Manual
1.5.0
12.3.5.44 Output Fieldbus Variable UDINT Offset (AD
hex
)
The class enables the exchange of data from a particular PLC output variable
from the data area for port 1.
With an offset of 2 bytes to the addresses of the "Output Fieldbus Variable
UDINT (AC
hex
)" class, that means for WAGO-I/O-PRO or CODESYS the PLC
addresses for %QD638 ... %QD765.
Information about Using the Offset
"Offset of 2 bytes" means:
If instance 1 of this class is read, you obtain High-Word of the address %QD638
and the Low-Word of the address %QD639, etc.
If instance 128 is read, you obtain only the High-Word of the address %QD765.

12.3.5.45 Input Fieldbus Variable USINT (B0
hex
)
The class enables the reading of data from a particular PLC input variable from
the data area for port 2.
The instance scope of the "Input Fieldbus Variable USINT" class covers the PLC
input variable data from 1 to 255 from the data area for port 2.
For WAGO-I/O-PRO or CODESYS, that means the PLC addresses for output
variables %IB3064...%IB3318.
