1.3.5 Checking Sequence Program
After writing the sequence program in the flash ROM, check the
sequence program.
The sequence program can be checked in the following two ways:
(1) Checking with a simulator
Connect a simulator (consisting of lamps and switches) instead of
the machine. Instead of using input signals from the machine, turn
the switches on and off to input signals, and confirm output
signals by checking the on/off states of the lamps.
(2) Checking by system operation
Connect the machine to make checks. Before starting the
operation, take safety measures because when the sequence
program is executed for the first time, an unpredictable motion
can occur.
1.3.6 Storage and Management of Sequence Program
When the sequence program is completed after checking, it should be
stored and managed by the machine tool builder.
The sequence program can be output to the printer in a ladder diagram
form by using the PC programmer.
The output ladder diagram should be attached as a maintenance
drawing to the machine together with other attached materials such as a
power magnetic cabinet circuit diagram.
