Description

Datalogic CM1746 RFID Module. ALLEN BRADLEY PLC INTERFACE RF ID SYSTEM | 25 MHz i386 Processor | 512KB Flash Memory | 512KB RAM | DOS Compatible Operating System | LED Status Indicators Simple Type: RFID Module Escort Memory Systems’ CM1746 RFID module is a plug-in module for the Allen-Bradley SLC 500 programmable controller family with 1746 backplane. With the CM1746, the Allen-Bradley PLC has access to information in the Escort Memory Systems’ HS/HL and HMS-Series read/write tags and ES-Series read only tags. The powerful programmable processor in the CM1746 regulates serial and RFID transfers thus freeing the PLC from communication tasks with Escort Memory Systems devices. The CM1746 plugs directly into the PLC backplane using the PLC’s 1746 technology bus. It has the same mechanical housing, backplane connections, and interface protocols found in other Allen-Bradley modules for the SLC 500 family. The CM1746 benefits from the proven reliability and durability of this PLC family. Two ports are dedicated to HS500-Series and HL500-Series read/write antennas, while HMS-Series Reader/Writers and RS Read Only antennas must be connected to a serial port. The HMS800 and HMS805 are RS232 communications only and two may be connected to the CM1746 through COM1 and COM2. COM1 is used to load the new software into the CM1746 or for point-topoint RS232 connection. The COM2 serial port also supports MUX32/RS485 protocol. There are special commands in the standard program for addressing slave devices on the multidrop line. For other serial devices the COM2 port may be configured as an RS232, RS422 or RS485 serial port. A DOS compatible processor makes it easy for a user to program the CM1746. An industry standard compiler gives the user a familiar, inexpensive and well supported development environment. A general purpose optically isolated digital input is provided for connection of a presence sensor, proximity sensor, or relay. An optically isolated output can be used to send trigger signals to readers, or to operate a relay coil. Download the datasheet (PDF)
