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