Hi I have tried with these scripts but Still we are facing issues, While switching the connection CPUA to CPUB tags are not communicating. The JAVAscripts works fine. But for testing the redundancy, We have removed the CPUB cable, after removing it is not working. I will attach the screenshots we have done so far Attachment HMI_Connection script.zip (479 Downloads)
