31007715 6/2008
Data Formats 0 to 5 VDC and +1 to 5 VDC
In an ideal linear voltage representation for +1 to 5 VDC range, a value of 32 001
represents an OVW. If the output value is less than or equal to - 1, the module
reports a UVW. When the output value reaches 32 767, an OVE occurs. When the
output value reaches - 767, a UVE occurs.
Output voltage (in V) is given by the following formula:
V
ao
= C
n
/8000 + 1
where C
n
is the numerical count and V
ao
is the analog output voltage.
In an ideal linear voltage representation for 0 to 5 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:
V
