These programming instructions require the user to be familiar with sections 1 to 8 of the operating
instructions for the respective programmable controller.
The following example shows a test assembly with the
1P
241 digital position decoder for testing
the jumper assignments and functions in an easy fashion. This test program can be also used as
the basis for an automation task to be realized.
The files of the function blocks with example together with commentary blocks in English and
French for the respective programmable controllers are located on the S5–DOS floppy disk.
