Warning and error messages

Protective functions output warning and error messages.

Warning messages are temporary. They indicate that a measured variable lies outside of the nominal operating range. The warning message is canceled if the measured variable returns to within the nominal operating range.

Error messages are persistent. They persist until they are actively reset: Resetting an error state. They also persist after a voltage reset (U_S).
A protective function signals through an error message that it has switched off at least one output voltage.

Warning messages and error messages are signaled in two ways:

• Status LEDs
• Status bits in the process data

Use the Status bits to narrow down the cause of warnings or errors.

Status bits for group errors

• "Global Error Bit"
  (input variable "DPO Inputs Device" > "Device Status").
  This status bit is set with every error message. If it is not set, there is no error message from any protective function.
• "Channel Error"
  (input variables "DPO Inputs Channel n" > "Status").
  These status bits are set with every error message that concerns the respective EtherCAT P port.

Global Status bits

Input variable: "DPO Inputs Device" > "Device Status":

Status bits per output

Input variable: "DPO Inputs Channel n" > "Status"
(n = 0 for X52, n = 1 for X53, n = 2 for X54, n = 3 for X55)
