Description Niobrara's TSX Compact Universal Communications Module (CUCM-O & CUCM-OE) are programmable serial communication modules for Schneider Automation's TSX Compact PLC with two serial ports, a PLC interface, Indicator LEDs, a real-time clock, a TCP/IP stack, two application areas, and internal registers. The CUCM-OE offers an additional Ethernet port.
Uses for the CUCM Data Concentrator
Applications The engineers at Niobrara have written several applications
The source code for these applications is available at www.niobrara.com. The applications can be used as is or modified to solve your PLC communication problem or used as
examples to start your own CUCM application development.
QUCM Language The CUCM 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.
Applications developed for the QUCM can be run in the CUCM. See the application notes for the QUCM here.
Although the CUCM is designed for user programming, many companies choose to have Niobrara write their CUCM code. Contact Niobrara for a quote.
Application Areas The CUCM can run two simultaneous applications. Both applications have access to the PLC backplane, the serial ports, the LED array, the real-time clock, the TCP/IP stack, and the internal registers. The applications can be independent or they can cooperate, using mailbox registers to exchange data.
Serial Ports The two serial ports on the CUCM are switch selectable RS-232 or RS-485. 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 (CUCM-OE only) The single 10BaseT RJ45 Ethernet port defaults to Modbus/TCP protocol. The CUCM 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 CUCM can be either an I/O Module or an Option Adapter.
When the CUCM is configured as an option-module:
As an I/O module, the CUCM can be used:
LEDs / Real-Time Clock The CUCM has eight LEDs under Application control. It also has LEDs to indicate Application 1 RUN, Application 2 RUN, Port 1 transmit and receive, Port 2 transmit and receive, Ethernet transmit and receive, as well as Module Active, Ready, Run, Link, Collision, and Fault.
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:
