13.6 Commissioning Aids
Two handheld devices are available to aid commissioning and fault finding. The first is the Paktester,
(Field Test Unit), that 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.
