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).gle or dual power supply is available.

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).

: 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)
: Mixed (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.

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
