Computer performance
• RCU501 performance is application dependant and governed  by process complexity, updating frequency and number of interfaced I/O. Maximum
updating frequency is 50 Hz.
• Con? guration guidelines:
1. ESD/PSD: max. 800 I/O, F&G: max. 700 I/O both at scan rate: 1 Hz
2. Process/ Automation: max. 2000 I/O, design advice: 1280 I/O both at scan rate: 1 Hz
3. Anti-surge: 3 loops, Scan rate: 50 Hz
4. Dynamic Positioning: Triple redundant DP system combined with Position Mooring. (Scan rate is adapted to signal processing and varies from 1 to 10 Hz).
