This chapter describes the implementation of the SDCI (single-drop digital communication
interface) protocol, more commonly known as IO-Link, for the Camozzi proportional pressure
regulator.
Port type
Class A
Protocol version
V1.1
Device ID
1
Vendor ID
805
ISDU
Supported
Block parameter
Data Storage
SIO
Not supported
Local Parametrization
Bit rate
COM2 (38.4 kbps)
Minimum cycle time
2400 µs
Process data IN (PRE → Master)
2 byte
Process data OUT (Master → PRE)
2 byte
In according to the standard protocol, three different data exchange device-master type are
supported:
-
Process data: cyclic data exchange.
-
On-request data: on request data exchange, usually configuration parameter.
-
Events: events generated by the device, usually diagnostic parameters.
13.1.
Cyclic data
In case of the Regulator, there are two types of Process Data:
•
Target Pressure: input data with a size of 2 bytes is sent by the master and indicates the
output pressure of the regulator.
•
Read Pressure: output data with a size of 2 bytes is sent by the Regulator and indicates
the pressure read by its internal sensor.
The Pressure Regulator supports three units of measurement: psi/10, mbar and kPa.
The pressure target resolution based on the units is:
•
0,1 psi/bit
•
1 mbar/bit
•
1 kPa/bit
