Hello m.schoaib khatana; Librairies of fiunctions for Modbus RTU are available for the S7-200. But (there is always a "but"): Where in STEP 7 Micro/WIN can I find the operations libraries for the Modbus RTU protocol and USS protocol? These libraries (Note: operations libraries for the Modbus RTU protocol and USS protocol ) are not components of the configuration software STEP 7 Micro/WIN, but are ADD ON function libraries. In order to be able to work with the Modbus RTU protocol you must have purchased the software "SIMATIC STEP 7 Micro/WIN ADD ON: Function Library V1.1 (USS + MODBUS) for STEP 7 Micro/WIN 32". The order number for this optional ADD ON function library is: 6ES7830-2BC00-0YX0. Hope this helps, Daniel Chartier |
