Siemens 6ES5318-8MB13 Interface Module

The 6ES5318-8MB13 serves as an interface module for AS-Interface networks in S5 systems. This unit connects AS-Interface slaves to the SIMATIC S5 controller. Its rectangular frame measures 232 millimeters in width. The module height reaches 210 millimeters exactly. Depth stays at 155 millimeters. You will find this unit weighs approximately 0.85 kilograms. Therefore, installation requires sliding the module into a standard S5 rack slot. One front connector handles all AS-Interface wiring connections.

Physical Layout and Connectors

The front connector accepts wires up to 14 AWG gauge. A green LED indicates power present on the module. Four status LEDs show network activity and error conditions. Two guide rails secure the module firmly in the rack. A rotary switch allows manual address setting for the master.

Internal Design and Energy Storage

The 6ES5318-8MB13 contains exactly 268 discrete components onboard. A 680 microfarad capacitor bank filters the internal power supply. An AS-Interface master chip handles all network communication protocols. The module includes galvanic isolation for the network interface. LED indicators show configuration and error status clearly. A dedicated processor manages data exchange with the S5 backplane.

Operational Performance

This interface module communicates with up to 62 AS-Interface slaves. It reads input data from sensors and writes output data to actuators. Moreover, the unit automatically detects and configures connected slaves. You can place slaves up to 100 meters away from the master. The module supports both standard and A/B addressing modes. Four LEDs provide clear visual indication of network status. Consequently, you achieve reliable AS-Interface communication for S5 systems. Siemens designed this module for simple sensor-actuator networking. Its low-cost design reduces wiring complexity significantly.

In summary, the 6ES5318-8MB13 delivers reliable AS-Interface connectivity. Use this module for connecting sensors and actuators in S5 systems. It simplifies field wiring with a single two-wire cable. Order this interface module for your Siemens SIMATIC S5 system.
