Dear Praveen Patil, You have the right module, connect it as a RS485 module to the master, please look very well if the wiring is ok.. More data is on page 3-61 and 3-14 for the wiring of the module. In the handbook Serial Interface Module ET 200S 1SIyou will find how to program the MODBUS Slave in chapter 3.6 as of page 3-55, The Function Codes 01, 02, 03, 04, 05, 06, 07, 08, 11, 12, 15 and 16 may used. There is like FB80 for the CP341 also a FB81 "S_MODB" that have to be used for the best programming, seeFunction Blocks, Examples and User Manuals for the ET200S 1SI Serial Interface for the blocks and a example. |
I hope that the answer will help, if you have still questions, don't hesitate to ask me. |
