RESET
The RESET function is used for example when you need to transfer the control of hardware to signals without
the need to shut down the power supply to the unit.
When the communication is activated through the first record it is necessary to communicate more
often than during 1 minute.
(the recommended communication frequency is once every 1 to 10 second)
If writing is not repeated, the situation will be considered as a MODBUS communication error (error
Er 99).
Notice: If an error is active (ER--), the registers are automatically set to "0".
Reading the values of the read registers is possible at any time without time limit and does not affect the
control by HW signals.
