Model 7706 module
OUTPut Subsystem
Commands to perform output operations are listed in
The output subsystem is specific to the Model 7706 module. It is only available if a Model 7706 is installed.

Output subsystem commands
Command
:OUTPut
:VOLTage <NRf>, <clist>
:VOLTage? <clist>
:DIGital
:BYTE <nrf>,<clist>
:BYTE? <clist>
:WORD <nrf>,<clist>
:WORD? <clist>
Channel list parameter:
<clist> = (@SCH)
where: S = Mainframe slot number (1 or 2); CH = Switching module channel number (must be 2 digits);
Examples:
(@101) = Slot 1, Channel 1
(@101, 203) = Slot 1, Channel 1 and Slot 2, Channel 3
(@101:110) = Slot 1, Channels 1 through 10
:OUTPut
As mentioned in
Table
3, Channels 21 and 22 are eight-bit digital output channels, and Channels 23 and 24 are analog output
channels with a range of -12V to +12V. For individual digital channels, the range of values allowed is 0-255, and the outputs
are set to the closest integer to the sent value. Analog outputs will accept values of -12 to +12. Attempting to use this command
with an input channel generates error –221 settings conflict.
:VOLTage <nrf>,<clist>
:VOLTage? <clist>
Use to force (or query) the analog output of the given channel[s] to the desired value. Values are rounded to the nearest mV.
(-12VDC < × < +12VDC).

NOTE
Description
Set the output of a 7706 channel.
Forces the analog output of the given analog channel[s] to the desired
values in volts from -12 to +12.
Query the present voltage for the analog output channel[s].
Path to the digital commands.
Force the digital output of the given channel[s] to the desired value
(0 < × ≤ 255) in decimal format.
Query the present bit pattern (0 < × ≤ 255) for the digital output channels.
Force the digital output of the given channel[s] to the desired value
(0 < × ≤ 65535) in decimal format.
Query the present bit pattern (0 < × ≤ 65535) for the digital output
channels (returned in decimal format).
