Hello Nguyen; Here is a basic document from ABB showing how to use Modbus RTU with a ACS500: Modbus RTU - Control Systems Application and Knowledge Store On the S7-1200 side, if you need help for the CM 1241 (serial communication module) see the following FAQ: How do you establish a MODBUS-RTU communication with STEP 7 (TIA Portal) for the SIMATIC S7-1200? There are links inside to more information and an Application example that could help you develop your project. Hope this helps, |

Hey, First you need to tell us with which PLC you are trying to read/writte data to ACS550. I suppose you are speaking about MODBUS RTU and PLC is master Here is an example project from S7-1200 PLC. https://support.industry.siemens.com/cs/document/47756141/how-do-you-establish-a-modbus-rtu-communication-with-step-7-(tia-portal)-for-the-simatic-s7-1200-?dti=0&lc=en-WW You need to find ACS550 MODBUS table with register address, I usually try to read just one data, if I manage to do that I expand my program to LOOP all data I need. Besides this example you need to connect everything good (serial cable or just put 2 wires between PLC CM module and ACS550. If you manage to start PLC example you can read error codes to find out what you didnt do well. Step by step you will get it working |
