3.2 Internal Register Structures
The
SIMA
TIC 505–2557 module in the high-density mode logs in to the
controller as 32 WX input registers, 32 WY output registers and 16 X and
16 Y discrete inputs and outputs. This high-density configuration provides
support for reading the raw data and the processed data, and for writing the
configuration data to the module. Refer to
section
3.7 for a one-page
summary of I/O assignments.
Starting login addresses and the locations of their corresponding registers
are shown in T

The
word input content of the module consists of 32 WX input registers.
These registers present the raw measured data and the processed data to
the controller
.
WX33 – WX48 contain the converted data in engineering units for the
sixteen input channels, as shown in T
