Working Principle The VCMI card operates as the master controller for the IONet communication network. It continuously polls all connected terminal boards to read input status and write output commands. The card maintains a real-time database of all I/O points, which is accessed by the main processor through the VME bus. It handles network arbitration, error detection, and automatic retry mechanisms to ensure reliable data transfer. The card also manages system-wide time synchronization, ensuring all control actions are properly coordinated.
