5.2 Device Diagnostics
Note: It is mandatory and recommended to take all the diag-
nostic Inputs of the DeviceNet Device into account.
5.2.1 Common Inputs
cycleCounter: DeviceNet-FW increments this counter once after each cycle
error: indicates the number of boxes with a BoxState unequal zero
actualCycleTime: reserved for future use
DiagFlag: Shows whether the diagnostics information on the card has changed. This can be read off
using ADS Read. For that purpose, specify the net ID of the FC520x / CX1500-x520, the port number 200
and the IndexGroup 0xF100. The IndexOffset and the length then relate to the diagnostic data.
CycleFailedCounter: This counter increments each time when at the beginning of theTwinCAT-Cycle
the last Bus-Cycle was not finished
