Energy Storage and Display Behavior
Internal capacitors preserve screen data during brief power dips. The Siemens 6ES5393-0UA12 maintains the last displayed values for up to 5 ms. This storage prevents screen flicker during short interruptions. The unit clears the display after a power failure longer than 5 ms.
Communication and PLC Compatibility
You connect this panel to S5 CPUs via the AS511 interface. The Siemens 6ES5393-0UA12 works with S5-95U, S5-115U, and S5-135U models. The 15-pin D-sub connector requires a shielded cable up to 15 meters. The panel polls the CPU for data updates every 200 ms.
Configuration and Programming
You program the Siemens 6ES5393-0UA12 using ProTool software. Define display texts and alarm messages in the configuration file. Assign function keys to specific data blocks and flags. The panel stores all configuration data in its internal EEPROM. Therefore, you lose no settings after power cycles.
