6.3.5 SAMPLE program structure
Definition of subroutine
In this SAMPLE program, the user can complile subroutines from 0 to 30, and
the function of the individual subroutine is described in the subroutine library.
See below.

I/O signal processing
SAMPLE is designed to meet the different wiring on the machine tools, i.e. any
input can be connected as Normal Open, or Normal Close. All input and output
signals have been filtered by SBR62 FILTER. The I/O filtering is carried out
according to PLC MD14512[0], [1], [2], [3] and MD14512[4], [5], [6], [7].
Principle of I/O filter
with follow chart, it is easily know the correspondence of internal inputs and
outputs. Therefore in SAMPLE M100.0 is a buffered input for I0.0, and
M101.2 is for I1.2; M102.3 is for Q0.3 and M103.4 is for Q1.4, and so on. All
subroutines in LIBRARY are inputs/output independent.
