Fault memory

The current initial fault and all other subsequent faults are residually saved in the fault memory with associated timestamp.

Additional messages for the faults are entered in the fault memory in the columns "Primary fault" and "Sub-fault". These are messages that do not directly trigger a fault response of the CS..A safety option. Essentially, these are the message "Power On" (primary fault 66 and sub-fault 100) and the message "Acknowledgment message" (primary fault 66 and sub-fault 101).

In the "Pos" column, the position of the fault is displayed. In the "Info" column, a symbol indicates the category of the fault. In the "Fault message" column, the fault number, the main fault text and the subfault 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 fault memory after synchronization; no time is displayed in the column beforehand. The "Internal fault" column is used for internal purposes. The fault memory is organized as a ring memory. The most recently occurring fault is shown in line 0 of the list. If there are more than 50 entries, the oldest fault is overwritten.
