Reliable Current Loop Connectivity via the S5 PLC Programming Port - Legacy AS511 Protocol
This driver is only available as part of the following TOP Server driver suites:
Connect Siemens S5 controllers across multiple CPU families
Up to 100 channels and 30 devices per channel
Supports all memory types and industrial data formats
Serial, modem, and Ethernet encapsulation support
The Siemens S5 AS511 driver works in conjunction with TOP Server® to provide data exchange between OPC UA, OPC DA, AVEVA SuiteLink and DDE clients and Siemens S5 controllers via the Siemens AS511 Current Loop serial protocol.
This driver allows a direct connection to the programming port of the S5 PLC using a Current Loop connection. It requires the use of either the supplied Siemens programming cable or an external RS-232 to Current Loop converter. Extensive error handling helps ensure data integrity across the legacy serial link.
Important Notes:
Proven benefits for legacy Siemens S5 modernization via the AS511 programming port
Automatic Tag Database Generation using CSV Import
Tag configuration supports dynamic tags from your client application
Memory Types Supported: I, Q, F, T, C, and Data Block Access by named type
Supports all memory types and data types such as Float, Long Word, and BCD
String support includes address modifiers to specify byte order
Supports multiple PLC connections when using Ethernet Encapsulation
Auto Device Demotion Support to optimize communication with responsive devices
Communication Serialization (Virtual Networks allow multi-protocol support on the same communication channel for telemetry scenarios)
Reads the location of memory elements when the driver begins operation or detects a communications errors
NOTE: 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.
"The Software Toolbox support team was very helpful and provided lots of useful advice and links to help me solve my issue."
