Techniques
The UNIPRO Programmer
uses a step/OPCODE
approach rather than a
segment approach.
The advantages of using
OPCODES (operation
code) are:
1) only what is to be
changed is entered,
2) features can be added to older instruments,
and
3) less information needs to be saved for each
step therefore more programs can be stored.
The step approach is very similar to what an operator would
do if he were manually controlling the process.
Some of the features in the OPCODEs may not be obvious as
to how they would be used until more experience is gained.
However, with a little practice and experimentation the
Programmer can soon be mastered.
Each program in the UNIPRO consists of nineteen steps (one
OPCODE per step). Some OPCODEs allow programs to be
linked together. The UNIPRO can store up to 200 programs in
non-volatile memory.
