1. Electrical outlet
The bus terminal system is the universal interface between eld bus system and the sensor / actua-
tor level. A unit consists of a bus coupler as head station, and up to 64 electronic series terminals, the
last one being an end terminal. For any technical signal form terminals are available, each having two
input/output channels, which can be mixed.

Warning!! The Beckho coupler only works if it is
the only one on the interface, i.e. no other IO sta-
tions may be operated on the same interface as
well as only one Beckho coupler via bus.

Connection to the myGEKKO
The Beckho coupler is connected to a RS485
interface. It can be connected either directly to
the RS485 interface on the myGEKKO Touch or via
a RS232/RS485 interface converter. This interface
converter can be connected to either the free
interface directly on the myGEKKO Touch or the
interface distributor USB/quadruple RS232 (Art. nr.
ACC-RS201). A maximum of 5 interfaces are avail-
able on a myGEKKO Touch with distributor.
Jumper SW1 (485-2W)
must be in position ON!
Interface converter
RS232/RS485 Art. ACC-RS401
Recommended cable type for the RS485 bus connection line is: Probus L2FIP 1x2x0.65
Connection of bus line RS485 on the bus coupler via included ProBus connector.
Caution: Activation of the terminating resistor on the bus coupler at the end of the bus line.

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 Beckho coupler must be assigned according to the IO station number via
the IO conguration on the myGEKKO.
2. Hardware conguration
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:
Turn o the 24V of the coupler1.
Disconnect all terminals except the end terminal, the KL90102.
Set the address selection switch x10 to 3 and x1 to 1 baud rate3.
Turn on the 24V of the coupler4.
The coupler indicates the baud rate via the LEDs5.
1 x ashing of the LEDs I/O RUN and I/O ERR means 38400 baud6.
Setting the watchdog to 0 ms:
Turn o the 24V of the coupler1.
Disconnect all terminals except the end terminal, the KL90102.
Set the address selection switch x10 to 6 and x1 to 03.
Turn on the 24V of the coupler4.
The coupler indicates the watchdog time via the LEDs5.
0 x ashing of the LEDs I/O RUN and I/O ERR means 0x1000ms=0ms6.

Parameterisation table for further settings of the modules
After connecting the Beckho modules you can start with the conguration.
Log in as congurator.
Change to the system menu -> IO conguration1.
Select the rst free IO station and set Modbus. (The address of the coupler and the number of2.
the IO station must match)
Select the interface.3.
The baud rate must be 38400.4.
Reg In Start is 0, Reg Out Start is 20485.
Save under Reg In Digital or Reg Out Digital the digital inputs or outputs and under Reg In6.
Analogue or Reg Out Analogue the analogue inputs or outputs
Reg Order must be selected Analogue+Digital7.
