Expansion modules
The 2085 expansion modules are attached to the right side of L50E and L70E controllers to extend their capabilities. The number of supported expansion modules varies with the controller type:
- L50E controllers with less than 24 digital I/O points support up to four expansion I/O modules and up to 132 digital I/O points.
- L50E controllers with 48 digital I/O points support up to four expansion I/O modules and up to 192 digital I/O points.
- L70E controllers support up to eight expansion I/O modules if a power supply module is attached, and support up to 304 digital I/O points.
In
FactoryTalk Design Workbench
, you can configure whether to fault the controller if an expansion module is absent. To check if an expansion module is present, use the MODULE_INFO instruction.The following image shows an L70E controller configuration with three expansion modules and a power supply module. The power supply module must be in slot 2, 3, 4, or 5.
Because the L70E expansion module does not have inputs or outputs, it uses a physical slot instead of a logical slot.
L70E controller with expansion modules
After adding an analog or digital expansion module to the controller:
- Global variables are created in the controller project to support the additional I/O points.
- The module's catalog and slot number are shown inProject Organizer. To open the expansion module's configuration page, inProject Organizer, go to , and then double-click the expansion module.
