Wiring for Current Input
When using current input, short-circuit the input (+) terminal and the current
mode terminal.
3. Input the voltage or current so that the conversion value is maximized
(0FA0 or 07D0 at a resolution of 4,000). The following table shows the gain
adjustment voltages and currents to be input according to the input signal
range.
(Values in parentheses are for a resolution of 8,000.)
4. With the voltage or current having been input so that the conversion value
for the Analog Input Unit is maximized (0FA0 or 07D0), turn bit 04 (the Set
Bit) of CIO word n+1 ON and then OFF again.
While the Gain Bit is ON, the gain value will be saved to the Unit’s EE-
PROM when the Set Bit turns ON.
Input signal range Input range Word (n+8) monitoring value
