The Datalogic / EMS CM900 AutoID Interface Module is an advanced peripheral for the Modicon 984 Compact PLC rack. The CM900 expands a host PLC’s data collection and dissemination capabilities by providing an RFID antenna port and serial communication facilities.

The CM900’s fully-buffered, bi-directional serial communications port is configurable to support RS232 and RS422 communications formats. It can be set to communicate with a wide variety of devices, via selectable baud rate, parity, and number of data bits and stop bits. A dedicated RS232 port is also provided for programming and debugging.

The RFID antenna port is compatible with Escort Memory Systems industry leading EMS® Read/Write RFID components. The communications connection between the CM900 and antenna is via two twisted pair wires (four wires) with a maximum cable length of 1,200 meters (4,000 ft).

The CM900 also features 32K bytes of nonvolatile EEPROM program storage as well as 32K bytes of system RAM. Seven status LEDs mounted on the front of the CM900 greatly assist program debugging and maintenance.
