Error memory
The current initial error and all other subsequent errors are residually saved in the error memory with associated timestamp.

Additional messages for the errors are entered in the error memory in the columns "Primary error" and "Suberror". These are messages that do not directly trigger an error response of the CS..A safety option. Essentially, these are the message "Power On" (primary error 66 and suberror 100) and the message "Acknowledgment message" (primary error 66 and suberror 101).
In the "Pos" column, the position of the error is displayed. In the "Info" column, a symbol indicates the category of the error. In the "Error message" column, the error number, the main error text and the suberror text is displayed. The timestamp is entered twice in the list. Once as an operating hours counter and once as system time. The system time is a time synchronized by the controller and is based on the Universal Time Coordinated (UTC). The user can set the time from UTC to local time in the controller. The system time is recorded in the error memory after synchronization; no time is displayed in the column beforehand. The "Internal error" column is used for internal purposes. The error memory is organized as a ring memory. The most recently occurring error is shown in line 0 of the list. If there are more than 50 entries, the oldest error is overwritten.
