4.2 The development environment
The TD320 is a HMI graphical terminal with an integrated PLC.
It allows a centralization of all the operational logic of the system
that must be supervised and controlled.
The graphical part of the development environment must manage
the visible pages and their fundamental items (e.g. synthesis,
push-buttons, numerical and text edit boxes, images) and the
interaction between various objects and the memory areas (the
memory areas which they must reference for push-buttons,
indicators and images).
The logic of the operation of the system, i.e. the way in which the
memory areas must interact among each other, is instead
managed by the PLC.
The TD320 terminal is also a PLC
, therefore it manages graphics
on one hand, and logic on the other, leaving other connected
PLCs the sole task of "detecting the information" (e.g. digital and
analog inputs, encoders etc.) and "to control the actuators" (e.g.
digital and analog outputs etc.).
The development environment has two sub-environments:
•
TdDesigner:
manages all resources that are strictly related to
the graphics.
•
PLProg:
manages the interactions between the memory areas
of the terminal (Ladder code, common to other PLCs,
essentially the PL250 and TCT500).
