CIU 888
Description
Some Modbus field device
adds an offset to the data it
exposes to the Modbus host.
Hence this parameter
indicates the offset factor
used in the exposed data
from the field device so that
CIU can subtract the offset
from the retrieved value.
If Scaling and offset are not
applicable then this tag can
be left empty
This indicates the default
scanning priority for a device
parameter. This can be
configured as Foreground /
Background. While scanning
the field device, if multiple
field device parameters are
retrieved in one Modbus
request, then highest priority
within the scanned field
device parameters is set for
that request.
For example, if Product
Level (Foreground priority),
Product Temperature
(Background priority),
Product Density
(Background priority) are
retrieved from the field
device with a single Modbus
request, then the Modbus
request would be scheduled
to the field with Foreground
priority.
This can be overridden
through Modbus Data Input
configuration in CIU 888
service tool.
This indicates the device
unit type of the parameter
configured in the Modbus
field device.
If value for this tag is set as
"ANY" then CIU 888 service
tool shall display all the
device supported units in its
User Interface for this
parameter in Modbus Data
Input configuration.
