IO12 tunnel application
This working application allows transport an input signal from a local IO12 to an output of the remote IO12.
Two Barionet with upto 7 connect IO12 modules can exchange IO status information (from connected IO12s only!).
The Barionet will poll permanently the input state of the connected IO12 modules, when an input state has changed it will send the answer from the IO12 to the remote Barionet
which will change the according output of the connected IO12 with the same modbus address to the same state.
When multiple IO12 extensions are connected to the Barionet then please use the "Modbus addressing page" to assign an unique Modbus address to each IO12 extension device.
When the "Show Output state" parameter is enabled then the output state of the connected IO12 modules is displayed on this web page.
Green button means state = 1 = on
White/gray button means state = 0 = off
Required Barionet serial setup
RS485
Serial Speed = 19200
Parity bit = enable even
Stop bit = 1 Data bits = 8 local port = 0
How to wire the IO12 to the Barionet ?
You have to power your IO12 as in the IO12 manual described. The power for one IO12 you can take also from the Barionet itself
(e.g. from J4 or J5 of the Barionet to J9 of the IO12).
For the data line (RS485) use the following wiring :
Barionet - IO12
pin 4 of J7 to pin 2 of J11
pin 5 of J7 to pin 3 of J11
For the Barionet50 it only needs the 4 pin daisy chain cable from Barionet50 - J1 to J9 of the IO12.
Also use the 4-wire daisy chain cable to connect the first IO12 to the second IO12 and so on.
Beside that the IO12 communication status can be checked on Barionet registers 301 (for Modbus address 255) until 307 (for Modbus address 249, state 1 (green) means communication is ok.
