6.2 Important settings at the device

6.2.1 Basic settings/operating modes

• ATA operating mode: Recommendation for stand-alone applications: stack memory

Recommendation for cyclic serial PC read-out: ring memory

•Encryption: On

•Cover: Checking

Note: After commissioning and qualification of the expected device functions/system validation,

cover the rear of the device with a terminal cover/rearside cover. The presence of the cover can

be automatically detected by means of the contact pin (setting see above).

When the cover is on/detected, even the administrator cannot make any more changes to the

set-up.

Exception: When the cover is on, text picklists can be used and administration carried out by

the logged-in administrator only. However, processes already saved are not altered.

Recommended: Seal the screws of the cover with lead. This provides practical, effective protec-

tion against manipulation/unauthorised access.

• ATAFlash change: If cyclic serial PC read-out is not activated, the warning on ATAFlash change

must be activated

Æ Basic settings Æ ATAFlash change Æ Acknowledge warn: yes

6.2.2 Signal settings/digital outputs

• Relay 1 in LV: Opening + divert

Note: With this setting, current passes through the coil of relay 1 in normal mode, the relay picks

up (creates contact between terminals 41 and 44). If the power fails and/or – if assigned in a limit

value situation – the current is switched off, the relay drops out and creates contact between ter-

minals 41 and 42. In this way, a power failure, for example, can be reliably reported
