No. Ca: Read_Error_Counter - Siemens SIMATIC ET 200SP Manual

Using the command interface
9.4 Description of the AS-i commands
9.4.33

No. CA: Read_Error_Counter

Note
With Firmware V1.1 or higher, use data record "DS 96 Read AS-i master error counters and
status messages (FW V1.1 and higher) (Page 86)" for reading out the error counters. The
Read_AS-i_Master_Error_Counters command continues to exist for compatibility reasons.
Meaning
This command reads out error counters that concern the overall AS-i network.
If the AS-i power supply is missing, the overall device fails. This leads to all counters being
reset. The counting starts over each time the device is powered up.
For the meaning of the error counters, refer to Table "Table 8-11 Meaning of error counter
(Page 86)".
