Serial interface COM1
The serial interface COM1 is no longer available.
Programming can be performed via the serial interface COM2.
Serial interface The serial interface DIAG is used for diagnosis and configuration. The DIAG interface is not
DIAG electrically isolated and thus only intended for connection with the Automation Builder.
In the CPU or Automation Builder, the DIAG interface is accessed via the FBP interface. Conse-
quently, the information of the DIAG interface appears on the CPU display under the FBP inter-
face.
