European Marketing Centre EX510EX510

• The electronic industry and in particular the users related to the semi-conductor industry were the original target for the EX510 system.

Background

• In addition the EX510 series was also developed to expand sales of SMC’s other serial interface systems, in particular series EX500.

• When EX510 was first released it was only compatible with network protocols that are popular in Japan, such as CC-Link & DeviceNet.• But to expand sales in overseas markets the network

compatibility has been increased to include PROFIBUS-DP, which is especially popular in Europe.


Features 1/3

• With a conventional wiring system, all inputs and outputs are connected directly to the PLC

Features 2/3

• All inputs and outputs are processed from the PLC through a gateway unit.

• This results in wire savings and improved efficiencies

Gateway Unit Features 1/5 • Compatible with the following network protocols

• Maximum of 128 points• 64 input points• 64 output points

• A total of 4 input branches and 4 output branches per gateway unit• A maximum of 16 points per branch

4 input branches

4 output branches

• Transmission delay between gateway and I/O units is 1 ms or less


• The number of utilised points used per gateway can be configured to realise flexible I/O:

• This allows unused points to be used elsewhere, saving memory and reducing bandwidth requirements

Total: 128 pointsInput side: 4 branches x 16 points

Output side: 4 branches x 16 points

Total: 32 pointsInput side: 2 branches x 8 points

Output side: 2 branches x 8 points

• Multiple combinations of input & output configurations can be realised depending on the protocol

Gateway Unit Features 2/5


• It is only necessary to set the address for the gateway unit and not the individual I/O units• Therefore to change protocols, only the gateway unit

needs changing, not all the slave units

• It is only necessary to connect the power supply to the gateway unit• This results in wire savings as there is no separate

power supply cable for the input & output units

• Branch connector cables combine communication and power supply

Communication lines

Power supply linesBranch cable (4-wire flat ribbon cable)



• No special tools required for installing cables• With the adoption of special connectors there is no

need to strip the wire• Only pliers are needed for clamping

• This results in time savings and labour savings for the installation

Branch connector e-con connector


• The power supply & communication connectors for the gateway unit are included as standard


• Cable lengths of up to 20 metres from the gateway unit are possible


• Gateway unit is suitable for mounting inside a cabinet• DIN rail mount• Compact design• IP20 enclosure protection


Input Unit Features 1/3 • Input units with a maximum of 16 input points

• Two models with different input types• 1 e-con connector = 2 inputs (8 connectors in total)• 1 e-con connector = 1 input (16 connectors in total)

• Compliant to either NPN, PNP or 2-wire sensor inputs


Input Unit Features 2/3 • Possible to connect a wide range of input devices

• All input connections are e-con type • No special tools required, just pliers for clamping

Input Unit Features 3/3 • Fuse protection against short circuiting

• Possible to mount either directly onto a DIN rail or on the bracket accessory

SI Unit Features 1/3 • SI units with a maximum of 16 output points• Two models with different output types

• NPN output• PNP output

• Three mounting types

Direct screw mount Vertical DIN rail mount

Horizontal DIN rail mount

• Available as a standalone unit for converting existing valve manifolds to serial interface, or…


SI Unit Features 2/3 • The SI unit is also available pre-assembled with

some of SMC’s most popular valve series:• Series SY3000/5000/7000/9000• Series SYJ3000/5000/7000• Series VQZ1000/2000/3000• More series coming soon including plug-in type

• This saves the user from assembling the SI unit, valves and wiring to the manifold


SI Unit Features 3/3 • Integrated short circuit protection

• Additional output cables are available so that unused points on the SI unit can be utilised effectively

Applications 2/3

• Nearly every application and automatic machine where the control structure has a certain degree of complexity is a good opportunity to use field buses.

• With the new EX510, SMC’s product range in terms of serial interfaces is now broader and can cover more possible applications with more optimised solutions. For instance, EX510 is:

• more suitable for applications that don’t require IP65 enclosure protection

• more suitable for mounting in a cabinet due to its compact dimensions

• an entry level field bus system that can also be cheaper due its lower enclosure protection


Applications 3/3• Additional EX510 units to be released soon…

• General output unit

• Plug-in type valve manifolds with SI unit
