Configuration Manual
CIU 888
Description
This indicates the number of
Modbus registers defined for
the Modbus field device
status parameter that needs
to be scanned by CIU 888.
This indicates the Modbus
datatype for the Modbus
field device status parameter
that needs to be scanned by
CIU 888.
This indicates the Modbus
field device's byte order for
16 bit status data. Based on
this configuration, CIU 888
inteprets the field device
status value with correct
byte ordering.
There can be 2 formats in
which data can be exposed
(i) LSB first (ii) MSB first.
Based on this configuration
CIU interprets the data and
converts it to its internal data
format.
This indicates the Modbus
field device's word order for
32 bit status data. Based on
this configuration, CIU 888
interprets the field device
status value with correct
word ordering.
There can be 2 formats in
which data can be exposed
(i) LSW first (ii) MSW first.
Based on this configuration
CIU interprets the data and
converts it to its internal data
format.
