Error and solution
* 1 "SNTP OPE. ERROR" (error code: 2710) is stored in the error log only when the time setting at
power-ON or reset has failed.
For results in the case of executing the time setting regularly or by special relay "SM1270" from
the sequence program, check the SNTP status screen or special register "SD1270".
POINT
Because the error log is battery backed up, the information is retained even if the
power is turned off.
Note that the latch data backup function (to the standard ROM) cannot back up
the error log to the standard ROM.
