MELSEC iQ-R series products manufactured by Mitsubishi are available for constructing an FL-net (OPCN-2) system.
The FL-net (OPCN-2) can be interconnected to devices such as programmable controllers,computerized numerical controllers (CNC),
and personal computers which are manufactured by various manufacturers,providing control and monitoring.
FL-net (OPCN-2) Interface module ER-1FL2-T
FL-net system with MELSEC iQ-R series products
Overview
- Common memory function that uses cyclic transmission to allow each node to always share the same data
- Message communication function that allows only the required data to be exchanged when needed
- Event history
- Module diagnostics
- Intelligent function module monitor
- Module label
- Module FB (Function block)
In addition, the nodes can be powered on/off or maintained freely, and a maximum of 254 modules (*1) can be connected to the network.
*1 Of the 254 modules, 249 can be used for control.The remaining five modules are assigned for failure diagnosis.
