Siemens SIMATIC 6DL1 136-6AA00-0PH1 - HART Revision; Field Devices with HART Revision 5 and 6

Description
The quality code is structured as follows:
Bit 7….6 5....2 1…0
Quality
0 0: Bad
0 1: Uncertain
1 0: Good
1 1: Good
Sub-status
Coded according to "PROFIBUS PA Pro‐
󹪝le for Process Control Devices"
Limits
0 0: OK
0 1: Low limit
1 0: High limit
1 1: Constant
The quality codes generated by the I/O module conform to the HART revision of the 󹪝eld device
used.

8.4.4.1 Field devices with HART revision 5 and 6
De󹪝nition
The quality code is formed exclusively from the 1st and 2nd status byte (HART device status) of
the response frames (HART command 3).
Description
The quality code of 󹪝eld devices with HART revision 5 and 6 is structured as follows:
Quality code Meaning (process status)
80
H
Value is okay Also applies when the following bits
are set in the 2nd status byte of the
HART response frame:
• Con󹪝guration changed
• Startup (cold start)
• Fixed analog output current setting
78
H
Value is uncertain Also applies when the following bits
are set in the 2nd status byte of the
HART response frame:
• Additional status information avail‐
able
• Analog output current saturated
• Secondary variable outside the lim‐
its
• Primary variable outside the range
