10.6 Commissioning Aids
Two handheld devices are available to aid
commissioning and fault finding. The first is the
Paktester, (Field Test Unit), which may be used to
interrogate and control a single field unit via the 2-wire
interface. This requires the disconnection of the field
unit from a live loop. The Field Test Unit can also
program various field unit parameters.
The second device is the Master Station Test Unit (or
Pakreader) which communicates with a master station
via the host serial links. Modbus discrete bits and
registers may be read from and written to, allowing a
master station and field units to be monitored and
controlled.
