The basics on how to write a program are given in the Programming the PLC chapter while a small, but
still powerful, user interface for the PLC is described in the PLC Console chapter.
Thorough information on how to use the Multiprog wt environment for editing PLC programs is given in
"The PowerMACS PLC Manual [2].
