I'm currently working on an application where I need to communicate Quadlog /CCM+ system with an Allen Bradley Controllogix processor. I want read/write data from/to n Allen Bradley configured as a MODBUS Slave device. I know holding, input registers, serial communication settings, but I'd like to know what else is necessary to be
known? Thanks for help.

you must need a prosoft module (MCM module). with that module, your contollogix processor can communicate with your quadlog/ccm+ system via RS-422, RS-232 or RS-485 as master or slave.

i can help you solve that problem. where do u live??

You will need to buy the modbus master program for the quadlog. You will need to set up your communications settings, i.e. Baud rate, parity, stop bits, modbus id and etc.

You will need proper connections between the Quadlog port and the modbus communications module in the A-B controllogix rack (chk your processor and see if it has rs-232 port for connection to quadlog port and remember rs-232 is limited to approx 50 feet of cable).
You will need to program controllogix for the modbus communications.

You will have to decide what type of data format your going to use ie integer, floating point, binary, etc.

You will need to come up with modbus map.

Good Luck

Another option may be to interface serial to serial with the DataLink DL4000-DMX (DF1 to Modbus) http://www.datalinkgateways.com/products_dl4000-dmx.htm

or over DH+ with DL3500-DH+/Modbus. http://www.datalinkgateways.com/products_dl3500dhplusmodbus.htm
