Now with
xUseSafeStateBeforeInit:FIRST the SafeState is set as output
THEN the values are read in

Bug fixes
H1_8AI: Malfunction when updating analog inputs. It occurred that an input that actually had 0V displayed 1V. The query for the "last change" was faulty and has been corrected in this version.
1.0.2.2 - HVACModbusIO2 CODESYS 3.5.17.2 - Download
Release Date 04.09.2023
New features and changes
Update of the dependency library from ModbusFB
4.2.0.0to4.3.0.0
Bug fixes
H1_8AO: When using analog outputs, when changing TwoPointFunction (converter) parameters, the value was not transmitted. This is now fixed and the values are transmitted directly accordingly without the outputs needing to be rewritten.
H1_8DO/H1_8DOR and H1_4DIOR: Digital outputs are now written directly, even if the output is only scheduled for one cycle. Previously state changes were not observed and it could happen that an output was not written. It is strongly recommended to use this version or a newer version.
