Confirm your selection by clicking the Add device button habdbuch the dialogue window. Now a serial port is available in the Device tree. In a similar way you can add the Ethernet port. Just select Ethernet in the Add Device dialogue instead of Modbus. If the desired interface of the SPK is supposed to function as Master, a Master device should be added to this interface in the Device tree.
For this purpose, you have to use command Add Device again by right-clicking the appropriate interface. Coddesys the Masters are available in the Device tree and they can be double-clicked for opening the configuration dialogue. Response Timeout and Socket Timeout.
The Response Timeout defines the time interval within which the Master awaits the response from the Slave. If there is no response during this interval, the next Slave is to be polled.
The defined Timeout is applied for all Slaves.
The COM interface has a similar configuration procedure, but here parameter Time between frames should be configured instead of Socket interface. The Time between Frames defines the time span which the Master awaits between the last response or timeout and the next request. When the Master devices are configured, it is time to add Slaves through the already well-known Add device dialogue window.

Now the Slaves are available in the Device tree and can be double-clicked for opening the configuration dialogue. Further settings are about specifying the communication channels. A channel is a group of register addresses which are placed one by one and are polled by only one function.
After that, a dialogue window opens where you can configure the channel. Just double-click the field of the required channel in column Variable and left-click the now available button to access Input Assistant.

Here you can take any project variable to be assigned to the channel after pressing OK. There is also a tab called Modbus Slave Init available in the configuration dialogue of any Slave device.
This tab is codesy for previous initialization of data. For instance, when it is required to set a sensor type before the data exchange is started. The procedure is similar to the channel adding. Now the Slaves are available in the Device tree and can be double-clicked for their configuring.
Codess following parameters are available:. This procedure is exactly the same like in mode Master.

After performing all the manipulations, you have just to connect hnadbuch devices to the SPK Master mode or the SPK to the master device Slave modeand check if the data exchange is correct.
Handbch — the port number of the Slave. The Slave device connected to the COM port has similar parameters: The following parameters are available: TimeOut — the waiting time with possible step size for entries of ms. The Modbus settings for the SPK are completed.
