Overview

Omron Fins UDP is a protocol for communication between Omron PLCs and other devices. It is a TCP/IP based protocol. The fins plugin is used for Omron PLCs with network port, such as NX1P.

Neuron supports Fins UDP protocol, which can be used to communicate with Omron PLCs through Fins UDP protocol.

.BIT

Optional, referring to a bit of an address.

.LEN[H][L]

When the data type is string type, it is a required, .LEN indicates the length of the string, including H and L two endianness, the default is H .
