When using a driver in mode Simulation - programmed, in the zenon runtime an empty string of a variable of type string can`t be read when setting an empty string via the zenon logic workbench.
Summary
An empty string can`t be read in the zenon runtime when using a driver in mode Simulation - programmed and setting an empty string via the zenon logic workbench. Therefore in the zenon runtime the string variable still shows the prior string value although an empty string has been set via the zenon logic workbench.
Description
An empty string can`t be read in the zenon runtime when using a driver in mode Simulation - programmed and setting an empty string via the zenon logic workbench. Therefore in the zenon runtime the string variable still shows the prior string value although an empty string has been set via the zenon logic workbench.
Solution
This issue has been addressed by improving the way the the length of a string is determined.
