15 Modbus TCP/IP signal list
See section 9.10 and 13.1 for Ethernet connection setup and parameters.
NOTICE
The tables in this section show the Modbus addresses as 16-bit words (%MW). When reading a double
word (%MD), the address must be divided by two. Example (see first line in section 15.3): “number of
enabled compressors” can be read in address %MD20016, which corresponds to %MW40032
- %MW40033.
