- What’s the difference between FL (file register) and DT (data register)?
- Recent notebook computers don’t have serial ports, but have USB ports only. How do I connect PLCs, such as FP0, FP1, and FP10SH to edit the programs?
- When rewriting the program, all data in the data area are reset to zero. Therefore, I tried to hold the data by using "Hold PLC Device Value" function of GT10. However, the data still became zero. How can I successfully hold the data?

- If the program which transmits / receives the data for 1024 word is created and performed, it communicates for 3 seconds, and it stops about 20 seconds, operation which repeats this is carried out, and it cannot communicate normally. Why is it? In addition, he has also assigned the transmitting buffer and receiving buffer every 1024 words, and is trying not to generate overflow.
- What will happen when the transmission byte size for the serial communication instruction (F144) is set to a negative value? When the transmission byte size is seven bytes, does the transmission data table need four words? When will the receive buffer be cleared?
