Hello,
I must display datas from an energymeter schneider PM210 connected with modbus.
communication is ok with the read_var function block.
I just have difficulties to retrieve the floating values from 2 integers given by the modbus registers.
eg: P(kW) = -11.432
whalso values transmitted on one 16bit register are not directly displayable
my question is:
is there a documentation which would explain how decoding modbus 16 bits registers to retrieve readable values. ??
thanks in advance
