Assume a Model 3722 is installed in Slot 1, a Model 3721 is installed in Slot 2 and the other 4
slots are empty. Sending the following command line over the bus:
for x=1,6 do print (slot[x].idn) end
The response would be:

Break Before Make and connecting sequentially
Break Before Make (BBM) or Make Before Break (MBB) is a user settable channel attribute.
This attribute is applicable for EMR, reed, and solid state relay cards. The same attribute setting
for BBM and MBB applies to all applicable channels in the system.
To set the rule as Break Before Make over the bus, send the following ICL command:
channel.connectrule = channel.BREAK_BEFORE_MAKE
When sequential connecting is enabled, the list of channels or analog backplane relays close
sequentially. To set the connect sequential to ON over the bus, send the following ICL
command:
channel.connectsequential = channel.ON
Both of these attributes can be set using the front panel keys. To set from the front panel, use
the following procedure as a guide:
NOTE If the Series 3700 is in remote mode (controlled over the bus) press the EXIT key to
place it in local mode to control the unit using the front panel keys.
NOTE Front panel keys are not available on all models.
1. Press the MENU key.
2. Use the wheel to scroll to the CHANNEL menu item.
3. Press the ENTER key (or the wheel) to display the CONNECT MENU.
