Saving and Deleting the Logs

6.7.2
Deleting the logs of the device in the operating state is not required. If storage capacity is no longer sufficient
for new indications, the oldest indications are automatically overwritten with new incoming events. In order
for the memory to contain information about the new faults in the future, for example, after an inspection of
the system, a deletion of the log makes sense. Resetting the logs is done separately for the various logs.
The fault record can be cleared with the DATA STORAGE > Clear Faults setting in the HMI.
The stored events can be cleared by using the DATA STORAGE > Clear Events setting in the HMI or from
Reydisp.

Before you delete the content of a log on your 7SR45 device, save the log with Reydisp Evolution on the
hard disk drive of your PC.

If the device executes an initial start, for example, after an update of the device software, the following
logs are automatically deleted:
•
Event log
•
Fault log
Back up the deletable logs using Reydisp Evolution.

General Alarm

6.7.3
General alarms are the user-defined text messages displayed on the LCD when binary inputs are mapped and
triggered.
Up to 4 general alarms of 16 characters can be configured, each triggered from one or more inputs. Each
general alarm generates an event.
If multiple alarms are activated simultaneously, then the last alarm indication is displayed on the LCD.
All the fault triggers generated by general alarms are logged in to the fault data record.
