S-Bus communication stops when S-Bus communication library 2.7.370 or E-Line S-Bus communication library < 1.2.110 was used and the communication mode ‘on Event’ or ‘on Sampling time n’ has been selected on the S-Bus communication FBoxes

Due to an error on the S-Bus communication library 2.7.370 and the E-Line S-Bus communication library < 1.2.110, the S-Bus communication stops after a certain time or after download of the program, if the communication mode ‘on Event’ or ‘on Sampling time n’ has been selected on the S-Bus communication FBoxes.

To solve the issue, either configure the communication mode in the ‘old’ FBox to ‘On each cycle’ or ‘on data change’ or use the E-Line S-Bus communication library 1.2.110 and the S-Bus communication library 2.7.380 or newer ones.
