Siemens 6ES5393-0UA15 Operator Interface

The Siemens 6ES5393-0UA15 operator interface provides local monitoring for SIMATIC S5 control systems. This panel displays machine status and allows parameter adjustments for industrial processes. It connects directly to the S5 CPU via the AS511 programming port. You can use this panel as a direct replacement for older OP units.

Detailed Technical Specifications

The Siemens 6ES5393-0UA15 operator interface measures 138 mm in width. Its height reaches 68 mm across the front panel. The total depth goes up to 40 mm including the rear connector. This unit weighs approximately 0.38 kilograms for panel mounting.

Key hardware parameters include:

Complete Model: Siemens 6ES5393-0UA15
Display type: LCD with green LED backlight
Display format: 2 lines x 20 characters per line
Character height: 5.5 mm for clear visibility
Keypad: 12 tactile membrane keys
Interface: AS511 serial (TTL level)
Connector: 9-pin SUB-D female
Power supply: 24 V DC nominal (18-30 V range)

Application and Installation

The Siemens 6ES5393-0UA15 operator interface mounts into a standard 138 mm x 68 mm panel cutout. It requires a 4-core cable for connection to the CPU’s AS511 port. This panel displays timer values, counter readings, and fault messages. Consequently, operators can monitor key production data without a programming device.

Programming and Operation

This interface uses simple function calls from the S5 program. The Siemens 6ES5393-0UA15 stores pre-defined texts in its internal EEPROM. You can trigger messages using standard system function blocks (SFB 31 and SFB 32). Therefore, programming text displays requires minimal code in your existing logic.

Always power down the CPU before connecting or disconnecting this panel. Match the interface cable wiring to the pinout diagram carefully. The unit features a removable terminal block for power wiring. Furthermore, its IP40 membrane keypad resists dust and light splashes.
