Issue
When ordering a bCX1 controller (models 9640 or 4040), the number of controller nodes displayed on the options page is one more than the ordered quantity.
Product Line
Andover Continuum
Environment
- bCX1 9640
- bCX1 4040
Cause
All bCX1 controllers include one additional node beyond the ordered quantity. This extra node is reserved for connecting a RoamIO device to either the MS/TP or Infinet network.
Resolution
- The additional node is intentional and allows the RoamIO to connect to the network.
- When designing a system, always leave one node available for RoamIO.
- Example:
- An 8-node controller supports up to 9 nodes.
- A 32-node controller supports up to 33 nodes.
- If all nodes are used, offline editing may be required to add the last node.
