1 Introduction
This document describes the commands of the serial RS-485 communication protocol between a
user application and the DynaPCN-10-10-01.
The communication is based on a Serial Network Protocol (SNP).
If no serials are available, you can install the RS-485 emulator via USB.
This protocol allows to receive and send messages via serial port by the routines SNP_Recv() and
SNP_Send().
To properly build a packet for this protocol, SNP_Send() uses BuildSNPCommand().
For more information refer to the document: DynaPCN-10-10-01 User Manual.
Each command is represented d in the following way:

Gets the status of the PCN and the diagnostic error code
Parameters
Parameters Description
Returns
1 unsigned char (1 byte) value.
The byte indicates the status of the system: see Table 3.
Table 3. Error Codes and their meaning
Error code
Meaning
0
No errors
1
Right sensor occluded
2
Left sensor occluded
3
Both sensors occluded
4
Right sensor obscured
8
Left sensor obscured
12
Both sensors obscured
16
High difference between right and left sensors
20,24,28
High difference between right and left sensors and both sensors obscured
The difference between occluded and obscured is the following:
• Occluded: This is a condition of complete masking of one or both sensors (example: a thick label attached on the sensor,
or sensor broken).
It should be better to verify if the PCN is ok
• Obscured: This is a lighter condition than the Occluded one. In this case the masking of one or both sensors is partial
and transitory. Generally this condition does not affect the counting.
