Modbus Register Assignment Of The Isometer - Bender ISOMETER isoBAT425 Manual

8. Modbus register assignment of the ISOMETER®
Depending on the device condition, the information in the registers is the measured
value without alarm; the measured value with alarm 1; the measured value with alarm 2;
or only the device error.
