Product Summary

System configuration general

The reduced wiring system is connected to various kinds of fieldbus realizes the
reduced wiring and decentralized installation of I/O devices. The signals to/from
fieldbus are exchanged by GW unit, and the signals to/from decentralized I/O devices
are collected and delivered by GW unit.
The maximum number of connections of manifold valve/Input unit manifold is
16/branch x 4 branches = 64 points each for output and input.

As the cables with connectors are used for all wirings among devices, the system
complies with the IP65 environment.

Display/Switch Setting (continued )

*1 : Remote control (SW1 all dip-switches off)

SMC's EX500 GW Unit will respond to the following Rockwell Automation
BOOTP/DHCP Server commands.

Enable DHCP

Selecting this function will enable the EX500 GW Unit to retrieve its boot information
from the BOOTP/DHCP Server. If DHCP is enabled the EX500 GW Unit will retrieve its
boot information during the next power up.

Disable BOOTP/DHCP

Selecting this function will disable the EX500 to retrieve its boot information from the
BOOTP/DHCP Server, and causes the EX500 to retain its current configuration during
the next power up.

*2 : DHCP Mode (SW1 all dip-switches on)

The IP address is acquired via DHCP Server. The IP address is not saved and lost if the
power to the EX500 unit is cycled.

Mounting/Wiring

The mounting and removing methods of SI unit are as shown below.

For branch wiring method, refer to subsection "Wiring" ( page 15 ) of section "EX500"
in this manual. As the power to output devices such as solenoid valve is supplied by
branch wiring ( branch cable with M12 connector ), there is no need to supply power
individually.

Note 1

For mounting/installation methods of solenoid valve, manifold, etc., refer to the
catalogs, instruction manuals, technical data, etc. of each valve series.
When connecting general purpose output block only, refer to subsection "Mounting"
( page 34 ) of section "EX9 Series General Purpose Output Block" in this manual.

This wiring enables direct input of signals from
two points combined into one cable through

When connecting sensors, confirm the
specification of output signal carefully.
Otherwise malfunction can result.
The key position for mounting sensor
connector is as shown to the right. Consider
this key position when selecting sensor.

NOTE

Mount a waterproof cap on each unused connector of Input unit. The proper use of
waterproof cap can achieve IP65 Enclosure. The waterproof caps are delivered

EX9 Series General Purpose Output Block Part Names

The EX9 series general purpose output block is the unit to operate solenoid valve, relay,
etc. in combination with VQC and SV ( tie-rod ) series valve and applicable SI unit.
There are two types ---- one type is for low wattage load ( EX9-OET1 or EX9-OET2 ) that
outputs signals by receiving power supply from SI unit, and the other type is for high
wattage load ( EX9-OEP1 or EX9-OEP2 ) that outputs signals by receiving power supply
from outside. The type for high wattage load is used in combination with the power block
( EX9-PE1 ) connected with external power supply. As the low-wattage-load type is
powered from SI unit, the wattage of load is limited to 1.0W

( Note ). For a load up to

12W, use the power block and the high-wattage-load type.

Note : When connected with EX500 series.
