Hello Sunil, How do you establish MODBUS-RTU communication with STEP 7 (TIA Portal) V11 for the SIMATIC S7-1200? Hope this helps |

Hello Sunil, Before connecting the slaves to S7-1200, you check the slaves with MODSCAN software . Then you can easily hook up the slaves to the S7-1200 master. Lot of time can be saved in this. |
