Data Logging

Included for free with your user account is the ability to create four data logs per module that log digital and analog input at 10 to 60 minute intervals. You can set the frequency at which the data is log, view historical graphs, and download the log file.

Types of Logs and Requires Settings

Analog Input Logging

Log an analog input at a specific interval.

I/O channel settings
Channel Push Update Mode: Push Analog Input Value Periodically
Auto Message Period: greater than zero and less than or equal to the data log frequency

Analog Input Averaging

Average the analog inputs collected over a period of time. This is similar to Analog Input Logging except multiple data points received within a specific period will be averaged together and recorded as a single data point.

I/O channel settings
Channel Push Update Mode: Push Analog Input Value Periodically
Auto Message Period: greater than zero and less than or equal to the data log frequency

Digital Input Logging

Log a digital input at a specific interval.

I/O channel settings
Channel Push Update Mode: Push Digital Input State Periodically
Auto Message Period: greater than zero and less than or equal to the data log frequency

Digital Input Counting

Count the number of digital state transitions.

I/O channel settings
Channel Push Update Mode: Push Update on Digital State Change

Pulse Count Logging

Log the pulse count from a module channel via the digital input pin.

I/O channel settings
Pulse Count Type: Negative Edge Counting

Pulse Count Type: Positive Edge Counting

Pulse Count Type: Both Negative and Positive Edge Counting

Onboard Action
Add Rule »

Push Update Rule »

Pulse Count (Push at Interval and Reset Count) »

Select Channel »

Enter a push interval in seconds

Setup

To create a log, select the Modules tab and click “Add Log”. You get to choose the log type, module, channel, frequency, analog scale, and digital state options.

Viewing Data Log

Once your log starts to fill up with data you can view a chart and the ability to download the log from any given time period.

Arduino

Almost any microcontroller is compatible with the ioBridge IO-204 via its native Serial Out our full-duplex Serial Smart Board. Currently, the Arduino is by far the most popular starter MCU platform.

EasyDAQ

System Overview

EasyDAQ has created a low cost, general purpose, secure, web/internet based DAQ & automation/control module options by integrating EasyDAQ serial relay control modules with the ioBridge IO-204. The system is ideally suited to a wide range of industrial, scientific, academic and research projects as well as home automation & hobbyist applications. Once setup, you can access or control from any web/browser enabled device including phones & PDA's such as iPhone and Blackberry. Programmatic access/control is provided via HTML, LabVIEW, Java, Perl, Python, Ruby, PHP and Ajax access/programming options - compatible with all internet/web browsers running on Windows 2000/XP/Vista, Windows 7, Windows CE, MacOSX and Linux platforms.

SER8PRMx

This general purpose, Serial/RS232 card has 8 opto isolated relays. Relays & PCB tracking are designed to handle 240VAC@10A. Suitable for a wide range of control and mains voltage power switching, or signal switching purposes, it offers screw terminal access to the NO, COM & NC relay contacts and 0V/+5V power connections for possible onward powering/use in your target system.

Relay control/activation is via simple ASCII/Hex characters. The card connects to an open channel on the ioBridge IO-204 via a 'straight through' cable (9 way D Type connector). All relay contacts are connected to screw terminal blocks along each side of the card. 5VDC power connection is made via a 2.1mm jack socket or screw terminal block. Wiring from the screw terminal block power connections can also be routed to the relay contacts and onward switching/control of your target hardware. The card is stackable, via corner fixing holes.

The card comes with +5V & relay channel LED status indicators. This card requires an external +5V PSU (requires approx 60mA per relay activated).

EasyDAQ SER8PRMx

SER16PRMx

This general purpose, Serial/RS232 card has 8 relays + 8 general purpose DIO channels + 8 channels that can be selected as either relay or DIO channels (via onboard links). Relays & PCB tracking are designed to handle 240VAC@10A. Suitable for a wide range of control and mains voltage power switching, or signal switching purposes, it also offers screw terminal access to the USB power connections for possible onward powering/use in your target system.

Relay & DIO control/activation is via simple ASCII/Hex characters. The card connects to an open channel on the via a 'straight through' cable (9 way D Type connector). All relay contacts are connected to two-part screw terminal blocks along each side of the card. These allow rapid connect/ disconnect or swap-over in your target system. 5VDC power connection is made via a 2 way screw terminal block or 2.1mm jack socket. The card is stackable, via corner fixing holes.

DIO channels are normal logic level signals (+5V max) and can supply up to 20mA per channel. Access to all relay contacts and DIO channels is via 2 part (male/female) screw terminal block connectors positioned along two edges of the card.

The card comes with +5V & relay/DIO channel LED status indicators. This card requires an external +5V PSU (requires approx 60mA per relay activated).

Control

Protocol

ASCII characters are used to send commands to the EasyDAQ Serial Relay Controllers via the IO-204Mx.

Process

Set ports to outputs (only needs to be set once)
Set state of relays
Repeat Step 2

Command to Set Port to Outputs

For Relays 1-8, send “B%00”
For Relays 9-16, send “E%00”

Command to Set State of Relays

For Relays 1-8, send “C%” + hexadecimal state
For Relays 9-16, send “F%” + hexadecimal state

You can set the state of 8 relays by sending one command plus a 2-digit hexidecimal value representating the binary state of each relay.

Each of the 8 relays have an “On” and “Off” state indicated by a binary 1 or 0. Relay 1 is the least significant digit and Relay 8 is the most significant digit.

Use this online Binary to Hex Calculator to easily convert the relay states to hexadecimal.

Here are some examples to help:

“00000000” indicates that the state of all 8 relays are off. The binary string of “00000000” is “00” in hexadecimal.

All relays turned on would be indicated by the binary string of “11111111” or in hex “FF”.

To turn on the first relay, the binary strong would be “00000001” or “01” in hex.

To turn on the second, third, and eight relay, the binary string would be “10000110” or “86” in hex.

Web Widget

The web widget allows for programmatic access to anything (LabVIEW, Java, Perl, PHP, C++, etc.) that can send an HTTP POST or GET request. The widget is a conduit for control commands sent via HTTP by directly embedding the widget on a website or accessing the widget via the Static Widget API.
