I want to communicate Modbus Slave with S7-200 CPU, but in Instruction Library I was not found the Modbus block, but in “Standard Libs” folder I found the “modbuse” file in that I used the block for communicating with Modbus Slave,

My problem is I can’t copy the block, for that how can I move this Instruction in Library .

Hello

Look at Where in STEP 7 Micro/WIN can I find the operations libraries for the Modbus RTU protocol? Also I think this FAQ would be helpfull: How do you implement MODBUS communication with S7-200?

Hope this will helps a little...

regards
