Clock information cannot be changed because a bus error
occurred between the PLC and the Ethernet Unit.
Turn OFF the power and restart the PLC.
If the problem occurs again, replace the PLC, Backplane, or
Ethernet Unit.
For some CPU Unit models and lots, there are operation
modes in which clock information cannot be changed.
For the following model and lot numbers, clock information
cannot be changed while using RUN Mode or Monitor Mode
in asynchronous mode.
There is a mistake in the Unit Setup. Correct the mistake.
The automatic clock adjustment function cannot be used
because no IP address or host name is set for the SNTP
server.
Using the CX-Programmer, make the SNTP settings in the
System Setup. If the host name is used for the server settings,
then the DNS tab settings must be made too.
Referring to the error log, correct the communications path.
