CLOSE <channel_address>[,<channel_address>,<channel_address>...]
Close one or more channels on the non digital I/O (DIO) modules. It can
also be used to “clear” bits on the digital I/O modules. The CLOSE
command does not open any channels/bits that were previously closed.
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.
Several channels or bits can be closed with one CLOSE command by
separating the channel or bit addresses with a comma. If more than one
channel or bit is specified, they are closed or bits “cleared” in the order
listed.
When CLOSE is used with the DIO modules (44474A, N2263A, N2264A,
N2265A), the DIO modules must be in either default Static Mode #1 or
Static Mode #2. Using the CLOSE command in any other mode will cause
an error. In these modes there is no read or write handshaking. Digital
modes are described in more detail on page 86.
The bits 091-094 on the 4-bit built-in digital I/O can be also included in
the channel_address.
All the channels/bits in the plug-in modules are opened following a reset.
For the DIO modules, all bits are operating as input bits, no
handshaking enabled.
