TYPE

Use the TYPE feature to assign a model number to each
non-701X series card installed in the mainframe. This
menu selection also allows you to assign a slot to oper-
ate as a simulator. By assigning a slot the value 9990,
the mainframe will operate as if a 40 channel multi-
plexer card is installed. If you assign a slot the value
9991, the mainframe will operate as if a 4 x 10 matrix
card is installed in that slot. These simulators allow you
to develop a test program even though the card is not
installed in the mainframe.

The TYPE menu selection displays an assignment mes-
sage for each slot. These messages were determined by
the Model 7001 mainframe during its power-up se-
quence and is explained in paragraph 4.2.3. In general,
the Model 7001 mainframe detects (on power-up)
Model 701X series cards that are installed. All other
type cards are not detected and thus, the slot must be
assigned the appropriate model number by the user.
This user assigned model number is "remembered" by
the mainframe after it is turned off. However, if the
mainframe detects a 701X series card in the slot on the
subsequent power-up, it disregards the model number
assigned by the user and assigns the model number of
the 701X series card to the slot. You can use Table 4-5 to
interpret the displayed messages for TYPE.
Each used slot must be assigned the correct model
number (either automatically by the mainframe for
701X series cards or manually by the user) in order for
the mainframe to operate correctly. The model number
assignment automatically determines the settling time
for the relays.
Changing a slot assignment (Card TYPE) could make a
channel that is currently included in the Scan List and/
or a Channel Pattern unavailable. The unavailable
channel causes the Scan List and/or the affected Chan-
nel Pattern to clear (see paragraphs 4.5.2 and 4.5.5 for
details).
