Heartbeat Verification
Availability
Available for the following options of feature 540 "Application Package":
• EH: Heartbeat Verifi Monitoring
• EJ: Heartbeat Verification
Device functionality checked on demand
• Verification of the correct functioning of the measuring device within specifications.
• The verification result provides information about the condition of the device:
Passed
or
Failed
.
• The results are documented in a verification report.
• The automatically generated report supports the obligation to demonstrate compliance with
internal and external regulations, laws and standards.
• Verification is possible without interrupting the process.
Advantages
• No onsite presence is required to use the function.
• The DTM
triggers verification in the device and interprets the results. No specific knowledge is
required on the part of the user.
• The verification report can be used to prove quality measures to a third party.
•
Heartbeat Verification
can replace other maintenance tasks (e.g. periodic check) or extend the
test intervals.
SIL/WHG-locked devices
• The
Heartbeat Verification
module contains a wizard for the proof test which must be performed
at appropriate intervals for the following applications:
– SIL (IEC61508/IEC61511)
– WHG (German Water Resources Act)
• To perform a proof test, the device must be locked (SIL/WHG locking).
• The wizard can be used via FieldCare, DeviceCare or a DTM-based process control system.
In the case of SIL-locked and WHG-locked devices, it is
not
possible to perform verification
without additional measures (e.g. by-passing of the output current) because the output current
must be simulated (Increased safety mode) or the level must be approached manually (Expert
mode) during subsequent re-locking (SIL/WHG locking).
