Description
This indicates the GPU address of the Honeywell TRL2
field device.
This indicates the CIU parameter name to which the
scanned Modbus field device parameter has to be
mapped. CIU Service tool displays all the CIU Parame-
ters which can be scanned from Modbus field devices in
a drop down menu.
This is the Modbus field device type. For example, this
can be Smartline Level Transmitter, E+H ProServo. CIU
Service tool displays all the supported device types in a
drop down menu.
Each Modbus device is addressed with a unique slave
ID. That is, when a request is received by a Modbus
device, it checks the Modbus slave ID in the request
and if it matches with its configured slave ID, it
responds back, else it skips the request. This indicates
the Modbus RTU address of the field device.
This parameter indicates the address from where the
Modbus mapping starts for a device. In case of Modbus
field devices that are directly connected to CIU this
could be 0 and in case of Modbus data concentrator,
the user has to configure it based on the device number
in the Modbus data concentrator. For example, for E+H
ProServo Modbus field device, this value could be 0
and for Smartline Level Transmitter connected as sec-
ond HART device to a HCS Modbus-HART converter,
this value could be 264.
This indicates the name of the parameter in the Modbus
field device which needs to be scanned by CIU. This
parameter would be used by CIU to interpret data in
case of custom value mapping.
This indicates the relative Modbus address of the
selected parameter.
Absolute Modbus address of Parameter = Device Mod-
bus Start Address + Modbus Register Address
This indicates the scanning priority for a device parame-
ter. This can be configured as Foreground / Back-
ground. 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.
