Instruction Manual
Gateway unit – PROFIBUS DP compatible
Series EX500-GPR1A
The intended use of the Gateway unit is for connection to SI units and
input devices for the control of pneumatic valves.
1 Safety Instructions
These safety instructions are intended to prevent hazardous situations
and/or equipment damage. These instructions indicate the level of
potential hazard with the labels of “Caution,” “Warning” or “Danger.”
They are all important notes for safety and must be followed in addition
to International Standards (ISO/IEC)*1), and other safety regulations.
*1) ISO 4414: Pneumatic fluid power - General rules relating to systems.
ISO 4413: Hydraulic fluid power - General rules relating to systems.
IEC 60204-1: Safety of machinery - Electrical equipment of machines.
(Part 1: General requirements)
ISO 10218-1: Manipulating industrial robots -Safety. etc.
•Refer to product catalogue, Operation Manual and Handling
Precautions for SMC Products for additional information.
•Keep this manual in a safe place for future reference.
Caution indicates a hazard with a low level of risk which, if
not avoided, could result in minor or moderate injury.
Warning indicates a hazard with a medium level of risk
which, if not avoided, could result in death or serious injury.
Danger indicates a hazard with a high level of risk which, if
not avoided, will result in death or serious injury.
Warning
•Always ensure compliance with relevant safety laws and
standards.
•All work must be carried out in a safe manner by a qualified person in
compliance with applicable national regulations.

3 Name and function of parts
Connection to PROFIBUS DP
Connection for power supply.
Connection to SI units (manifold valve)
or input units using a branch cable.

switches under the cover.
4 Installation
4.1 Direct mounting
Secure in position using 4 x M5 screws, 15 mm minimum thread length.
4.2 Wiring connections
•Communication Connector
Select the appropriate cables to mate with the connectors on the SI
unit. The PROFIBUS DP connection has 2 ports, BUS IN and BUS
OUT, and both ports can be used for connection.
M12 5-pin Plug / Socket (B-coded)
Pin No. Signal name
•Power Supply Connector
Connect the power supply to the power supply connector on the
Gateway unit. With this cable, power is supplied to the output devices
(such as solenoid valve) and the input devices and for control.
The M12 connector cable for fieldbus and power supply connections
has two types, Standard M12 and SPEEDCON compatible. If both
plug and socket have SPEEDCON connectors, the cable can be
inserted and connected by turning it a 1/2 rotation.
A standard connector can be connected to a SPEEDCON connector.
•Both single and two power supply systems can be adopted, however
the wiring should be made separately (for solenoid valves / outputs
and for input and control) for either system.
•Branch Connector
Connect SI units (solenoid valves) and input devices to the
communication connectors (COM A - D) using an M12 (8-pin)
connector cable (EX500-AC###-S#P#).
As each cable contains power supply wiring, there is no need to
supply power to the SI unit (solenoid valves) or input devices
separately.
Warning
•Be sure to fit a seal cap (EX9-AWTS) on any unused connectors.
Proper use of the seal cap enables the enclosure to maintain IP65
specification. Tightening torque: 0.1 N•m.
4.3 Ground Connection
•Connect the FE terminal (M3) to ground.
•Individual grounding should be provided close to the product with a
short cable to assure the safety and noise resistance of the system.
•Resistance to ground should be 100 Ω or less.
4 Installation (continued)
4.4 Environment Warning
•Do not use in an environment where corrosive gases, chemicals, salt
water or steam are present.
•Do not install in a location subject to vibration or impact in excess of
the product’s specifications.
•Do not mount in a location exposed to radiant heat that would result
in temperatures in excess of the product’s specifications.
5 Setting
5.1 Switch setting
•The switches should only be set with the power supply turned OFF.
•Open the switch protection cover and set the switches with a small
flat blade screwdriver.
•Be sure to set the switches before use.
•After setting the switches close the protective cover and tighten the
screws with the specified tightening torque of 0.6 N•m.
•The node address can be set in the range 0 – 125.
•The number of available nodes is up to 32 stations per branch, or 126
stations with a repeater.
•Bus terminator switch (SW4)
A bus terminator is required at both ends of the PROFIBUS DP bus
segment.
Switch SW4 ON if the Gateway unit is at the end of the bus segment.
5.2 Configuration
An applicable GSD file is required to configure the Gateway unit for the
PROFIBUS DP network. Download the latest GSD file from the SMC
website (URL: https://www.smcworld.com).
Technical documentation giving detailed configuration information can
be found on the SMC website (URL: https://www.smcworld.com).
