10Volt/mA Input Module
Cdios 6160

Command / Reply / Event messages V2.1
New or up-date devices are visible marked V2.x 

 


Cdios controller commands |Cdios download page | 6160 Cdios Module V2.0 Commands

Addition to V2.0:

  • When sampling less then 4 channels, the first channel to sample can be set
  • Sample timing error resolved

All CDIOS messages are presented as 8 bytes long. When variable length messages are selected, the part of the message that is not send over the CAN bus is represented in italic/lightgray text.

All multibyte (16 bits) parameters or values are placed in the messages with the LSB first (little endian)


Command code 28h: Read analog inputs

This command reads one of the 4 inputs or latched inputs.

The START parameter defines the first channel to sample.

The allowed value of this parameter depends on the amount of channels selected with the Config parameter

  Measured channels

NOTE: when the basic sample rate (200/100/60/50 SPS) is changed the A/D converter is stopped and an internal auto-calibration is performed. This takes up to 1 second before the A/D converter resumes it normal operation and a new sample is ready.

When the amount of channels or the start channel is changed, it takes approx. 15 mS plus the total sample time of all selected channels before a new sample is ready.

Input events react directly on the actual inputs, not on latched inputs.

NOTE: when the basic sample rate (200/100/60/50 SPS) is changed the A/D converter is stopped and an internal auto-calibration is performed. This takes up to 1 second before the A/D converter resumes it normal operation and a new event is send.

When the amount of channels or the start channel is changed, it takes approx. 15 mS plus the total sample time of all selected channels before a new event is send.


Calibration

The 6160 is calibrated by CD Systems before delivery.

All calibration values are stored in the internal calibration FLASH EEPROM.

Calibration commands and protocol are described in 6160-calibration.
