Deltabar PMD75B PROFINET with Ethernet-APL System integration
Endress+Hauser 43
Binary Output module
The Binary Output module can cyclically receive discrete output values from the
automation system. The device implements an 8-bit type as described in PA PROFILE 4.0x.
Of this, 1 bit is used to signal to the device that Heartbeat Verification should be started.

Binary Input module
The Binary Input module can cyclically send discrete values from the device to the
automation system. In the device, the status of the Heartbeat Verification is transmitted:
Bit Function Description
0 Status
Not done
Verification not performed
1 Status
Failed
Verification failed. At least one test group was outside
the specifications.
2 Status
Busy
Verification in progress
3 Status
Done
Verification performed
4 Verification result
Failed
Verification failed. At least one test group is outside
the specifications.
5 Verification result
Passed
The device has passed the verification. All the verified
test groups met the specifications.
6 The verification result is also "Passed" if the result
for an individual test group is "Failed" and the
result for all other test groups is "Passed".
7 Verification result
Not done
Verification not performed
8.3.3 Status coding
Status Coding (hex) Meaning
BAD - Maintenance alarm 0x24 No measured value available, as a device error has occurred.
BAD - Process related 0x28 No measured value available, as the process conditions are not within the
device's technical specification limits.
BAD - Function check 0x3C A function check is active (e.g. cleaning or calibration)
UNCERTAIN - Initial value 0x4F A predefined value is output until a correct measured value is available
again or corrective measures have been performed that change this
status.
UNCERTAIN - Maintenance
demanded
0x68 Wear and tear has been detected. Maintenance is needed shortly to
ensure the device remains operational.
The measured value might be invalid. The use of the measured value
depends on the application.
UNCERTAIN - Process related 0x78 The process conditions are not within the device's technical specification
limits. This could have a negative impact on the quality and accuracy of
the measured value.
The use of the measured value depends on the application.
GOOD - OK 0x80 No error has been diagnosed.
