Hello girish; For the V20 communications with a S7-200 Smart, at least, there is information (and a sample program) available: S7-200 SMART with V20 (MODBUS) https://support.industry.siemens.com/tf/ww/fr/posts/118107/ "Requirement: To operate the MODBUS protocol you must first procure and install the Step 7 Micro/WinSmart" I know nothing of the LG drive, so I suggest you go to the LG site and find out if the drive has a MODBUS RTU channel, what the Modbus mapping looks like, and how you should reuqest the various data you need to exchange. Then you can build the Modbsu data transfer between the CPU and the drive, since you have already the Modbus libraries installed ithrough WinSmart.. Hope this helps, Daniel Chartier |
