About this Manual 3.

MPC

3.1.

The MPC is SMC's low cost Ethernet positioning cylinder. The MPC series offers a cylinder, solenoid
valve, linear positioner, and controller in one package. With its integral position control, the MPC
needs only power and Ethernet input signal. The target position is kept by opening and closing
solenoid valves controlling pressure on the cylinder. The MPC has an output signal to give position
feedback to a customer's controller. Standard ball bushings protect against side load.

Purpose 3.2.

The purpose of this manual is to provide the user with necessary information to install, configure,
and use the MPCXX-XXX-XXX-XX-DUT01607. The MPC may be operated under the control of a
network connected PLC. This manual provides information for MPC setup and configuration,
examples of the web interface, and a brief overview of the PLC. This document is not an operator’s
manual for the Rockwell PLC or any other PLC. Please see the PLC manufacturer’s documentation
for detailed instructions on the setup and use of your PLC.

Product Summary 5.

The MPCXX-XXX-XXX-XX-DUT01607 (MPC) is a multi-position cylinder which is controlled by an
Ethernet interface. MPCs move to a position value specified by the user. In the past, an electric
actuator was the only option for applications demanding a multiple number of stroke positions.
SMC's MPC series now provides an alternative and economical solution.
The Ethernet interface allows a user to configure, control, and monitor the MPC over a
communication link using commands sent from a PLC or internal webserver. The user can change
the position setpoint as required. The user can also monitor the operation of the MPC, verifying the
actual position.
Offered as a pneumatic and lower cost alternative, the MPC (Multi Position Cylinder) uses an
Ethernet input signal to automatically adjust the actuator stroke. Once the MPC reaches the desired
position, it is pneumatically locked until the input signal is changed.
To accomplish this, the MPC utilizes an integrated cylinder, solenoid valve, linear sensor, and
controller all in one unit. You need only to supply air, power, and the appropriate input signal. This
easy adjustment makes the MPC perfect for on the fly changes to your process.

Daisy Chaining Power and Ethernet 11.

The daisy chaining feature is an optional way to power MPC units. This eliminates the need to run a
power cable to each MPC from the power supply directly or running a separate power trunk line.
Daisy chaining can eliminates the need for long power cables.

Connecting MPCs for Daisy Chaining 11.1.

The cable connections are critical for proper operation of daisy chaining. The following is an
example of proper cable connections.
When daisy chaining, the first MPC can supply power to the next 19 MPCs without the need for
another power supply if using 48 volts. This drops to only 4 if using 24 volts. The MPC has under
voltage detection to let you know if you do not have enough voltage supplied to the MPC for proper
operation. The MPC does not limit the number of MPCs which can be connected to an Ethernet
network. The network size limits come from the PLC and how many devices it can talk to at one
time.

Figure 11-1 - MPC Group Power Connections

The diagram illustrates the Ethernet communication and power cable connections required to
support 21 MPCs when daisy chaining is in use. The MPCs in the dashed box form a single Power
daisy chain group. Note that power daisy chaining supports a maximum of 20 MPCs in one power
group. This does not mean that you cannot have more than 20 MPCs connected to a single supply.
More MPCs can be supported as long as the supply can source enough power to support multiple
chains of MPCs. Each MPC uses about 7 watts of power when moving.

The following rules must be followed for proper operation

Good quality power and Ethernet cables must be used when daisy chaining 11.1.1.
No more than 4 amps per connector pair should be placed across MPC power In to 11.1.2.

Power Out. This is a total of 8 amps if using both connector pairs as is suggested
when using daisy chaining to reduce line and connector voltage loss.

Setpoint 14.

Users specifying the Setpoint (position) using a PLC need to be aware that the PLC and Ethernet
MPC use counts (see Terminology) to represent the position setpoint (from the PLC) and the
current position value (from the MPC). These values are displayed as 16-bit hexadecimal
quantities. (The 4 MSB should always be 0).
If the PLC allows a user to enter the position in units, for example, millimeters, it is the
responsibility of the PLC program to convert the position in millimeters to the appropriate count
value. It is also the responsibility of the PLC program to convert the position return value (current
position) from counts to millimeters as needed for use on the PLC.
The following formula is used to calculate the position in counts given the position in a
measurement unit and the scale factor: Position Value = Counts/Scale Factor or Counts =

Position Value * Scale Factor.

