Program Chart - Twelve Drummers

It was now ready for powering up to enable programming of the PLC to begin (picture 9).

Alongside the building of the unit, it had also been necessary to think about and prepare a programming sequence chart of the intended sequence of animation in readiness to program the PLC. The proposed sequence of actions had been “mulled over” for some time and bit by bit developed into the chart shown (picture 10).

The left hand side covers the “12 Drummers” sequence and the right hand side the “MERRY XMAS” letters. Towards the end, the two sides combine into one integrated sequence.

The PLC program was then built up (loaded) from scratch using a PC connected to the PLC and running a software editing package that “talks” to the PLC over a serial comms link.
