Hi. I have a supervisor project running V1.1, with a database connection to ms-access. Sometimes the data is not stored in database. It should be stored every time a bit from the PLC is ON (CJ1M-CPU11), the bit is ON for 5 sec. and the point is updated every 2 sec. Here is my question, can the be the antivirus program on the computer using all capacity, so there is sometimes not enough for logging data.
