Fig. 4.2: Module Identifier words
At the address Base + % FA the two particular bytes allow the automatic localization of the module.
For the Mod. V560 the word at address Base + % FC has the following configuration:
Manufacturer N°=
000010 b
Type of module =
0000011000 b
The word located at the address Base + %FE identifies the single module through the module's
serial number and any change in the hardware, (for example the use of faster logic) will be shown by
the Version number.
