Make TOP Server Look like a Logix Family PLC Memory Space
This driver is included in the following TOP Server driver suites:
Simulate up to 16 Logix controllers.
Concurrent TCP connections supported.
Rapid tag database generation.
No additional licensing required.
With this TOP Server driver, we reverse the communications and instead of polling PLCs, the TOP Server driver instance becomes a memory space you define with tagnames & structures of your choice even through mass CSV import, that ControlLogix 5000 series PLCs or SoftLogix PLCs can communicate with using CIP Data Table Read/Writes.
Examples
Proven benefits that help you deploy faster and operate more reliably
Supports Logix family controllers with firmware revision 16 or higher using unconnected messaging, as well as connected messaging for reliable communication.
Symbolic read and write operations are supported, including both fragmented and unfragmented read and write methods for flexible data handling.
Advanced symbolic tag addressing enables precise and efficient access to controller data structures.
Supports identity requests over both TCP and UDP. Communication is handled through a standard Ethernet network interface card using TCP and IP protocols.
Supports ControlLogix native tag addressing for atomic data types, including BOOL, DWORD, SINT, INT, DINT, LINT, and REAL, as well as individual atomic elements within structures.
Supports both unconnected and connected messaging. Includes unfragmented read, fragmented read, unfragmented write, fragmented write, and read modify write operations.
ODVA conformance is supported, with the ability to specify an ODVA member ID. EDS file support is included for streamlined device integration.
The driver can simulate up to 16 separate Logix CPUs, including one local and up to 15 remote instances.

Everything you need for reliable industrial connectivity
Supports 1 channel with up to 16 devices per channel.
A single TOP Server instance can appear as up to 16 different Logix family PLC memory spaces.
Supports up to 256 incoming TCP socket connections for client communications.
If the network adapter or port conflicts with another application on the host machine, the driver cannot accept inbound EtherNet IP connections.
Automatic tag database generation is available through CSV import, enabling fast and efficient setup.
Advanced error handling ensures data integrity. No Rockwell Automation RSLinx license is required.

Verified PurchaseZachary Parham was very available and very efficient.
The TOP Server demo runs as the full product for 2 hours per run. After 2 hours, simply restart the TOP Server service to reset the demo timer. Once licensed, the time limitation is removed.
