Issue
When you order a bCX1 (Both 9640 and 4040) the number of controller nodes shown in the options page is 1 more that the ordered part.
Environment
bCX1 9640 & 4040
Cause
When you order an 8 node controller it will support up to 9 nodes
32 node controllers support up to 33 nodes etc
Resolution
All bCX1 controllers are shipped with an additional node to allow for the RoamIO to be used on either their MS/TP or Infinet network.
The RoamIO uses 1 node to connect to the network.
When designing a system 1 additional node should always be left available for the RoamIO to be connected.
At times it may be necessary to offline edit to add the last (8th) node
