Wiring
Wiring of power supply
The Power supply connection inside the unit has individual power
supplies for solenoid valve actuation (SV power supply) and for
Control parts and Sensor (SW power supply). Supply 24V DC for
each of them. Either single or dual power supply is available. Wiring
is not necessary for SW power supply when no Input Blocks are
used.

Voltage reduction of approx.1V
Power for a sensor is supplied to the sensor connected to an Input
Block. There will be a voltage drop of up to approx. 1V inside the SI
unit, therefore select a sensor which will operate with the resultant
voltage.
If a sensor requires 24V, it is necessary to lower power supply
voltage for sensor slightly or secure a power supply for sensor
separately without going through the SI unit so that sensor input
voltage can be 24V with actual loading (allowable voltage of sensor
power supply: 19.2V to 28.8V).

Baud Rate
The baud rate can be set in the HW mode using the following
methods: -
Method of re-setting to default baud rate (125kbps)
1) Turn off the power supply (for CANopen line) and set Node-
ID to 0 with DIP switches SW1-6.
2) The CAN LED will flash RED for five seconds at the
frequency of 2Hz when the power supply to the SI unit is
restored.
3) The baud rate is set to 125kbps and the CAN LED illuminates
green and red alternately (2Hz).
4) Turn off the power supply, set Node-ID, and turn on the
power supply again.
5) The CAN LED illuminates (GREEN). The SI units state of
communication is standby (When SI unit is stand by mode
Pre-operational).
Method of setting baud rate to value within CiA
specification
1) Turn OFF the power supply (for CANopen line) and set
Node-ID to 0 with DIP switches SW1-6.
2) The CAN LED will flash RED for five seconds at the
frequency of 2Hz when the power supply to the SI unit is
restored.
3) Set DIP switch SW6 to 1 while the CAN LED is flashing
(within five seconds).
4) The Flashing CAN LED stops (CAN LED is off). Set the baud
rate with DIP switches SW1-4 within ten seconds according
to the following table.
Wiring (continued)
Baud Rate (continued)
<Example: If the baud rate of the SI unit is set to 500kbps.>
Because the baud rate is 500kbps, DIP switches SW1-4 setting is 2.
i.e. SW1 = 0 , SW2 = 1 , SW3 = 0 and SW4 = 0
5) The CAN LED flashes RED for two seconds at the frequency
of 1Hz when the setting is successful.
6) After that, the CAN LED flashes RED for five seconds at a
frequency of 5Hz to acknowledge the end of the setting
procedure.
7) The CAN LED illuminates GREEN and RED alternately (at
the frequency of 2Hz).
8) Turn OFF the power supply, set the Node-ID, then turn ON
the power supply again.
9) The CAN LED will illuminate GREEN. The SI units state
ofcommunication is standby (Pre-operational mode).
It is the responsibility of the machine builder to make sure that the
machine operates correctly.
CANopen units from different manufacturers have different ability
(minimum message interval) respectively.
The machine builder should consider the differences in the ability.
The method (confirmed service) of sending the following request after
receiving the response to the request is recommended to ensure correct
communication.
When using the method (unconfirmed service) of sending the following
request without receiving a response to the request, if the request
exceeding the processing performance of the unit is sent, it cannot be
received.
Please confirm the normal operation beforehand when an SMC CANopen
unit is used in your machine.
Please consult with SMC when there is a problem.
