FAQ
Q: Are IS215VCMIH2CC and IS215VCMIH2C compatible?A: Fully compatible. As an upgraded variant of Version C, IS215VCMIH2CC shares the same firmware and hardware interfaces, allowing direct replacement.
Q: What key parameters need to be confirmed before purchasing?A: Verify the system model (Mark VI), firmware version, redundancy configuration (simplex / triple modular redundancy) and production batch to avoid compatibility issues.
Q: Does this board support certifications for overseas projects?A: Yes. It complies with CE, UL and RoHS standards and meets international power industry requirements. Relevant certification documents are available.
Q: The Fail indicator stays on after power-on. How to troubleshoot?A: ① Check the power supply of the VME slot; ② Confirm the firmware version matches the system; ③ Inspect loose connections of IONet and serial ports; ④ Check for physical damage to the board.
Q: Data packet loss occurs during redundancy switchover. How to fix it?A: ① Reconfigure redundancy synchronization parameters and ensure the main and slave boards run the same firmware version; ② Check IONet network bandwidth to prevent congestion; ③ Clean connector contacts and replace aged network cables.
Q: What does a flashing Run indicator mean during operation?A: A flashing Run light indicates abnormal data communication. First check VME bus connections, status of I/O cards and system load. Restart the board or upgrade the firmware if necessary.
Q: What is the routine maintenance cycle and required operations?A: Monthly inspection and quarterly cleaning are recommended. During inspection, check LED status and all connections. Use an anti-static brush to remove dust during cleaning. Update to the latest firmware once a year.
