Setting and resetting bits in the PLC
Bits in the PLC can be manipulated by means of appropriately configured buttons and
function keys. This enables active intervention in process events.
Input/Output of PLC process values
Input/Output fields are provided with which process values can be displayed and
modified directly. Entries can be assigned limit values and protected by passwords.
Various representation formats are available for the output, e.g. decimal, binary or
symbolic text are possible.
Displaying PLC process values graphically
Bars represent a PLC value in the form of a rectangular area. They are suited, for
example, for representing fill levels.
Integrating graphics
Graphic fields can be used to provide users with a visual representation of a system or
process.
Integrating v ector graphic obj ects
Vector graphic objects can be integrated and assigned attributes according to process
values and moved in order to display system behavior visually.
Integrating texts
Texts can be used to label operating and display elements, e.g. input/output fields or
buttons.
Displaying messages
Messages indicate events and statuses in the control process. ProTool distinguishes
between event messages and alarm messages. Event messages relate to the status of
a machine or process. Alarm messages indicate operating faults concerning a machine
or process and must be acknowledged.
Archiving process values
Windows-based systems provide the possibility of archiving process values, i.e. saving
them on a permanent basis, and evaluating them.
