Mitsubishi Ethernet Driver, OPC UA, OPC DA, Suitelink Driver
This driver is only available as part of the following TOP Server driver suites:
Channels (255 Devices Each)
PLC Series (A, ANA, Q, QnA, L, iQ-R, iQ-F)
Memory Types Supported
Native Protocol (TCP/UDP)
The Mitsubishi Ethernet driver works in conjunction with TOP Server® to provide data exchange between OPC UA, OPC DA, SuiteLink and DDE clients and Mitsubishi A and Q Series PLCs connected via the AJ71E71 or QJ71E71 family of communication cards.
The PLC built-in Ethernet Port is supported for Q and L Series devices. This driver also supports the FX3U series PLC via the FX3U-ENET Ethernet module. Data acquisition is optimized based on upstream client demand while data integrity is ensured using extensive error handling.
