What is the Siemens S5 Driver?

The Siemens S5 Driver provides a reliable way to connect Siemens S5 (AS511) devices to client applications;including HMI, SCADA, Historian, MES, ERP, and countless custom applications. It is intended for use with Siemens S5 PLCs communicating via the front programming port using AS511 protocol (which is specific for each Siemens device). This driver has been designed to operate with a set range of Siemens equipment: it is not recommended for use on devices that are not supported.

The Siemens S5 PLC family has a unique memory structure. Data within the PLC is not at fixed locations within the PLC’s memory space. As the PLC logic is created and modified, this memory space is continuously updated and revised. When these revisions occur, the location of the key data elements (such as flags, timers, counters, I/O, and data blocks) can move around in the PLC’s memory. The Siemens S5 Driver has been designed to read the location of these memory elements when the driver begins operation or detects a communications error. If the PLC configuration changes, users must restart the Siemens S5 Driver or pull and replace the cable connection. Both of these actions cause the driver to reacquire the location of all PLC memory elements.

Ethernet Encapsulation
This driver supports Ethernet Encapsulation, which allows communications with serial devices attached to an Ethernet network using a terminal server or device server. It may be invoked through COM ID in Channel Properties. When used directly with a serial port, this driver only supports a single connection to a single controller per serial port. When operating in Ethernet Encapsulation Mode, the driver supports up to 30 controllers per channel. In this mode, a single controller can be paired with a terminal server/device server to form a single node. For more information, refer to the server’s help documentation.
Note: The Siemens S5 AS511 protocol is sensitive to timing and gaps in the communications stream. If the network experiences heavy packet loss or delay while using Ethernet Encapsulation, the Siemens S5 Driver may report a large number of timeout errors or be unable to communicate. In some cases, using a switched network can help reduce these delays; however, it is not a guaranteed solution.

The maximum number of channels supported by this driver is 100. The maximum number of devices supported is 32.

Popular Products Series


SINAMICS G130 chassis units have been designed for variable-speed drives in machine building and plant construction.
They have been specially tuned to the requirements of drives with quadratic or constant load characteristics with medium performance requirements without regenerative feedback.

Mitsubishi F740 Series Frequency Inverter

The FR-F700 Series was launched in 2004 as the successor to the FR-F500 Series VFD. With growing market demands for energy saving inverters in building automation, water processing and HVAC industries, the FR-F700 was able to exceed power-saving expectations in fan and pump applications by incorporating “OEC” (optimum excitation control) which combined maximum drive utilization with minimal power consumption.


We provide the assembled version of 6RM80 product, and all the accessories are from the official Siemens, which are 100% tested and strictly tested before delivery.

ACS800-104/-104LC – inverter module

These 3-phase inverter modules have the flexibility to fit into your own cabinets. They can be parallel connected to produce higher powers. Built-in redundancy allows you to run the drive at partial load, even when one of the modules is not operating. The inverter modules include capacitors that smooth the voltage of the DC busbars in multidrive configurations. Available as air and liquid-cooled variants.

ACS800-04 – single drive modules

The single drive modules variant ACS800-04M offers more possibilities. Including normal bookshelf mounting and flat (sideways) mounting. This improves installation into cabinets with a shallow inner depth. Frame size R7 also offers a variant with motor connections available from the bottom of the module. Giving you the possibility of a narrower cabinet for relevant installations.
