Time Synchronization (PLCTimeSync)
The CPU 41x-2 PCI can be synchronized, together with other nodes (for example,
S7 components) with a central time-of-day transmitter.
The time synchronization service in the PC supplies the CPU at intervals with the
current date and time. The time-of-day transmitter furnishes the time of day at
periodic intervals on the Industrial Ethernet or PROFIBUS (IE/PB). Only the ISO
protocol is supported by Industrial Ethernet.
