The zenon runtime shows unexpected behaviour when a high amount of value changes of variables of the Modbus Process Gateway (AccessMODBUS) take place. This is the case when in addition to the value changes also the number of variables which the Modbus Process Gateway contains is very high.
Summary
When the Modbus Process gateway (AccessMODBUS) contains a high amount of variables and the values of these are changing very fast, the zenon runtime behaves unexpectedly.
Description
When the Modbus Process gateway (AccessMODBUS) contains a high amount of variables and the values of these are changing very fast, the zenon runtime behaves unexpectedly.
Solution
This issue has been addressed by improving the processing of value changes between the zenon runtime and the Modbus Process Gateway and the other way round.
Information
Also other components of the zenon runtime, e. g. drivers, can show unexpected behaviour in this scenario.
