PSsystec SMARTbox IO Agent User Guide
To connect 1 Modbus Device to the RTU network:
a. Physically wire the Modbus/RTU device through RS485 to the terminal.
b. Give the device a unique Modbus address according to the instructions provided
with the Modbus device (e.g. by setting a jumper on the device).
c. Check the serial communication settings of the device according to the instructions
provided with the device (i.e. baud rates and communication protocol). These have
to match with all devices on the bus.
d. Navigate to the terminal in Cumulocity and click on the "Modbus" tab.
e. Change the communication settings shown in the section "Serial Communication"
to match the settings on the bus, if needed.
f. Change the transmit rate and the polling rate according to your requirements. The
polling rate is the frequency at which the Modbus devices are polled for changes.
The transmit rate is the frequency where measurements are sent to CoT.
g. Click "Save changes" if you made changes.
h. To start communication between the terminal and the Modbus device, click "Add
new device".
i. Enter a name for the device and select the type of the device from the drop-down
box. To add new device types, see www.youtube.com/watch?v=99dj4PDMwQQ
below. Set the Modbus address of the connected device.
j. Click "Add". CoT will now send a notification to the SMARTbox that a new device is
ready to be managed. This may take a few seconds.
