Process data (only EL9210)
The EL 9210 has a bit width of 2 bits (diagnosis bit for the power contacts voltage, "PowerOK" and diagnosis
bit for fuse error, "FuseError") and is displayed in the TwinCAT tree as follows:
Fig. 30: EL9210 in the TwinCAT tree
If there is no voltage impressed on the power contacts, the corresponding diagnosis bit 'PowerOK' has
FALSE (0) status.
If there is a fuse error, the corresponding diagnosis bit 'FuseError' has TRUE (1) status.
