2. Hardware configuration
The modules are parameterised using the rotary switch of the BK7300. Therefore, only the end termi-
nal must be plugged. To establish the communication with the myGEKKO you need to set the baud
rate to 38400 and watchdog to 0 ms.
Setting the baud rate to 38400:
1.
Turn off the 24V of the coupler
2.
Disconnect all terminals except the end terminal, the KL9010
3.
Set the address selection switch x10 to 3 and x1 to 1 baud rate
4.
Turn on the 24V of the coupler
5.
The coupler indicates the baud rate via the LEDs
6.
1 x flashing of the LEDs I/O RUN and I/O ERR means 38400 baud
Setting the watchdog to 0 ms:
1.
Turn off the 24V of the coupler
2.
Disconnect all terminals except the end terminal, the KL9010
3.
Set the address selection switch x10 to 6 and x1 to 0
4.
Turn on the 24V of the coupler
5.
The coupler indicates the watchdog time via the LEDs
6.
0 x flashing of the LEDs I/O RUN and I/O ERR means 0x1000ms=0ms
Setting the address of the coupler:
The address of the Modbus coupler is set via the address selection switches x10 and x1.
To set address 1 set the address selection switch x10 to 0 and x1 to 1. Caution, the ad-
dress of the Beckhoff coupler must be assigned according to the IO station number via
the IO configuration on the myGEKKO.
