7.2 DESCRIPTION OF COMMANDS
Each command consists of three parts: function,
card ID, and unit ID. [Function, Car d ID, Unit ID]
Example:
[VERC3U2]
VER = Function
C3 = Card ID
U2 = Unit ID
For detailed information regarding function, see
each command description.
Card ID is an assigned value from 1 to 19, which
represents the number of slots. Card ID 0 (C0) is
used for the controller (see user’s guide for the
MT100-100). Changing the position of a card will
significantly affect the commands recorded on
software definitions or a thir d par t y contr ol system .
Unit ID has a value from 0 to 9. Unit ID 0 should be
used for single unit operation. If the Unit ID is set t o
0, then each command can be used without Ui (use
command [SETU0]; see user’s guide for the MT100-
100).
Example:
[VERC3]: for unit ID zero
[VERC3Ui]: for unit I D ot her than zero
[VERC3]: equivalent to
