Hello Veeback; I am afraid the message that comes with Error 11 is very definite: the version of your CPU is not supported by the Modbus library for S7-200 CPUs. The attachment is taken from the S7-200 System Manual, a document I suggest you keed close-by if you intend to develop any control system on his family of PLCs: S7-200 System Manual https://support.industry.siemens.com/cs/br/en/view/1109582 Hope this helps, Daniel Chartier |

Hello There is an Old Modbus Sample Program that you will find on the S7-200 Tips and Tricks CD which you can download from here : What are S7-200 programming tips and where can you procure them? I believe , this example should work on V1.x also. as Hardware requirement says : No Restrictions Unfortunately the example is only for use as Modbus Slave. However if you know your Microwin , it is possible ( With some effort ) to use the various components for Application as Modbus Master , including CRC Calculation logic. This CD is a treasure trove of Tips and Tricks for S7-200. I wonder if there is an updated copy available for the later versions. Hope this helps Cheers Navnag |
