Reliable Serial Connectivity for Siemens S5 PLCs via 3964 and 3964R Protocols with RK 512 Computer Link
This driver is only available as part of the following TOP Server driver suites:
Reliable serial connectivity for Siemens S5 115U, 135U, and 155U controllers using 3964 and 3964R with RK 512 computer link support.
Supports up to 100 channels and 30 devices per channel, with practical limits based on available system resources.
Supports I, Q, F, T, C, Data Block access, and data types including Float, Long Word, BCD, and String.
Supports modem, Ethernet encapsulation, and adaptive communication features.
The Siemens S5 3964 & 3964R Serial driver enables data exchange between TOP Server® and Siemens S5 controllers over the Siemens 3964/3964R serial protocol for OPC UA, OPC DA, AVEVA SuiteLink, and DDE client applications.
This driver is intended for Siemens S5 devices that support 3964/3964R and use the RK 512 computer link program. It includes extensive error handling to help maintain data integrity over the serial link.
