Answer question
AC800M Controller as Modbus Slave
We are facing following issues AC800M able to talk to Invensys fOXBRO DCS.
Invensys side act as master and AC800M as slave
Invensy need to accesses all type of registers in the below range
1-9999 0000 to 270E Discrete Output Coils 10001-19999 0000 to 270E Discrete Input Contacts 30001-39999 0000 to 270E Analog Input Registers 40001-49999 0000 to 270E Analog Output Holding Registers
In ABB side we have only %MW and %MX for accessing the variable, Invensys can read with Function code 4 first address only if the address in AC800M Controller is configured as %MW1
Is this configuration is correct or not ?
Addressing format is correct ?
