X20CM4800X - Data sheet V1.04
Various time information is available in the controller or on the network:
•System time (on the PLC, Automation PC, etc.)
•X2X Link time (for each X2X Link network)
•POWERLINK time (for each POWERLINK network)
•Time data points of I/O modules
The NetTime is based on 32-bit counters, which are increased with microsecond resolution. The sign of the time information changes after 35 min, 47 s, 483 ms and 648 µs; an overflow occurs after 71 min, 34 s, 967 ms and 296 µs.
The initialization of the times is based on the system time during the startup of the X2X Link, the I/O modules or the POWERLINK interface.
Current time information in the application can also be determined via library AsIOTime.
