Quality byte coding of input values for process pressure and process temperature:
Status coding for "bad quality"
Dec Hex Cause Error codes and remedy
00 00 Quality status of source is bad. Depending on the PROFIBUS source the
quality status is mapped to error code E12
for temperature or E16 for pressure.
01 01 Quality status of source is bad and
temp. or pressure is low limit.
Temperature: E12 & E13
Pressure: E16 & E17
02 02 Quality status of source is bad and
temp. or pressure is high limit.
Temperature: E12 & E14
Pressure: E16 & E18
03 03 Quality status of source is bad and
temp. or pressure is constant.
Temperature: E12 & E15
Pressure: E16 & E19
Status coding for "uncertain quality"
Dec Hex Cause Error codes and remedy
64 40 Quality status of source is uncertain. Depending on the PROFIBUS source the
quality status is mapped to error code E23
for temperature or E24 for pressure.
65 41 Quality status of source is uncertain
and temp. or pressure is low limit.
Temperature: E23 & E13
Pressure: E24 & E17
66 42 Quality status of source is uncertain
and temp. or pressure is high limit.
Temperature: E23 & E14
Pressure: E24 & E18
67 43 Quality status of source is uncertain
and temp. or pressure is constant.
Temperature: E23 & E15
Pressure: E24 & E19
Status coding for "good quality"
Dec Hex Cause Error codes and remedy
128 80 Ok
129 81 Quality status of temp. or pressure is
low limit.
Depending on the PROFIBUS source the
quality status is mapped to specific error
code for temperature or pressure.
Temperature: E13
Pressure: E17
130 82 Quality status of temp. or pressure is
high limit.
Temperature: E14
Pressure: E18
131 83 Quality status of temp. or pressure is
constant.
Temperature: E15
Pressure: E19
