native Temp_Close(temp);
Closes the PT100/1000 interface. This switches the temperature module to the mode with the lowest
energy consumption.
Parameter Explanation
temp Number of the PT100/1000 interface; is always 0 on the myDatalogEASY V3
Explanation
Return value
l
OK, if successful
l
ERROR_FEATURE_LOCKED, if the specified interface on the device is
not released
l
< OK, if another error occurs (see "Return codes for general purposes" in
chapter "Constants" on page 118).
native Temp_GetValue(temp, &value);
Reads the temperature measurement value for the specified PT100/1000 interface from the
temperature module
Parameter Explanation
temp Number of the PT100/1000 interface; is always 0 on the myDatalogEASY V3
value Variable to store the temperature measurement value to be read out. The
temperature measurement value is saved in the temperature module in [0.1°C].
Explanation
Return value
l
OK, if successful
l
ERROR_FEATURE_LOCKED, if the specified interface on the device is
not released
l
< OK, if another error occurs (see "Return codes for general purposes" in
chapter "Constants" on page 118).
native EasyV3_GetSysValues(values[TEasyV3_SysValue], len=sizeof values);
Reads the last valid values for the "Internal housing temperature" and "Air humidity in the housing" from
the system. The interval for determining these values is 10sec. and cannot be changed.
Parameter Explanation
values Structure for storing the measurement values (see "TEasyV3_SysValue" in
chapter "Arrays with symbolic indices" on page 138)
len Size (in cells) of the structure to store the measurement values - OPTIONAL
Explanation
Return value
l
Size (in cells) of the structure used to store the measurement values
l
ERROR, if one of the following errors occurs
