Automation and Control - Devices and accessories >> Barix_IO12 >> IO12-Update

This page describes how to update the firmware on an IO12.

The IO12 can be updated using a Barionet and a PC/Mac using a terminal program to control the application. The terminal program can connect to the application either via network (TCP) or a serial (RS-232) connection.

Prerequisites

Prepare the following material:

• PC or Mac with e and a terminal program such as hyperterm
• Optionally: a serial port (HW or USB2serial) and a serial cross cable (DB9 femaleto DB9 female)
• A Barionet 50 (FW 2.00 or higher) or a Barionet 100 (FW 2.08 or higher)
• Modbus Test & Load BCL application (MBT_Vxx_S.cob for serial cable or MBT_Vxx_T.cob for TCP terminal)
• Power supply 9VDC (min.) to 30VDC (max.), to supply both Barionet and IO12, 300mA (min.)
• 4pin Extension cable to connect to Barionet 50 or 4 wires to connect to Barionet 100

⇒ Tips:

• Using a Barionet 50 is simpler as it needs no wiring: The supplied 4 pin extension cable can be used !
• Using the TCP version of the application is simpler as it needs no serial port and serial cable ! It works via the Ethernet network connection.

Hardware setup

1. Connect the PC/Mac and the Barionet to your network switch or hub
2. Depending on the kind of application control connection do the following:

   If you plan to use the TCP version of the application skip to step 3.

   If you plan to use the serial version of the application: Connect the PC/Mac to the serial port of the Barionet with the cross cable

3. Depending on the available Barionet wire the IO12 as following:

   If you use the Barionet 50: bridge the Barionet 50 (J10) and the IO12 (J9 or J10) using the supplied 4 pin extension cable.

   If you use the Barionet 100: As the 4 pin extension cable is NOT supported, connect the Barionet 50 to the IO12 using 4 wires via the screw block terminals as following:

J6 pin 16	Power -	J5 pin 3
J7 pin 4	RS485 A	J11 pin 1
J7 pin 5	RS485 B	J11 pin 3

Software setup

1. Connect the PC/Mac and the Barionet to your network switch or hub
2. Depending on the kind of application control connection do the following:

   If you plan to use the TCP version of the application:

   * Load the file MBT_Vxx_T.cob (xx is the version, at the time of writing: 11) into the Barionet's page WEB4 (Barionet 50: via extended web update, Barionet 100: via tftp), reboot when done and wait 10 seconds

   * Connect the PC/Mac to the serial port of the Barionet with the cross cable

   * Start a terminal program with the serial settings 9600,8,N,1 no HW control

   If you plan to use the serial version of the application:

   • Load the file MBT_Vxx_S.cob (xx is the version, at the time of writing: 11) into the Barionet's page WEB4 (Barionet 50: via extended web update, Barionet 100: via tftp), reboot when done and wait 10 seconds

   ** Connect the PC/Mac to the serial port of the Barionet with the cross cable

   ** Start a terminal program with the serial settings 9600,8,N,1 no HW control

• Wire the X8 with the Barionet and power supply as following:

Firmware Update Quick Guide

The follwing steps give a quick run down on how to update the firmware on an IO12.

1. Load a Barionet 50 or 100 with the latest Firmware
2. Connect the IO 12 to the Barionet (BA50 4pin cable, BA100 2pin power & 2pin RS-485)
3. Load the MBT application (either the T version for TCP terminal or the S for serial terminal on RS-232 into the Barionets WEB4 and reboot
4. Connect the terminal (T: open TCP terminal to Port 12345 / S: open serial Terminal 9600,8,N,1 NoHW). The terminal shows:

   Modbus and X8/R6 Test Application

   Please select: 1 for factory, 2 for service mode, 3 for loader

5. Hit the number 2 and hit the Enter (↵) key for sevice mode. The terminal shows:

   Wadr,reg,val | Radr,reg,num or | sSadr,coil,val | bBadr | Is1,s2 | Cs1,s2 | Fs1,s2 | X ?

