Question: What does the error 400DE mean when using Citect with RSLinx? 

The error code 400DE is the error "Not in Database". This is usually caused by not configuring the Client Application in RSLinx.

To configure the Client Application in RSLinx:

  1. Go to Communications | Configure Client Applications
  2. In the Interchange Port Mapping configure port 1KT:0 (which is the first KT card) to be AB_KT-1.
    AB_KT-1 is the Driver configured in RSLinx under Communication | Configure Drivers
