1. Generating a basic flow chart
A basic flow chart is very important in generating a PLC program as it acts as a
draft of PLC program. A flow chart normally composed of ‘Process’, ‘Decision’,
‘Batch’ etc. The more detail the flow chart, the easier to do the later processes.
‘Process’ can’t be activated if the ‘Decision’ is not fulfilled. The following is the
flow chart of the simplified design. Details of the flow chart will not be explained.
The basic flow chart can affect significantly the later diagram like sequential
table and PLC program. It’s beneficial to approve that the flow chart contain at least
significant errors as possible.