6. To check if talking to the IO12 is possible enter R0,256,4 (capital R, zero, comma, two, five, six, comma, four) and hit the Enter (↵) key. The terminal shows:

   R0,256,4

   READ: 00B3 0008 000C 0052

   The first group of digits tells the HW Type (B3=IO12), the 2nd tells the current version (V8), the 3rd the Serial 1 (0xC=12 decimal) and the 4th the Serial 2 (0x52=82 decimal). Both serials can be found on the data plate of the IO12 !

7. Now that we know that the connection works we can start with deleting the existing firmware by entering F12,82 (capital F, serial1, comma, serial2)

   ⇒ Make sure you use the correct serial numbers 1 and 2 (decimal values not hex) of YOUR device !!!

   and hit the Enter (↵) key. The terminal shows:

   F12,82

   ?

   Wadr,reg,val | Radr,reg,num or | sSadr,coil,val | bBadr | Is1,s2 | Cs1,s2 | Fs1,s2 | X ?

   ⇒ Do NOT be fooled by the question mark. The IO12 will carry out the Erase command and after 3 seconds the PWR LED will go dark.

   • If the PWR LED stays lit then repeat step 7 carefully.
   • If after repeating step 7 the PWR LED stays lit then check if your devices production week information on the data plate (bottom of the device):

   ⇒ If it was produced on or between PW50/10 and PW03/11 then you can NOT updated the device using this MBT method !

   ⇒ If this is the case the device must be returned to Barix for factory programming.

8. Hit the X (capital X) and then hit the Enter (↵) key to exit the service mode. The terminal shows:

   Modbus and X8/R6 Test Application

   Please select: 1 for factory, 2 for service mode, 3 for loader

9. Do NOT wait and hit the number 3 and hit the Enter (↵) key for loader mode. The terminal shows:

   wrong serial setup - correcting & rebooting ..

10. After the reboot the loader mode will be started automatically. The terminal shows:

    Modbus and X8/R6 Test Application

    Please select: 1 for factory, 2 for service mode, 3 for loader

    loader started, please reset unit. Press F for erase command, S to send firmwar

11. Hit the S (capital S) and then hit the Enter (↵) key to start the firmware update. The terminal shows:

    sending firmware

    end programming

    ⇒ This will take about 20 seconds (the RS-485 LED of the Barionet will flicker) and when done the PWR LED will be lit.

    • If it stays dark power cycle the IO12 (disconnect the power wires, wait 4 seconds and reconnect power wires)
    • If it still stays dark repeaet power cycling up to 3 more times
    • If it stays dark go back to step 10 and repeat the erase command

12. Hit the X (capital X) and then hit the Enter (↵) key to exit the loader mode. The terminal shows:

    Please select: 1 for factory, 2 for service mode, 3 for loader

13. Do NOT wait and hit the number 2 and hit the Enter (↵) key for service mode. The terminal shows:

    wrong serial setup - correcting & rebooting ..

14. After the reboot the terminal shows:

    Modbus and X8/R6 Test Application

    Please select: 1 for factory, 2 for service mode, 3 for loader

15. Hit the number 2 and hit the Enter (↵) key for sevice mode. The terminal shows:

    Wadr,reg,val | Radr,reg,num or | sSadr,coil,val | bBadr | Is1,s2 | Cs1,s2 | Fs1,s2 | X ?

16. To check if the update of the IO12 went fine enter R0,256,4 (capital R, zero, comma, two, five, six, comma, four) and hit the Enter (↵) key. The terminal shows:

    R0,256,4

    READ: 00B3 000B 000C 0052

    The second group of digits tells the current firmware version (now 0xB = V11).

    ⇒ If it still says the old version then the update failed. Start over from the beginning.

Gratulations, you succesfully updated the device.
