Control procedures of the pilot valves in the pneumatic block of the
positioner are counted since the last time this parameter was reset,
and displayed here.
Corresponds to the description for "Diagnostics parameters
'42.VENT1' / '43.VENT2' (Page 220)" referred to the diagnostics pa-
rameters "VEN1R" and "VEN2R" described here.

The minimum and maximum temperatures within the enclosure are
constantly determined and saved as with a slave pointer. This
value can only be reset in the factory. In order to switch over the
temperature display between °C and °F,
press the
button for at least 5 seconds in order to initiate a
save function. The values of the diagnostics parameters
"Diagnostics parameter '8.WAY' - Determined travel (Page 210)" to
"Diagnostics parameter '11.LEAK' Leakage test (Page 211)" and
"Diagnostics parameters '21.P0' Potentiometer value of bottom
end stop / '22.P100' Potentiometer value of top end stop
(Page 216)" to "Diagnostics parameters '28.SSUP' Slow step zone
UP / '29.SSDN' Slow step zone DOWN (Page 219)" are saved in
the non-volatile memory as "data of last maintenance". This diag-
nostics data contains selected values whose changes can give
information about mechanical wear and tear of the valve.
This function is normally operated through the PDM, menu com-
mand "Device-> Save maintenance info". The data of the last
maintenance operation can be compared with the current data
using SIMATIC PDM.