If a value larger than 4095 (0X0FFF) is sent from the PLC to the MPC, the MPC will go to the
maximum supported position (4095 counts).

IN20267

Table 14-1 - MPC Scale Factors

Example: Convert the Position to Counts 14.1.

Suppose you have specified a position of 50mm for a 100mm MPC. In order to convert that position
to counts, use the formula above as follows: Find the scale factor corresponding to the MPC body
type and the position measurement units in the table (above): In this case, the scale factor is 40.95.
As a result, counts = 50 * 40.95 = 2047.5. Since the pressure value in counts passed between the
PLC and the MPC must be an integer, round to 2048 or 0x800.

Example. : Pseudo Code for 100mm MPC mm 14.2.

// MPC slider and Feedback calculations
MPC_Setpoint = Slider_Setpoint * 40.95
Display_Feedback = MPC_Feedback / 40.95

Ladder Logic Example 14.3.

PLC Example Code: This is a quick PLC code snippet showing how to scale the position to which
you wish to move. The MUL instruction is used to convert from millimeters to counts. The tag
Set_Position_mm is used hold the engineering unit you wish to move to. The 40.95 is the scale
factor needed to convert from millimeters to counts that the 100 mm Ethernet MPC will
understand. MPC_1:O.Data[0] is tag for the output to the Ethernet MPC. The scale factor just has to
change if using a different stroke length MPC or if you prefer the imperial system to metric.

Installation and Handling 17.

Air supply

17.1.

Use clean air.
Do not use compressed air that contains chemicals, synthetic oils including organic solvents, salts
or corrosive gases, etc., as this may cause damage or malfunction.

Air quality
Take measures to ensure air quality, such as installing an aftercooler, air dryer or water separator.
Compressed air containing large amounts of condensate may cause malfunction of pneumatic
equipment.

Lubrication
Do not lubricate the cylinders.
Lubrication of this cylinder may cause malfunction. Lubrication other than as specified may cause
operating failure. If grease is required for maintenance, order using the part number: GR-H-010 （
10g)

Do not wipe off the grease applied to the sliding part of the air cylinder.
If grease applied to the sliding part is forcibly removed, operation failure can result.
The sliding part may turn black if the cylinder is operated for a long distance. In such a case, wipe
off the grease on the sliding part and apply fresh grease for a long time operation. Use a cloth with
water to remove the grease. Alcohol or special solvent may cause damage to the seals.

Operating environment 17.2.

Do not use in an environment where corrosive gases, chemicals, or sea water are present. These
may cause failure or malfunction.

Do not use the product in an environment where the product may be splashed by oil or chemicals.
If the product is to be used in an environment containing oils or chemicals such as coolant or
cleaning solvent, even for a short time, it may be adversely affected (damage, malfunction, or
hardening of the lead wires).

Do not use the product in a food zone: 17.3.

Do not use the product in; Food zone: An environment in which foods directly get into contact with
the cylinder, and the food will be handled as a commodity.

OK to use the product in: 17.4.

Splash zone: An environment in which foods can directly contact the cylinder, but the food that has
contacted the cylinder will not be handled as a commodity.

Non-food zone - An environment in which foods do not contact the cylinder:

17.5.

In locations where the cylinder is exposed to water, dust etc., there is a possibility that these
contaminants can enter into the cylinder through the auxiliary ports. Connect tubing from the EXH
port and VENT port, and extend the tubing to a location where there is no contaminants.

Do not use in an area where surges are generated: 17.6.

If there are machines or equipment that generate large surges near the product (magnetic type
lifter, high frequency inductive furnace, motor, etc.), this can result in deterioration and damage to
internal components. Take protective measures to isolate the surge sources, and prevent the
lines from coming into close contact.

