SLIST <channel_address>[,<channel_address>,<channel_address>...]
Specifies a sequence of channels to be scanned. The sequence is specified
as a list of up to 85 channel addresses (relays or digital I/O lines) and/or
stored setups separated by commas. Contiguous channels may be
specified by entering the first channel address and the last channel
address separated by a hyphen. STEP is used to sequentially close
channels in the list.
The channel_address has the form @snn, where s is the slot number and
nn is the channel number. For all mainframes, slot 0 refers to the 3499A/
B/C control board. Valid slot numbers are:
The channel number, nn, is plug-in module dependent. Channel
numbers for plug-in modules are listed on page 70.
The 4-bit built-in DIO bits (091-094) can be included in a scan_list.
Channels may be scanned in any sequence, i.e., 309-300.
Stepping beyond the last channel specified in the scan list cause a wrap-
around to the first channel in the list. The number 0 can be used as a
stop channel.
CHAN may be used to specify a particular channel/bit to close. If CHAN is
used, any channel/bit previously closed in the scan list will open and the
channel/bit specified by CHAN will close. In addition, if the channel/bit
closed by CHAN is specified in the scan list, subsequent scanning with the
STEP command will start with that channel/bit.
The commands OPEN, CLOSE, CRESET, or RECALL will have no effect on
the scan list even though the states of individual channels change.
Stored channel setups may be recalled as part of a scan list by specifying
the register number.
