- Product overview:
- MELSEC iQ-R series programmable controllers manufactured by Mitsubishi Electronic are available for building the 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 different manufacturers, providing control and monitoring.
- Merit.1
- Easy system start-up:The module supports the functions of Mitsubishi Electric GX Works3, making users' programming easier.
- Merit.2
- Two types of communication functions to match the application:Data communications on FL-net (OPCN-2) are performed by either cyclic transmission or message transmission.
- Merit.3
- Masterless and large-scale network:Masterless method enables users to connect/disconnect each node to/from the network at any time without affecting communications of other nodes.
Users can freely power on/off any node, and perform maintenance and connect a maximum of 254 devices.
* Of the 254 modules, 249 can be used for control. The remaining five modules are assingned for failure diagnosis
