calculated as follows:
<w> = ([D0] x <1> + [D1] x <2> ) +...+ ([D11] x <2048>)
Holding register 61
(A set bit is indicated by
on the right of number):

8.6 Error alarms
Error alarms can be sent over a modem either directly to the control station or over the SMS text
message function to a mobile phone or to a fax. Just one function (Modbus, SMS function or fax
function) can be selected at one time since the functions use the same interface. The error alarms
to a mobile phone and to a fax contain the number of the affected error status register (FSR1),
the fault as per error status register (BitNo), the controller ID and the bit number (Bit xx).
