PACTware
TM
PACTware (PACTware – Process Automation Configuration Tool) is
a manufacturer-independent operating software for devices. In the past, it was often necessary
to use multiple manufacturer-specific programs to be able to operate different devices.
PACTware enables you to operate any number of devices with just this software. PACTware is
not only a configuration tool, it also offers an interface to HART-compatible field devices as
well as to bus systems such as PROFIBUS, MODBUS, and ControlNet. PACTware offers
many features that allow users to simplify the plant documentation, to create trend curves, and
to monitor signals using HART data.
Point-to-point connection
In point-to-point connections, only two communication participants can be connected to one
segment (core pair). A point-to-point connection is, for example, the master-slave connection
of multiplexer device to field device.
Primary variable
This variable is a process measured value of the field device. The unit differs according to the
HART command (see commands 1, 2 and 3). The primary variable of a pressure transducer
may be, for example, the measured process pressure in bar.
Primary master
See Multi master
Secondary variable
This variable is a further, additional process measured value of the field device. Up to 4
additional values are supported via HART. This variable can only be read using
HART command 3.
Secondary master
See Multi master
Slave
A device in a master-slave system that receives commands from a master. A slave cannot
initiate a transmission request.
Smart field device
Intelligent, programmable field device with microprocessor and memory which is able to
perform calculations, integrated diagnostics, and fault reports and can communicate with a
remote control.
Tag
Unique identifier of the C&I point (Control and Instrumentation technology) of the field device
within a process plant.
