Functions and Restrictions of the
Unit
1.1 Features and Functions
FP-series remote I/O system "MEWNET-F" is an I/O control network that supports the following features.
I/O remote control with FP2/FP3
I/O information (On/Off information of contacts) can be exchanged between a CPU unit (master station)
and an I/O terminal (slave station) at a remote location. A 2-conductor communication cable is used for
the connection.
High-speed, long-distance communication of I/O information
The system can support for a total communication distance of up to 700 m (*) at a baud rate of 0.5 Mbps.
* This is the distance guaranteed when using a twisted pair cable.
I/O control capacity of up to 4096 points
The master unit can accommodate up to 32 slave stations, or 4096 I/O points. FP3 master unit has two
ports which can handle 4 communication paths, and FP2 multi-wire link unit has one port which can
handle 2 communication paths. I/O decentralized/centralized control system can be easily established.
Note: Maximum number of points varies according to the combination of CPU unit and
master unit.
Reference: For the information on the types and combinations of units,
<Chapter 3 Unit Specifications>
A wide variety of I/O units and boards can be used
On the slave station, you can install I/O units for the FP3 by using the slave stations. You can also used
FP I/O terminal boards and FP I/O terminal units to increase the number of I/O points as necessary for
each slave station. When you use an I/O link unit, you can exchange I/O information with an FP0, FP1 or
FP-M.
* When using manifold solenoid valves for MEWNET-F made by various manufacturers, the direct
control of valves is achievable.
Effectively deals with errors such as a disconnection of the communication cable
In "Slave station connection confirmation mode", it waits fro xecuting the I/O control until all the
registered slave stations are connected. This operation prevents malfunctions to be occurred by the
delay in turning on the power supply of slave stations or cable disconnection. It is also possible to select
"Output status maintain function" that is used to hold the output of slave stations even if the tranmission
cable was disconnected in operation.
1-2
1.2 System Configuration
The remote I/O system [MEWNET-F] is a network which can be configured with master stations (CPU
unit + master unit) and slave stations (slave unit + I/O unit or various remote I/O exclusive I/O terminal)
with transmission cables (two-wire cable). The CPU unit of master station controls the I/O (remote I/O)
slave stations via the master unit.
*You can connect various kinds of slave stations on a single communication path from a master unit.
For example, the FP2 master unit can be connected to an FP3 slave unit and I/O terminal unit.

1.2.2 Slave Stations (Slave Unit, I/O Terminal, I/O Terminal Board, etc)
The I/O that is controlled by the master station (CPU unit and master unit) on the remote I/O system
[MEWNET-F] is called slave stations. A maximum of 32 stations can be connected per master unit, and
up to 4096 points of I/O can be controlled.
- Slave stations can be mixed. The FP3 system or exlusive I/O terminals are also controlled as slave
stations. There is not restriction on the order of connection and the composition ratio.
- Staton numbers are set to each slave station. I/O numbers are allocated in the order of station
numbers. It is not neccesary to set station numbers according to the order from the unit closer to the
master unit. Also, it is no problem there are blanks.
Overview of slave stations
-FP2/FP3 system (Slave station system)
This is the system with a slave unit installed in the CPU slot of the master backplane instead of a CPU
unit as "Slave station control part" shown above. (Note1, Note3) An advanced unit (Note2) can be used
as "I/O part" as well as I/O unit.
"Shared memory access function" is also available.
Note1) I/O can be added by connecting expansion backplane as well as the standard system. Up to 3
backplanes including a master backplane can be added.
Each length of expansion cables should not be longer than 1.2 m each for FP3, and 2.6 m
totally for FP2.
Note2) There are some advanced units which cannot be used for the slave station system.
Reference: <1.2.3 Advanced Units Not to be Used for Slave Station System of “MEWNET-F”>
Note3) The system cannot be controlled only by the slave unit without a master station.
-FP I/O Terminal Unit
As the [MEWNET-F] FP terminals, there are an I/O terminal board that the input and output are
combined and an I/O terminal unit (Note) that the input and output are separate. The "Slave station
control part" and "I/O part" shown in the above figure is contained in a single unit.
Note) There are an input unit and output unit for the I/O terminal unit. Also, number of controllable points
can be incrased or the input and output can be combined by connecting expansion units.
-FP0/FP1/FP-M & I/O Link Unit
The connection to the [MEWNET-F] network can be established by connecting the I/O link unit to
FP0/FP1/FP-M The I/O of FP0/FP1/FP-M cannot be directly controlled by the master station, however,
the I/O link area input of FP0/FP1/FP-M can be controlled with FP3 programs, or the remote I/O area
input of FP3 can be controlled with FP0/FP1/FP-M programs.
