Frequently Asked Questions (FAQ)

• Q: Does the FC5M-30MN-DC support electronic cam and gearing?
  A: Yes, the FC5M-30MN-DC includes electronic cam, electronic gear, and interpolation motion control functions per PLCopen standards.
• Q: What programming software works with this Flexem PLC?
  A: Use Flexem Studio (IEC61131-3 environment) supporting ladder diagram, structured text, and function block diagram.
• Q: Can I expand I/O beyond the built-in points?
  A: Absolutely. The CPU supports up to 31 expansion I/O modules, depending on the total power consumption. Add digital, analog, or temperature modules.
• Q: What is the maximum baud rate for Modbus communication?
  A: Both serial ports support baud rates from 4800 to 115200 bps, configurable via software.
• Q: Does the USB Type-C port also supply power to the PLC?
  A: No, USB is for communication only. The controller requires an external 24V DC power supply.
• Q: Is the FC5M-30MN-DC compatible with third-party HMIs?
  A: Yes, via Modbus RTU/TCP or Ethernet/IP protocols; widely used with major HMI brands.
