Description

LT3669-2IO-Link Device with Multiple Sensors

Demonstration circuit 2227A is a complete IO-Link® de-vice built using the LT®3669-2 to implement an IO-Link v1.1 physical interface (PHY). The IO-Link stack protocol runs on an Atmel ATmega microcontroller which connects to LT3669-2’s logic IO-signals to communicate with an IO-Link master via the CQ1 transceiver.

An LTC2997 temperature sensor, an opto-coupler (light barrier) and a pushbutton demonstrate IO-Link device functionality and master-slave interoperability.

DEMO MANUAL DC2227A

Quick start proceDureAdditional Hardware and Software Requirements

To operate the DC2227A demo circuit in IO-Link mode, additional hardware and software are required:

• PC running Windows XP or later with Ethernet Card. Alternatively a USB-to-Ethernet adaptor can also be used

• LTC IO-Link Master Demo Circuit DC2228A

• DC2228A Control Tool Software

• PoE Injector or 24V Power Supply

• DC2227A IODD Files (COM2 and COM3)

Set-up Preparation (See Figures 1 and 2)

1. Download and install the DC2228A Control Tool soft-ware from:

www.linear.com/demo/DC2228A

2. Connect the DC2228A to power and the host com-puter. Refer to the DC2228A demo manual for detailed information about the different configuration options to supply the DC2228A and interface it to the PC.

3. Using a 3-wire IO-Link cable of up to 20m in length with M12 connectors, plug the male terminal to one of the 8-ports of the DC2228A (for example port 2 like in Figure 1) and the female terminal to the DC2227A.

4. Run the DC2228A Control Tool on the PC and connect to the DC2228A. See the DC2228A demo manual for detailed information of how to select the DC2228A as the master, configure the IP parameters and establish communication between the host computer and the master.

Operation in IO-Link Mode (See Figures 1 and 2)

5. Download the DC2227A IODD files from:

www.linear.com/demo/DC2227A

6. Click on the “Select Device” button and import the IODD files by selecting the downloaded xml files and then clicking on the “Import” button (one at a time).

Operation in COM2

7. Click on the “Select Device” button again, this time making sure the correct port is selected. Use the fol-lowing IODD file:

TEConcept_GmbH-65538-<YYYYMMDD>-IODD1.1.xml

8. If the device is off, switch it on, enabling the L+ sup-ply of the connected master’s port by pressing the “Power ON” button keeping the light barrier open during power-up. If the device was already powered on coming from COM3 mode, power cycle it keeping the light barrier open to restart the device in COM2 mode. See the Light Barrier section for more information.

9. Start IO-Link communication by pressing the “IO-Link” button. The “Min. Cycle Time” is set to 20ms.

10. If a different IODD file is to be selected, stop IO-Link communication first by pressing the “Inactive” button to revert the DC2227A into SIO mode.

Operation in COM3

11. Click on the “Select Device” button again making sure the correct port is selected. Use the following IODD file:

TEConcept_GmbH-65539-<YYYYMMDD>-IODD1.1.xml

12. If the device is off, switch it on, enabling the L+ sup-ply of the connected master’s port by pressing the “Power ON” button keeping the light barrier closed during power-up. If the device was already powered on coming from COM2 mode, power cycle it keeping the light barrier closed to restart the device in COM3 mode. See the Light Barrier section for more information.

13. Start IO-Link communication by pressing the “IO-Link” button. The “Min. Cycle time” is set to 800µs.

14. If a different IODD file is to be selected, stop IO-Link communication first by pressing the “Inactive” button to revert the DC2227A in SIO mode.

aDDitional informationOperation in SIO Mode

The device can also operate in SIO mode. In this mode, no IO-Link communication takes place either because the master connected to the device is in the “Inactive” mode and it only supplies power to the device, or because there is no master connected to the device in which case the device is powered by a 24V supply. In SIO mode, the DC2227A reacts to the status of the light barrier as follows:

• If the light barrier is open, then drivers CQ1 and Q2 actively pull low. Since the onboard light bulb is con-nected between Q2 and ground, it is therefore turned off.

• If the light barrier is closed (by placing a piece of paper in its gap), CQ1 and Q2 actively pull high and the light bulb attached to Q2 turns on.

Temperature Sensor Configurations

In IO-Link mode, the DC2227A reports cyclically to the master (and thus to the PC Control Tool) the temperature measured by the on-board LTC2997. In order to measure temperature the LTC2997 uses an NPN configured as a diode. The NPN can be either on-chip, on PCB (Q1) or remote. Refer to the Connectors and Jumpers section for detailed information on how to choose the NPN.

Microcontroller ADC’s Offset Correction

The 12-bit ADC of the Atmel microcontroller samples both, the precise 1.8V reference voltage (VREF) and the VPTAT outputs of the LTC2997 to report the temperature in Celsius to the IO-Link master. The temperature is then calculated using a ratiometric measurement. The µC’s ADC is specified to have offsets from –40 to 40 LSBs. The temperature equation is:

100•T(°C)= ADC7 –OFFSET

ADC4–OFFSET• 45000 – 27315

ADC7 is the ADC’s code for the VPTAT output and ADC4 the code for the precise 1.8V VREF. OFFSET is the ADC’s offset (in LSB) parameter that can be set using the control tool (default is 0 LSB). In order to improve the accuracy of the temperature reading, a calibrated thermometer can be used to measure the temperature close to the LTC2997 and then the ADC Offset parameter can be set to the value (after several tries) that minimizes the error between the temperature reported by the Control Tool and that given by the calibrated thermometer.

Event Generator

The DC2227A is also equipped with a pushbutton to simulate events generated by IO-Link devices to inform IO-Link masters of requests that require special attention.

Light barrier

The light barrier offers many ways to interact with the device. It starts the device in COM3 mode if it is closed during power-up or in COM2 mode if left open. In IO-Link mode, its status is reported live on the PC control tool and in SIO mode its status is directly coupled to the CQ1 and Q2 drivers, thus allowing the user to operate the light bulb.

Light bulb

A 28V/100mA light bulb connects between Q2 and ground and serves to show the high current driving capability of the line drivers. It takes about 240ms to be turned on fully by the pulsing mechanism of the LT3669-2. To prevent data loss in IO-Link mode, driver Q2 is only enabled in between IO-Link telegrams. To turn it on and off from the control tool (in COM2 only) simply press the “Turn On” and “Turn Off” buttons within the light bulb section. In SIO mode, regardless on the IODD file chosen, the light bulb can be switched on and off by interacting with the light barrier.
