Hello, the data exchange between PLC and drive can be done in different ways and there are a lot of standard solutions and examples available here in SIOS. The cyclic communication is done via telegrams. You can use standard telegrams (like telegram 1) or free telegrams and assign your own data. When using standard telegrams there are ready to use function blocks for the PLC to do the communication. For example SINA_SPEED in case of using telegram 1. Here the library with the blocks: https://support.industry.siemens.com/cs/ww/en/view/109475044 Here just one example of PLC <-> drive data exchange: https://support.industry.siemens.com/cs/ww/de/view/70155469 (it is with S7-1200 and G120 but it is quite the same for S120 and G120) |
With best regards, |
