Frequently Asked Questions
- Module ERR indicator stays solid on and communication fails.Troubleshooting:① Poor backplane contact — Reinsert the module firmly.② Abnormal power supply — Check the output of the redundant power supply.③ Corrupted firmware — Re-flash the firmware.④ Incorrect configuration — Restore factory defaults and reconfigure.
- Ethernet connection fails and the web page cannot be accessed.Troubleshooting:① IP address conflict — Modify the module IP.② Defective network cable — Replace the cable.③ Firewall interception — Disable the PC firewall.④ Damaged port — Switch to the spare Ethernet port (if available).
- Modbus serial port packet loss and garbled data.Troubleshooting:① Mismatched baud rate / parity bit — Unify parameters of master and slave stations.② Wrong wiring — Reversed positive and negative poles on RS485.③ Severe electromagnetic interference — Add shielding layer and terminal resistor.④ Slave address conflict — Modify the slave station address.
- Time synchronization failure and chaotic system time.Troubleshooting:① Incorrect NTP server address — Verify the server IP.② Network disconnection — Check Ethernet connection.③ Faulty clock module — Replace the 560RTC0x module.④ Wrong time zone — Set to the correct time zone (UTC+8).
- Does it support hot swapping? Will data be lost after plugging and unplugging?Answer: It supports hot swapping and does not affect the operation of other modules during replacement. Module configuration is stored in Flash, so no configuration is lost after power-off or reinsertion; settings will be loaded automatically after power-on.
- What is the maximum number of supported I/O modules?Answer: A single 560CMU02 supports up to 32 I/O modules via backplane bus expansion, meeting the I/O requirements of small and medium-sized systems.
