, a TCP/IP stack, and internal registers. The QUCM+102 and QUCM+204 offers Ethernet port(s).
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.

Applications The engineers at Niobrara have written several applications
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.
QUCM Language The QUCM is programmed via Niobrara's QUCM language. The language has a BASIC-like structure which makes it easy to read and follow. Powerful language extensions for data communications and PLC interfacing make it ideal for use as a PLC communication language. A TCP/IP stack is built in, making it easy to write application layer protocols using TCP, UDP, PPP, and IP. The language is compiled for the fastest possible execution. The compiler is included at no extra charge.
Although the QUCM is designed for user programming, many companies choose to have Niobrara write their QUCM code. Contact Niobrara for a quote.
Application Areas The QUCM can run a single applications with up to 64 parallel threads. All threads have access to the PLC backplane, the serial ports, the LCD display, the real-time clock, the TCP/IP stack, and the internal registers.
Serial Ports The serial ports 1 and 2 on all QUCMs are software selectable RS-232 or RS-485. The QUCM+204 ports 3 and 4 are fixed RS-232. They use Modicon's pinouts, so standard cables work well. They are independently configurable as to baud rate, parity, data bits, and stop bits. Write the protocol of your equipment to:
Several serial protocols have been implemented in various products and are available online:
Ethernet Port (QUCM+102 and QUCM+204 only) The 100BaseT RJ45 Ethernet port defaults to Modbus/TCP protocol. The QUCM has a TCP/IP stack which the user's application can access for easy implementation of various application layer protocols. Several application layer protocols have been implemented; examples are available online.
Backplane The programmer has a choice of backplane interfaces. The QUCM can be either an I/O Module or an Option Adapter.
When the QUCM is configured as an option-module:
As an I/O module, the QUCM can be used:
LCD / Real-Time Clock The QUCM has a high resolution LCD display under Application control. It also has a 5 button keypad that may be read by the application.
A real-time clock is available to the applications and is especially useful for scheduling events or time-stamping data.
Miscellaneous In applications not requiring a PLC, the QUCM can be used stand-alone with Niobrara's QXBP-001. To connect PC COM: port to the QUCM use an MM1 cable. To break-out the RJ-45 connector to screw terminals use a BB85. For optically isolated RS-485 use the DDC2I.
