10.2.2 Bit Services
With the digital bit services, determine or change the statuses of digital input and
output terminals for the following address ranges:

MODBUS Address Addresses in CoDeSys Description
0x0000 – 0x01FF
(0 – 511)
%IX 0.0 ... %IX 32.15
+ offset value
Input process image
Bit-based addressing in MODBUS begins with
the first digital I/O module at the internal data
bus. If analog I/O modules are used, the
address range allocated by these modules is
skipped over by the addressing function (offset
value).
0x0400 – 0x0401
(1024 – 1025)
%IX2300.0 … %IX2300.1 Integrated digital inputs
0x3000 – 0x7FFF
