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.
■
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 Function Overview
WUME-FP7MW-06 1-7
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.
1.3 Function Overview

Order of allocated I/O numbers
I/O numbers for slave units are allocated in the order of slave numbers set with the switch of
each slave unit.
I/O numbers for slave units are allocated in the order of slave numbers regardless of the
connecting order of slave units.
■
I/O numbers allocated when 8-type units are mixed
As 16-point I/Os are allocated even for an 8-point type, dead numbers occur between the unit
and a subsequent unit with the next slave number.
Example) When the I/O numbers for the 8-type slave no. 1 are X100 to X107, X108 to X10F are
dead numbers. The I/O numbers for the slave no. 2 start from X110 or Y110.
■
How to count I/O numbers for units that have both inputs and outputs
In the case of a unit that has both inputs and outputs, input numbers and output numbers start
with the same value.
Example) If input numbers for an I/O terminal board (input 16 points / output 16 points) are
X100 to X10F, the unit's output numbers are set at Y100 to Y10F.
