Let PLCs capable of sending PLC-2 unsolicited messages initiate communications with TOP Server
This driver is included in the following TOP Server driver suites:
Simulate up to 16 PLC connections.
Handles up to 256 concurrent TCP connections.
Single channel architecture for simplified setup.
Fast configuration with CSV tag import.
The Rockwell Allen-Bradley Server Ethernet driver works in conjunction with TOP Server to provide data exchange between OPC UA, OPC DA, SuiteLink and DDE clients and Allen-Bradley PLCs that are capable of sending PLC-2 format unsolicited messages.
This driver acts as a simulated Allen-Bradley PLC-2 device allowing unsolicited communications between TOP Server and Allen-Bradley controllers, supporting up to 256 device connections to this simulated device. The functionality allows the server to receive data by exception from an Allen-Bradley PLC capable of PLC-2 Messaging via the Allen-Bradley Ethernet protocol.
In some applications, letting the PLC decide based on data change or other conditions when to send data to the OPC Server offers faster performance than a traditional architecture where the OPC server is polling the PLC.
We offer a similar solution for PLCs using ControlLogix/CIP Ethernet to do the same thing.
This driver does not require a Rockwell Automation RSLinx license.
This driver is available in the following TOP Server driver suites: TOP Server Allen-Bradley Suite, TOP Server Manufacturing Suite.
