To Close a Channel
On the multiplexer and switch modules, you can close and open individual
relays on the module. However, note that if you have already configured
any multiplexer channels for scanning, you cannot independently close
and open individual relays on that module.
1 Select the channel.
Turn the knob until the desired channel is shown on the right side of
front-panel display. For this example, select channel 213.
2 Close the selected channel.
3 Open the selected channel.
Note: will sequentially open all channels on the module in the
selected slot.
The table below shows the low-level control operations available for each
of the plug-in modules.
