DL2000-CMX
Modbus to DH+

The DataLink DL2000-CMX provides high speed interconnectivity between an Allen-Bradley DH+ and a Modbus network. The -CMX can be any station on DH+ and can be set to be either Modbus Master or Modbus Slave. Master mode enables any DH+ station to read or write up to 100 words (per message) to any 4xxxx register at any Modbus Slave address from 1 to 255. Slave mode enables a Modbus Master to read or write up to 1600 coils or 100 registers (per message) to bit or integer files in any PLC-5 station on DH+ (except 0). Modbus commands to address 0 can be "broadcast" to a selected range of DH+ stations.
