Status
In 16 bit mode the measuring values of the individual sub channels are
represented in the output data range of the PLC as follows:
Byte address
MSB
LSB
0
Meas. value sub channel

Byte 1
Byte 0
2
Meas. value sub channel
2
Byte 1
Byte 0
4
Meas. value sub channel
3

Byte 0
The measuring status is always set to zero in 16 bit mode.
CAUTION
If the ML77B uses output data, there always has to be at least one measuring
channel in the configuration!
