Online help for myDataconC3+

General product information

ThemyDataconC3+ is a compact, stationary measurement system designed for installation in control cabinets. In its most comprehensive configuration, the system consists of a data logger, an input extension and an output extension. The extensions are optional, meaning that only one of them, or none at all, may be used. In addition to recording and transferring analogue or digital signals, it can be used for control and regulating tasks. The measurement system requires a continuous power supply. However, the data logger has an integrated rechargeable buffer battery which allows sending a notification in the event of a voltage supply failure. In addition to the 3 universal inputs on the data logger, further 12 universal inputs are available on the input extension. These inputs can be operated in various analogue or digital modes and allow for the myDataconC3+ to be compatible with a large number of different sensors. For controlling actuators the data logger has 2 relays, the input extension also has 2 relays and the output extension has 6 relays and additionally 3 active, galvanically separated analogue outpus available. The setpoints for the relays and the analogue output extensions can be determined wirelessly from a central point. The measurement data of the inputs are determined in an adjustable interval and together with the states of the outputs they are temporarily stored in an internal data memory. This stored data is sent to a central server for further processing in a freely selectable interval using the mobile network. The measurement system is equipped with an integrated SIM chip for establishing a mobile connection. By using the mobile network to transfer data to the server, the site rarely has to be physically accessed and the data can be accessed at all times.

Product characteristics:

  • Universal inputs for digital and analogue signals
  • Relay and mA outputs
  • Integrated rechargeable buffer battery to issue a message in the event of a power supply failure
  • Measurement value storage on the device
  • Data transmission to the server via mobile network
  • Location-independant management of the measurement sites via internet
  • Adjustable record and transmission interval
  • Device time synchronised with the sever
  • Hardware real-time clock
  • Very low commissioning & operating costs
  • Integrated durable SIM chip

Application:

  • Data collection
  • Transmission of measurement values of probes
  • Asset monitoring
  • Alarm monitoring

Frequently asked questions (FAQs)

Blink code Colour Description
1x green Last connection OK
2x red Last transmission faulty
7x red Network block/no matching provider
8x red No mobile network
10x red No mobile network connection
11x red No server available
12x red Faulty SIM chip

A detailed explanation is provided in section Status LED.

When the power supply is connected, the device automatically establishes a connection. The status LED initially flashes green to indicate that a connection is being established. Once the connection has been established, the status LED remains lit green.

If the connection has been interrupted, you can initiate the connection manually by holding down the "MDN" button for at least 3 seconds. You can recognise that there is currently no connection by the fact that the status LED is either off or displaying one of the error/status codes (see Status LED).

Regardless of the connection type selected (online or interval), the myDataconC3+ will automatically attempt to re-establish the connection if it is lost (see Procedure in case of connection aborts).

1 MDN Button    

The status LED is used both to display the error/status codes and to indicate the current operating state. The error/status codes are issued every 3 seconds unless there is an active mobile network connection.I.e. the output of error and status codes does not need to be enabled separately.

A detailed description is provided in section Status LED.

A detailed explanation is provided in section Connection of the sensors, actuators and the supply.

The extension modules are connected to the myDatalogC3xx using the CAN interface. All of the "FD L" terminals and all of the "FD H" terminals must be connected with one another during this process. The total length of the CAN bus must not exceed 20 m . No other bus participants such as sensors or actuators may be connected to the CAN bus. The 120 Ω load resistances (S3 and S4 of the dip switch) must be activated on the first and last bus participant.

Note: Use a shielded cable to connect the CAN interfaces. The "Shield" terminal is available on the extension modules to connect the cable shield. The cable shield on the myDatalogC3xx must be connected to the GND terminal. Use a twin wire end sleeve or distributor terminal if you want to connect several cables to the GND terminal.

Note: As there is only one terminal for each signal on themyDatalogC3xx and on the extension modules, you should use twin wire end sleeves if you want to use more than one extension module.

A detailed explanation is provided in section Connection of the extension modules.

If the Ready LED is green and the Error LED is off, the extension is working correctly.

1 Ready LED (input extension) 3 Ready LED (output extension)
2 Error LED (input extension) 4 Error LED (output extension)

 

Ready LED
LED Colour Description
on green extension module is ready for operation (voltage supply established and IO controller booted)
off --- No supply voltage or IO controller booting not yet finished

 

Error LED
LED Colour Description
on red Electrical connection faulty. No communication via CAN interface possible.
blinking red extension module has not yet been initialised through the myDatalogC3xx
off --- Communication between the extension module and the myDatalogC3xx via the CAN interface works correctly

 

Please refer to section Troubleshooting and repair for problem-solving.

The Dip switch to activate/deactivate the load resistances for the CAN interface is located on the rear of the devices. It is therefore recommended to set the load resistances before installing the devices.

A detailed explanation is provided in section Technical details about the CAN interface.

The myDataconC3+ does not have a special transport mode and therefore does not need to be deactivated.

A more detailed explanation is provided in section Storage of the product.

No.

The currently available variants of the myDataconC3+ are not equipped with a WiFi module. The port for the WiFi antenna is intended for future upgrades.

No.

The CAN interface is intended solely for connecting the extension modules.

No.

The RS485 interface is not supported by themyDataconC3+ . The RS485interface can only be used with the myDataconC3 MBM .

No.

In the currently available variants of the myDataconC3+ , the necessary hardware is no longer installed. The visible LAN socket could only be used with the "myDatalogC33x WIFI/2G/3G/4G World", which is, however, no longer available.
