Overview
•They are used to link data between PLCs connected to each network.
•The PLC link function is used to share and transmit exclusive internal relays “link relays (L)”
and data registers “link registers (LD)” between PLCs cyclically. For MEWNET-W2, internal
relays (WR) and data registers (DT) can be specified as well as link relays (L) and link
registers (LD).
•With the data transfer function, data can be transferred from a specified arbitrary source to
arbitrary destination by executing the SEND/RECV instructions with user programs.
•Also, monitoring or programming destination PLCs can also be possible via network.
•Either MEWNET-W or MEWNET-W2 can be used in the same network. They are selected
by the switches of the FP7 MW Unit.

(Note 1): For MEWNET-W2, the transmission distance depends on the setting of baud rate. The baud rate is set by
the mode setting switches of the unit.
Example of application
They are used when using the following Panasonic PLCs and link function.
•FP7 (Using FP7 MW Unit)
•FP2/FP2SH (Using FP2 MW Unit)
Note) MEWNET-W can also be connected to the conventional models FP3/FP10SH (discontinued products) with the
MEWNET-W link function.

ⓑSlave station ②FP I/O terminal board ③FP I/O terminal unit
Overview
•A remote I/O system in which the FP7 is applied as a master unit can be established. I/O in
a remote place can be controlled via a two-wire cable so that saving wiring, reducing man-
hours and saving space is achievable.
•Up to 32 slave units, or 4096 I/O points can be controlled per FP7 MW Unit.
•The I/O of slave units can be treated as external input (X) and external output (Y) as well as
general I/O devices.

Example of application
The remote I/O control can be performed by connecting slave units compliant with Panasonic
MEWNET-F.
•FP I/O terminal board
•FP I/O terminal unit
(Note): It cannot be connected to FP2 Slave Unit or FP3 Slave Unit (discontinued products).

1.3 Function Overview
1.3.1 PLC Link (MEWNET-W / MEWNET-W2)
Overview of Function
•The PLC link function is a communication function which enables data sharing between
PLCs easily using link relays (L) and link registers (LD) transmitted cyclically.
•For MEWNET-F, data of link relays (1008 points) and link registers (128 words) can be
converted between max. 16 PLC units.
•For MEWNET-W2, data of link relays (4,096 points) and link registers (4,096 words) can be
converted between max. 32 PLC units. Also, internal relays (WR) and data registers (DT)
can be specified as well as link relays (L) and link registers (LD).
•Send area and receive area can be allocated for each PLC connected to the network. They
are set from the configuration menu of tool software.
Example of PLC link allocation
•Either one of MEWNET-W and MEWNET-W2 can be used in the same network. It is
selected by the switch on the FP7 MW Unit.

1.3 Function Overview
1-9
Role of link relays and link registers
•If the link relay contact for one PLC goes on, the same link relay also goes on in each of the
other PLCs connected to the network.
•Likewise, if the value of a link register in one PLC is changed, the values of the same link
register are changed in all PLCs on the same network.

1.3.2 Data Transfer (MEWNT-W / MEWNET-W2)
•With the data transfer function, data can be transferred from a specified arbitrary source to
arbitrary destination by executing the SEND/RECV instructions with user programs.
•Destination PLCs need no program for sending/receiving data.
