Hello Fueguinhio In different FW Versions the security features of the PLC s are different, Check the security settings for secure HMI communication. Every PLC has a certificate for this. The certificate has a start and enddate. So thePLc and HMi should use the current time/date to be in the range for the certificate. So check these two FAQs: https://support.industry.siemens.com/cs/de/en/view/109803668 https://support.industry.siemens.com/cs/de/en/view/109820712 and check the security levels/settings in the PLC for HMI access bye Murof |
