Hello, I have a problem with understanding the Modbus Register list for Comap intelilite amf 25. For example, if I want to read RPM the adress according to the register lsit is 1001. However, since this value in the table is under Modbus functions 03 and 04 which according to TIA portal help use 40001 to 49999 or 30001 to 39999 I am not sure how to use the register list in order to set the MB_Master block. Can anybody help me? ------------------------------------------------------------------------------------------ |

Hello,
pls think simply as Siemens 'system' working for input registers as range 30001 to 39999 and if you need read Holding registers use range 40001-49999, so f.ex. in case of Holding register add to your documentation register +40001. So, if your register is 1001, your destination register is 1001+40001 -> 41002. I think you will be lucky, simply check documentation to Master or Client block in TIA to see that table and how set correct values due also standard FC codes. |
With best regards... |
