Hello PLC0709; You will find information on time synchronization between a PLC and an HMI using area pointers in the pdf document attached to this link: https://support.industry.siemens.com/cs/ww/en/view/69864408 You ill see 2 area pointers described: - "Date/Time", used to transfer the date and time from the HMI to the PLC. - "Date/Time PLC", used to transfer the date and time from the PLC to the HMI. It all depends on your project design, you will decide which of the HMI or the PLC will act as a time master. Hope this helps, Daniel Chartier |
