To avoid any problems please maintain 1A 12V on the TX Modbus power terminal block
In the CONFIG TX tab , refresh your browser page. A green validation dot should appear in front of the TX Modbus slaves that you have just activated. A red dot means that the configuration is being recovered. Do not hesitate to wait a few moments and refresh your page if the green dots do not appear.
In the “NETWORK” tab, the frames containing the contents of the slave registers read by the Modbus TX that you have just activated must be sent at the periodicity that has been configured. This tab allows you to validate the correct reception of Modbus TX frames
We recommend using this page as an on-site audit tool, to validate that RSSI levels for receiving frames are good
Click on the “MODBUS” tab. When you select a slave on the left of the screen, the registers in which its information is stored are displayed in the Modbus Table. You can save this Modbus table with the “Export CSV” button.
It is possible to write to the Modbus table registers for each slave.
Writing can only be done on “Hold” or “Coil” type registers.
You can check if the slave registers have been read and written by consulting this article: [Proprietary mode] Verification of reading/writing of TX Modbus registers
Step 1
Power the TX Modbus (7.5 to 24VDC)
Step 2
Validate the TX Modbus LEDs behavior
Open the TX Modbus case by unscrewing the 4 cover screws then externally power your TX Modbus (between 7.5 to 24VDC).
When you power it, the TX Modbus tries to communicate with the receiver. You can refer to the TX Modbus LEDs to learn more about the installation status.
