<DeviceInformation>
<ModbusMap>
<FailedValue>
This indicates Modbus field
device parameter failure
value. That is, when
parameter value retrieved
from Modbus field device is
equal to this value, it
indicates the device
parameter value is in failure.
For example, if
0xFFFFFFFF represents
Product level measurement
failure for a Modbus field
device, then when CIU
receives that value it
interprets that the Product
level measurement has
failed and sets the Product
Level status accordingly.
When status register is
present in the device (Status
tag information present),
status and validity of the
device parameter would be
determined by CIU based on
Status tag in the status
section and this tag shall be
empty.
Any HEX string as
per the Modbus
field device
manufacturer.
<DeviceInformation>
<ModbusMap>
<Status>
<Name>
This is the device status
parameter name as defined
in the Manufacturer's
product data sheet.
Any string
<DeviceInformation>
<ModbusMap>
<Status>
<ModbusRegisterAddress>
This indicates the Modbus
register address of the
status parameter associated
with device parameter that
needs to be scanned by CIU
888.
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.
300001 to 365535
400001 to 465535
