HMS Anybus CompactCom 30 User Manual

11 Network Specific — Modbus-TCP
11.1 Modbus Registers
Rearrangements have been made in the Modbus register map, because process data sizes
have been increased to 1536 bytes in each direction. An existing PLC configuration need to be
changed to use the new addresses. No difference on the application side.

11.2 BOOL arrays
Process data mapped BOOL arrays are not compressed to bit-fields on the network in the 40-
series, but handled as a normal 8-bit datatype. To create bit-arrays in the 40-series, use the
new datatypes BITx instead.
