Fieldbus Controller 750-841
Adding an offset of 0x0200 to the MODBUS output address lets you read
back output data.
Fig. 3.1-9: Data exchange between MODBUS/TCP master and I/O modules
Starting from address 0x1000 there are the register functions. The register
functions made available in the coupler, can be addressed by the MODBUS
master along with the implemented MODBUS function codes (read/write). To
this effect, the individual register address is entered in place of the address of
a module channel.
Note
For MODBUS mapping, all output data over 256 words resides in the
memory area 0x6000 to 0x62FC, and can be read back with an offset of
1000
More information
You can find a detailed description of the MODBUS addressing in the
chapter „MODBUS Register Mapping“.
