Frequently Asked Questions
- 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 connecting FP0 to GT30 and conducting a rewriting operation in RUN mode using the “through” function, “NOT SUPPORTED” error occurs. This does not occur when using FP2. Why?
- GT30: Can I switch screens by using both the function switch and programmable controller?
- Five linked FPΣ control units communicate with a PC via RS485 at 115.2 kbps at an interval of 30ms. When operating the PC, communications sometimes stop. Communications can be restored by a power-off and on operation of FPΣ. Please explain DT90059 (serial communication error). The value is “k512”.
- If I set the data hold area of the data register, will there be any problems without a battery?
- Is the pulse count of the pulse output recorded anywhere? What is the ideal way of using FPΣ as a pulse generator for testing an external counter?
- Although the FPΣ data register was set to the data hold mode, the data changed when the power was turned on. Why? (The data was held when the power-off time was five to ten minutes.)
- What are the part numbers for the connectors used in the power supplies of FP0 and FPΣ?
- I’m planning to program FPΣ using loop and label instructions. What is the longest allowable scanning time that does not cause the WDT (watchdog timer) to time out?
- When connecting FP0 to GT30 and conducting a rewriting operation in RUN mode using the “through” function, “NOT SUPPORTED” error occurs. This does not occur when using FP2. Why?
- I changed high-level instruction F168 in the positioning program for FP0 into F171. However, an operation error occurs.
