Channel assignments
Channel assignments used to program the mainframe are based on the switching
card type, basic channel designation, and the card location in which the card is
installed (Card 1 or Card 2).
Slot designations
When programming the Model 7002-HD, you must designate the slot depending
on the card location:
• Card 1 location: slots 1 through 5
• Card 2 location: slots 6 through 10
Channel numbers
Combining the slot number with the card channel number provides the CHANNEL
assignment for the mainframe. The slot and card channel are separated by an
exclamation point (!). For the following examples, “CHANNEL” refers to the pro-
gramming channel assignment for the mainframe, while “Channel” refers to the
channel number of the switching card.
CHANNEL 1!1 = Slot 1, Channel 1 (Card 1)
CHANNEL 4!20 = Slot 4, Channel 20 (Card 1)
CHANNEL 9!2 = Slot 9, Channel 2 (Card 2)
CHANNEL 6!36 = Slot 6, Channel 36 (Card 2)
See the card manual for details on the particular card being used.
Channel list and scan list
The Model 7002-HD can perform two basic operations: it can close and open a list
of channels, and it can scan through a list of channels. The following paragraphs
explain how to enter channels for these operations. The basic operations are
explained in
”Closing and opening channels” on page 4-9
and
.
Each operation has its own list. For basic close/open operation, channels are
entered into the channel list. For scan operation, channels are entered into the
scan list.
For basic close/open operation, the order of channels in the channel list is not
important since all listed channels will either close or open at the same time. For
scan operation, the order of channels is important. Channels will be scanned in
the order that they are presented in the scan list.
