GSK980TC3 PLC is shown below:
Table 1-1-1
1.2 What is a Sequence Program
The programming is performed a logic control to the machine tool and its relative equipments, which
is called sequence programming.
After the programming is converted into some kind of format, CPU can be performed the code and
calculation treatment for it, and its fruits can be memorized to RAM. CPU can be rapidly read each
code stored in the memory, which can be performed the programming according to the calculation
operation.
The compiling of the sequence programming starts with developing of the ladder diagram.
