Omron FINS UDP

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

For the generic steps, see Create a Southbound Driver and Groups and Tags.

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

W	All types except uint8/int8	read/write	Work Area
H	All types except uint8/int8	read/write	Holding Area
D	All types except uint8/int8	read/write	Data Memory Area
P	All types except uint8/int8, but bit only supports read	read/write	PVs
F	int8/uint8	read	Flag Area
EM	All types except uint8/int8	read/write	Extended Memory

Example:

Address	Data Type	Description
F0	uint8	F area, address is 0
F1	int8	F area, address is 1
CIO1	int16	CIO area, address is 1
CIO2	uint16	CIO area, address is 2
A2	int32	A area, address is 2
A4	uint32	A area, address is 4
W5	float	W area, address is 5
W10	float	W area, address is 10
H20	double	H area, address is 20
H30	uint32	H area, address is 30
D10	int32	D area, address is 10
D20	float	D area, address is 20
EM10W100	float	EM10 area, address is 100

.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 .
