Time setting function

The Ethernet adapter collects time information from a time information server connected to LAN (SNTP
server), making it possible to set the PLC main unit time automatically.
The time setting function queries the time information server to ask the time at the specified timing.
Also, it sets the time sent from the time information server as clock data of the main unit.
The time setting operation is executed based on the following timing.
• At PLC main unit power ON.
• Execution at a specified time interval (Execution interval)
• Execution at a specified time (Execution time)
• At special auxiliary relay ON.
*1. The time setting function is valid when the special M bit (CH1: M8411, CH2: M8431) is ON. For details
of the special M bit, refer to Appendix A.
For operation of GX Works2, refer to Section 8.3.
