Engineering
The
Engineering
section consists of the following sections:
■
Instrument List
You can freely define an instrument list of all network components before the devices
actually join the network. Hereby you can make sure that a device is associated with the
predefined I/O card number when the network is reformed or the WirelessHART gateway
is reset.
■
MODBUS Mapping
You can create the mapping table for the MODBUS input registers manually, semi-
automatically, or automatically.
Note that the instrument list must be available before you create the mapping table,
because the values for the mapping table are device-related.
Loop Current
Fixed
The loop current is being held at a fixed value and is not responding to
process variations.
More status
available
More status information is available via Command 48 (Read Additional Status
Information).
Cold Start
A power failure or device reset has occurred.
Configuration
Changed
An operation was performed that changed the device's configuration.
Device
Malfunction
The device detected a serious error or failure that compromises device
operation.
Cumulative Extended Device Status
These bits are set to 1 whenever the related status applies to one or more devices (or sub-
devices) connected to the WirelessHART gateway.
Maintenance
Required
One or more wireless devices require maintenance.
Device
Variable Alert
One or more wireless devices have a device variable alert. This bit is set if any
device variable is in alarm or warning state.
Critical Power
Failure
One or more wireless devices have a power failure (e.g. battery low).
Device Operation in Progress
These bits are set to 1 whenever the related procedure is ongoing in one or more devices (or
sub-devices) connected to the WirelessHART gateway. When an operation is ongoing, the
WirelessHART gateway will return a "Busy" response code to any HART message of the host
directed to the relevant device (or sub-device). These bits are not latched and simply reflect
the current operation status.
"Configuration
Changed bit
reset"
procedure
The "Configuration Changed bit" procedure is being performed at one or more
devices.
"Sub-Device
update"
procedure
One or more sub-devices of WirelessHART adapters are being updated.
"Device
update"
procedure
One or more wireless devices are being updated.
