TZIDC DIGITAL POSITIONER | DS/TZIDC-EN REV. G

Communication
FDI – Field Device Integration
The Device Type Driver for the positioner is based on the FDI
technology and can either be integrated into a control system
or loaded on a PC with ABB Ability™ Field Information
Manager (FIM).
This allows you to work with the same user interface in the
commissioning phase, during operation, and for service tasks
involving monitoring the device, setting parameters, and
reading out data.
DTM
The DTM (Device Type Manager) for the positioner TZIDC is
based on FDT / DTM technology (FDT 1.2 / 1.2.1) and can
either be integrated into a control system or loaded on a PC
with FDT framework. This allows you to work with the same
user interface in the commissioning phase, during operation,
and for service tasks involving monitoring the device, setting
parameters, and reading out data.
Communication is based on the HART® protocol.
Communication with the device can take place optionally via
an LCI adapter with USB interface on the positioner or an FSK
modem at any point on the 20 mA signal line. Reading out
data from the device has no effect on the operation in
progress. Newly set parameters are saved in the non-volatile
memory directly upon download to the device, and become
active immediately.
LCI Adapter
You can easily connect your positioner to a PC, e.g. in the
workshop or in the commissioning phase, by using the LCI
adapter.
The signals at the USB output of the PC are translated via an
LCI adapter to the level of the local communication interface
(LCI) of the positioner.

FSK modem
Digital frequency modulated long distance communication
(Frequency Shift Keying) with the positioner is established
via the FSK modem.
Tapping is possible at any chosen point of the 20 mA signal
line.
We recommend a modem with electrical isolation. This
modem is bus-compatible when used with isolating
amplifiers. The connection of Ex-field devices is also possible
provided the modem is operated outside the Ex area or it
corresponds to the Ex approval requirements and the Ex
connection data of our device.

SQUAWK
SQUAWK is a standardized command of the HART®7
communication standard. If a SQUAWK command is sent to
the device after connection (HART® command '0'), the
flashing of the lower menu line in the display makes it easier
to visually identify the affected device in an installation.
