Commissioning
7.1
Connected HART field devices
We recommend you commission the connected HART field device before commissioning the
WirelessHART Adapter. In addition to configuring the field device, the following parameters must
also be configured:
•
HART address
= 1
The field device is set to the multidrop mode and the current signal is frozen at 4 mA for the "two-
wire field device with power supplied by the WirelessHART Adapter" configuration.
If more than one field device is connected to the WirelessHART Adapter, each field device must
be assigned its own individual address between 1 and 14, such as 1, 2, 3, 4 for instance. Up to
four connected field devices are allowed to operate in the multidrop mode with an external power
supply.
•
Device Tag
: This is used to identify the measuring point.
•
Long Tag
: This is used to identify the field device in the network.
The
Long Tag
parameter is available with HART Version 6.0 and higher. In older versions, the
Message
parameter is used for this purpose.
Start commissioning as indicated below for the "two-wire field device with power supplied by the
WirelessHART Adapter" configuration. You can perform commissioning via the display, Field Xpert
or FieldCare.
1. Keep pressing the push button on the WirelessHART Adapter until the red light emitting diode
flashes.
2. Power is supplied to the field device for 5 minutes. You can specify the length of time in the
Configuration Time
parameter in the adapter DTM.
See the "Field device power" section on Page
Note!
• You may not change the address if the field device is connected in a circuit with a PLC or a remote
I/O. This address is 0 in most instances.
• It is not necessary to assign different HART addresses to different WirelessHART Adapters. The
address that is used in the wireless network contains the serial number of the WirelessHART
Adapter and is therefore unique.
• 4 to 20 mA field devices do not require preconfiguration. Scaling and linearization are configured
in the adapter DTM.
