CIU 888
Description
This indicates the relative
Modbus address of a
parameter in the Modbus
field device.
Absolute Modbus address of
Parameter
= Device Modbus
Start Address + Modbus
Register Address
This is the 6 digit Modbus
Register address of the
device parameter. The first
digit indicates the Modbus
function code (3 for Input
registers and 4 for Holding
registers). Second to Sixth
digits indicates the Modbus
register address defined by
the device manufacturer. 0
to 65535 registers can be
addressed. For example to
address holding register 0 in
device, 400001 would be set
here.
This indicates the number of
Modbus registers defined for
the selected parameter.
The data can be exposed in
different data types by
different Modbus field
devices. This parameter
indicates the Modbus data
type in which data is
exposed by the field device
so that CIU can interpret the
data accordingly and convert
it to its internal data format.
Refer to section H.18 for the
list of supported Modbus
data types.
