Hello hannibar, I'm not sure wether this is the right information or not: [:(] In the documentation Loadable Driver for Point-to-Point CPs MODBUS Protocol RTU-Format S7 is Master I found the information, that the datatransfer between CPU and CP in the S7-400 are the SFBs BSEND and BRCV (capture 6.2) This SFBs you will find in the Standard Libary within STEP7. Best regards Sabine |
