1. Electrical outlet

The bus terminal system is the universal interface between field 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.

Input current 70 mA + (total K-bus current)/4, 500 mA max.

Starting current 2,5 x Dauerstrom

Number of Bus Terminals 64

Digital peripheral signals 256 In- / Outputs

Warning!! The Beckhoff 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 Beckhoff coupler via bus.

Connection to the myGEKKO The Beckhoff 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: Profibus L2FIP 1x2x0.65

Connection of bus line RS485 on the bus coupler via included ProfiBus 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 Beckhoff coupler must be assigned according to the IO station number via the IO configuration on the myGEKKO.

2. Hardware configurationThe 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 off 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 flashing of the LEDs I/O RUN and I/O ERR means 38400 baud6.

Setting the watchdog to 0 ms:

Turn off 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 flashing of the LEDs I/O RUN and I/O ERR means 0x1000ms=0ms6.

Parameterisation table for further settings of the modules

After connecting the Beckhoff modules you can start with the configuration.

Log in as configurator.

Change to the system menu -> IO configuration1. Select the first free IO station and set Modbus. (The address of the coupler and the number of 2. 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 In 6. Analogue or Reg Out Analogue the analogue inputs or outputsReg Order must be selected Analogue+Digital7.
