where C
n
is the numerical count and V
ao
is the analog output voltage.
Data Format 0to10VDC
In an ideal linear voltage representation for 0 to 10 VDC range, a value of 32 001
represents an OVW. If the output value is less than or equal to 767, the module
reports a UVW. When the output value reaches 32 767, an OVE occurs. When the
output value reaches 0, a UVE occurs.
An ideal linear voltage representation is interpreted using the formula:
