Power supply wiring
Power supply line inside the unit has individual power supplies for solenoid valve
actuation (SV power supply) and for Control parts and Input block (SI•SW power
supply). Supply 24 VDC for each of them. Either single or dual power supply is
available.
•Communication connector
12 5pin (Plug)
Example of connected cable: S C EX500-AP0∗0-S etc.
Power for sensor is supplied to sensor connected with Input block. Select sensor concerning
voltage drop up to maximum 1 V inside the unit at this moment.
If sensor requires 24 V, it is necessary to lower power supply voltage for sensor slightly or
secure power supply for sensor separately without going through SI unit so that sensor input
voltage can be 24 V with actual loading
(allowable voltage of power supply: 19.2 V to 28.8
V)

Configuration
In PROFIBUS DP, a device database file called the Generic Station Description (GSD)
file provides configuration information specific to the device (ID number, data format,
baud rate...).
The GSD file of the product depends on the address setting mode (selected by the
address setting mode switch).
GSD file : S CA1409.gsd (In hardware setting mode)
S CA1408.gsd (In software setting mode)

∗: Input numbers are assigned to stations from SI unit side to input side in order.
∗: Each bit of data read into master 4bytes shows ON/OFF of sensor connected to input block.
Starting from LSB of first byte (Offset 0), input numbers are assigned to all bits in numeric order.
Diagnosis infor ation
Diagnosis information of the SI unit is composed of 6 bytes standard diagnosis
information and 7 bytes SI unit status information, 13 bytes in total, as specified in
PROFIBUS DP.
When the SI unit is in a non-standard state, it will send an error message to the master
as diagnosis information, and light up the DIA display.
Technical documentation giving detailed diagnosis information and set-up steps
information can be found on the S C website (URL http://www.smcworld.com).
It detects when the voltage of the solenoid valve lowers
to approximately 19 V or less.
Contents

side due to the broken fuse of the Input block.

Function
Input block open fuse surveillance
SI unit status information is as follows
Refer to PROFIBUS specifications and manual of the master, etc. for how to refer to
diagnosis information on the master.
∗: Output numbers are assigned to stations from side D to U of manifold in order. (See manual of
each valve manifold for the directions of side D and U)
∗: Standard manifold is wired in double. Output numbers are assigned to side A and B alternatively.
In case of single solenoid valve, output on side B is free. (Refer to fig.a)
∗: ixed (single and double) wiring is available as long as wiring specifications designate it.
This allows output numbers to be specified without having free output. (Refer to fig.b)
∗: Each bit of data sent from master (4 bytes) shows ON/OFF (0: OFF, 1: ON) of solenoid valve.
Starting from LSB of the first byte (Offset 0), output numbers are assigned to all the bits in
numeric order.
∗: When software setting mode is selected, address setting switches are not effectual. oreover,
software setting mode and hardware setting mode differ in ID numbers of units.
Note: Specifications are subject to change without prior notice and any obligation on the part of the manufacturer.
