6.2 Details of functions
Caution
• Do not turn ON M8015 (Clock stop and clock setting) in the PLC main unit while the time setting function is
used. Turning ON M8015 may cause errors in the Ethernet adapter.
• Do not set the time to the PLC main unit from peripheral equipment while the time setting function is used.
Setting the time may cause errors in the Ethernet adapter.
• To use the time setting function, an SNTP server (time information server) is required on the LAN.
• A delay occurs with respect to the time as a result of the time required for communication with the SNTP
server.
Specify the closest personal computer for the SNTP server on the network.
• Communication timeout occurs 20 seconds after the time is inquired from the SNTP server (time
information server).
• If the power supply of the PLC is turned on in the RUN state when "Execute time setting at turn ON" is set
up, the RUN process and time setting will start simultaneously. If "Stop" is set up at "On-error Action", after
the PLC RUNs and executes sequence processing upon power ON, it may stop due to time setting error.
To avoid this, do not execute sequence processing until time setting has finished. Please refer to the
following example program.
Example program (In case of CH1)
*1. In case of channel 2, set to M8426.
*2. In case of channel 2, set to D8431.