IN20267

- 42 -

IN20267
Do not use a load which generates surge voltage.
When a surge-generating load such as a relay or solenoid is directly driven, use the product with a
surge absorbing element built-in.

The product is not immune to lightning strikes. Take measures against lightning strikes in the
system. Failure or malfunction may result.

Do not use in an area where a magnetic field is generated. Malfunction may result.

Do not let foreign matter, such as wire debris, get inside the product. Failure or malfunction may
result.

Do not use the product in an environment that is exposed to cyclic temperature patterns. Heat
cycles other than ordinary changes in temperature can adversely affect the internal components of
the product.

Do not expose the product to direct sunlight. If using in a location directly exposed to sunlight,
protect the product from the sunlight. Failure or malfunction may result.

Keep within the specified operating temperature range. The operating temperature range is 0 to
50oC. Operation under low temperature may lead to damage or operation failure due to frozen
moisture in the fluid or air. Protection against freezing is necessary. Avoid abrupt temperature
changes even within the specified temperature range.

Do not operate close to a heat source, or in a location exposed to radiant heat.

Installation 17.7.

Do not synchronize cylinders coupled to the same load.
As air is a compressible fluid, it is affected by fluctuations in the supply pressure, load, temperature
and lubrication conditions, and deviation in the performance of individual cylinders, and the change
of components over time. Therefore, it is possible to synchronize multiple cylinders for a short
period of time, but the synchronization could fail due to changes in various conditions. When the
synchronization fails, an excessive force will be applied to the piston rod, causing failure or
malfunction. If the synchronized use is unavoidable, provide a guide with high rigidity and high
precision to prevent failure of synchronization from the difference in force of the cylinders.

Do not place your hands or fingers in the clearance between the plate and the cylinder tube.
Injury may result if fingers are trapped between the plate and cylinder tube when the piston rod is
retracted. Never place hands or fingers in this area. The cylinder is able to generate great force; it
can lead to injury if hands or fingers are trapped.

Do not scratch or dent the sliding surfaces of the piston rod and the sensor rod.
Damage to the seals may lead to air leakage or operation failure.

Avoid applying rotating torque to the plate. When tightening a screw into the thread on the plate,
the piston rod should be fully retracted. Tighten it by giving consideration to preventing tightening
torque from being applied to the sensor rod.

Do not operate the cylinder in an application in which the piston rod stops before the positioning
stop. (e.g. Stoppage by clamping or external stopper) This may lead to premature failure of the
product.

- 43 -

IN20267
Plate load should be mounted so that the center of the gravity of the load will be on the piston rod
shaft. Failure or malfunction may result.
Do not touch the sensor rod.

Do not drop, hit or apply shock to the product. Damage to the internal components may result,
causing malfunction.

Do not pull the lead wire forcefully, or lift the product by the lead wire. Hold the product body
when handling to prevent damage, failure or malfunction. The product will be damaged, leading to
failure and malfunction.

Never mount a product in a location that will be used as a foothold. The product may be damaged if
excessive force is applied by stepping or climbing onto it.

Do not use this cylinder as a stopper.

Minimum adjusting stroke necessary for a positioning stop is 5mm. Operate for 5mm or more
before a positioning stop.

Ex: 1. To operate from the stop position 20mm to 22mm; 20mm → 15mm → 22mm
Ex: 2. To operate to the stop position of 3mm; 0mm → 8mm → 3mm

Wiring (Including connecting/disconnecting of the connectors) 17.8.

Wire the cable to the connector of the body as shown below. Incorrect wiring can result in damage
to the product.

Make sure the product is grounded to ensure noise tolerance. Otherwise malfunction can result.

Do not pull hard on the lead wire.
Never lift the product equipped with tubing by holding the lead wires. Damage to the connector,
circuit board, cover or internal components may result, causing failure or malfunction.

