4.6.2 TROUBLESHOOTING
The TROUBLESHOOTING option is available only when the PC is communicating with a relay. It is intended to check the
ModBus communication frames between the PC and the relay. In the upper part, the user can read any readable value from
the relay (setpoints, actual values) by entering the desired hexadecimal address
i
, the type of data to read (Setpoints, Actual
Values), the number of registers (the length of each register is of 2 bytes) and the format of the data (integer, long, float...),
checking the checkbox at the left to make the PC start polling that address or unchecking it to stop.
In the lower part, data can be sent to writable addresses of the relay. The working is similar to reading but, to send the data,
the user must press the SEND button.
