EX500 Serial System

EX## - OME0008

1. Outline

A. Gateway ( GW ) Unit

( 1 ) The Gateway ( GW ) Unit can be connected with a PLC.

At present, Gateway ( GW ) Unit with the following communication protocols are available:

Remote I/O ( RIO ) System slaves to Rockwell Automation PLC and SLC series unit.

DeviceNet

PROFIBUS-DP

( 2 ) The Gateway ( GW ) Unit can be connected with Manifold Valve / Relay Output Module with the SI Unit, and Input Unit / Input Block can be controlled in a decentralized fashion.

It is not necessary to supply power to I/O unit individually because power supply line is built in the communication port.

( 3 ) Transmission delay time problem will not occur because the communication with each branch is running by separate asynchronized transmission form from upper transmission form.

( 4 ) 16 input points per input manifold and 16 output points per output manifold can be controlled in a decentralized fashion per one branch ( 1CH ) of GW Unit. GW Unit communication ports and in / output can control 128 decentralized I/O points.

CAUTION

Maximum number of I/O points depends on the communication protocol and the host PLC.

B. Input / Output Unit

( 1 ) Input Unit Manifold ( Input Unit / Input Block )

The Input Block can be increased or decreased by two points. A maximum of 8 blocks can be used on a single input manifold.

( 2 ) Output Manifold Valve / Relay Output Module with the SI Unit ( SV series , VQC series )

The SV series and the VQC series Manifold Valve can be used with the EX500 series SI Unit.

The number of Solenoid Valve and Relay Output Module can be increased / decreased by the block alone. A maximum of 8 Double Solenoid Valve and / or 2 point Relay Output Module can be connected.

And a maximum of 16 Single Solenoid Valve and / or 1 point Relay Output Module can be connected with each channel.
