Overview of PLC function
PLC (Programmable Logic Controller) software is used for configuring the Inputs/outputs
(I/Os), alarms, indications, recording and others. PLC logic consist of “timers”, “flip-flops”, and
logic gates “AND, OR, XOR, NOT”. The user can configure PLC-logic using the PLC editor
(MULTIPROG®), which should be installed in the user’s PC. Figure 7.1-1 shows the screen for
the PLC editor.
