Has anyone developed Modbus Logic without using library bolcks? If yes then please share that program. Because I am also facing the same problem asaru_07. So please give some help on that.

Hi there. Is this a new application or updating an old project? I would strongly recommend against using an S7-200, seeing that it is declared obsolute.. unless you have a mchine from China who still use them in a new packaging. A Modbus block will use up much memory. So if it is an update, please check how much memory you have left on the PLC to play with. I do not have a block you can use.. but you could search what guys are doing for Arduino and see if there is open code to use. Alternatively generate a new thread in the Networks/Communication section.. there is a good possiblity that someone there will be able to assist. Do not forget you could always generate a Support Request. Good luck. w |
