Polytron 7000 Operation via PROFIBUS PA
For the Polytron 7000 PROFIBUS PA transmitter, a GSD file and a DD file (for the SIMATIC PDM) are available.
For the Polytron 7000, a DTM is also available.
Use the Polytron 7xxx PROFIBUS PA Manual for configuration and commissioning the Polytron 7000.
The manual is available for free download under: http://www.draeger.com
Structure of primary value:
Primary value PROFIBUS PA and Foundation Fieldbus:
description: quality sub-status limit value
bits:
7 6 5 4 3 2 1 0
PRIMARY_VALUE Quality – The quality used will be determined by highest priority condition
Value
Bit 7, 6
Name Description
0 Bad The value is not useful
1 Uncertain The quality of the value is less than normal, but the value may still be useful.
2 Good (Non-cascade The quality of the value is good. Possible alarm conditions may be indicated by the
sub-status. Alarm indication is applies only to the PV and primary output parameters
not in the cascade path.
3 Good (Cascade) The value may be used in control.
BAD sub-status
Value
Bit 5, 4, 3, 2
Name Description
0 Non-specific There is no specific reason why the value is bad. Used for propagation.
1 Configuration Error Set if the value is not useful because there is some other problem with the block,
depending on what specific manufacturer can detect.
2 Not Connected Set if this input is not referenced in by a link object within the resource.
3 Device Failure Set if the source of the value is affected by a device failure.
4 Sensor Failure Set if the device can determine this condition. The Limits define which direction has
been exceeded.
5 No Communication, with
last usable value
Set if this value had been set by communication, which has now failed.
6 No Communication, with
no usable value
Set if there has never been any communication with this value since it was last Out of
Service.
7 Out of Service The value is not reliable because the block is not being evaluated, and may be under
construction by a configurer. Set if the block mode is O/S.