Avoid repeatedly bending, stretching or applying a heavy object or force to the lead wire.
Repetitive bending stress or tensile stress can cause the sheath of the wire to peel off, or break the
wire. If the lead wire can move, fix it near the product. The recommended bend radius of the lead
wire is 6 times the outside diameter of the sheath, or 33 times the outside diameter of the
insulation material, whichever is larger. Replace a damaged lead wire with a new one.

Wire correctly. Incorrect wiring may cause malfunction or damage to the product. Do not perform
wiring while the power is on. Damage to the internal components may result, causing malfunction.

Do not route wires and cables together with power or high voltage cables. Route the wires of the
product separately from power or high voltage cables to prevent noise and surge from entering the
product.

Verify the insulation of wiring.
Poor insulation (interference with other circuits, poor insulation between terminals etc.) can apply
excessive voltage or current to the product causing damage.

Keep wiring as short as possible to prevent interference from electromagnetic noise and surge
voltage. Do not use a cable longer than 100m.
Wire the DC (-) line as close as possible to the power supply.

Adjustment and Operation 17.9.

When the product is supplied with pressure for the first time or when the operating pressure is
changed after the product is mounted to the application, operate the product for 1 or more
reciprocating operations before starting the operation. Failure to follow this procedure may cause
the product to malfunction.

There is a possibility of rod extrusion or overshooting when starting retraction depending on the
operating conditions such as vertical operation, plate load or operating pressure. Assure proper
operation before using the product.

Do not short circuit the load.
When the product load has a short circuit, over current may be generated, leading to damage of the
product.

- 46 -

Washing 18.

When washing the product with steam, stay within the cylinder temperature range and wash
quickly. If the sliding part is washed, the grease may be washed away, reducing the product life.
Washing should be as infrequent as possible.

When washing the product using a brush, avoid applying excess force to the parts such as the lead
wire and plastic cover, as these components are easily damaged.

IN20267

IN20267

Maintenance 19.

Do not disassemble or retrofit the product. Failure or malfunction may result.

Perform periodical checks.
There is a risk of unexpected failure of components due to the malfunction of equipment and
machinery.

Turn off the power supply, shut off the air supply, exhaust residual compressed air in the piping and
verify the release of air before performing maintenance. There is a risk of unexpected operation.

Do not use solvents such as benzene, thinner etc. to clean the product. This may damage the surface
of the body and erase the markings on the body. Use a soft cloth to remove stains. For heavy stains,
use a cloth soaked with diluted neutral detergent and fully squeezed, then wipe up the stains again
with a dry cloth.

Recovering the IP Address of SMC Ethernet MPC 20.

The Ethernet MPC has a factory preconfigured static IP address of (192.168.1.20). Use this
procedure when the current IP address of an Ethernet MPC is unknown. The IP address can be
modified using the eight switches located under the cover of the Ethernet MPC. Power should be off
to the unit or the power cable should be unplugged. In order to access the switches remove the 5
screws that hold the cover on using a 2.5mm Allen key. Carefully lift the cover off reveling the dip
switches at one end of the circuit board stack.

The switches represent the lower octet of the IP address, the value of X in this example:

192.168.1.X. A switch is a binary 1 when it is pushed up toward the upper circuit board or a binary
0 when pushed down. The switch which corresponds to the most-significant-bit (MSB) of the lower
octet is located on the right. The switches are read by the Ethernet MPC upon application of power.
When power is applied, the state of the switches will then be used to determine the lower octet of
the IP address.

The switches come from the factory set to a collective decimal value of 255 (all switches pushed up).
The IP address stored in flash (i.e. set from the webpage) is used when the switches are set to 255.
When the switches are set to 0 (all switches pushed down) the factory defaults of the device are
restored on power application.

The user can then modify the IP address to the desired value via the webpage. REMINDER: to use
the address set from the webpage the switches need to be returned to 255 or, if left at 0, the factory
defaults will return on the next power cycle. A switch value different from 0 or 255 will cause the
lower octet of the IP address to assume the corresponding value of the switches. Additional
information related to network setup can be found in the sections Web Page Access and Network
Page.
