Machine Number Switch

The CPU Unit and the High-speed Counter Unit exchange data via the Special
I/O Unit Area (CIO) and the Special I/O Unit DM Area. The High-speed Counter
Unit is allocated the words for 4 Units. This means that 40 words in the Special
I/O Unit Area (CIO) and 400 words in the Special I/O Unit DM Area are allocated.
The allocation of these words is done according to the Machine Number set. The
Machine Number is set by using the two Machine Number rotary switches on the
front panel of the Unit.
Always turn OFF the power before setting the Machine Number. Use a flat-blade
screwdriver, being careful not to damage the switch. Be sure not to leave the
switch midway between settings.
Note The Machine Number determines which words in the CPU Unit's Special I/O Unit
Area (CIO 2000 to CIO 2959 and DM 20000 to DM 29599) are allocated to the
High-speed Counter Unit. Since the Unit is allocated 400 DM-words and 40 CIO-
words, the Machine Number can only be set between 00 and 92. The Machine
Numbers 93, 94 and 95 can not be set.
