1.1 How the Multi-wire Link Unit Works

1.1.1 MEWNET-W Mode

A system can be configured economically between programmable controllers,
using twisted pair cables.

Link communication can be carried out between various programmable controllers, us­ing link relays and link registers.

Communication is possible with conventional FP series devices capable of using the
MEWNET-W.

Thelinkrelaysand link registersusedforPCLinkcommunicationarespecifiedusingthe

1.2 Specifications

(*1):Because polyvinyl chloride has poorer electrical character-

istics than polyethylene, the overall transmission distance
is shorter.

(*2):If products with the order numbers listed below are in-

cluded in the network when the F mode is used, the maxi­mum transmission distance is the distance noted in paren­theses. Information on the various types of commercially
available manifold solenoid valves should be confirmed
with the manufacturing company.
