Specifications
Section 6-1
2.
The maximum number of Analog I/O Units that can be mounted to one
Rack will varies depending on the current consumption of the other Units
mounted to the Rack.
3.
Input and output signal ranges can be set for each input and output.
4.
Voltage input or current input are chosen by using the voltage/current
switch at the back of the terminal block.
5.
The Analog I/O Unit must be operated according to the input specifications
provided here. Operating the Unit outside these specifications will cause
the Unit to malfunction.
6.
The accuracy is given for full scale. For example, an accuracy of
±
0.2%
means a maximum error of
±
8 (BCD).
The default setting is adjusted for voltage input. To use current input, per-
form the offset and gain adjustments as required.
7.
A/D conversion time is the time it takes for an analog signal to be stored in
memory as converted data after it has been input. It takes at least one cy-
cle before the converted data is read by the CPU Unit. D/A conversion time
is the time required for converting and outputting the PLC data. It takes at
least one cycle for the data stored in the PLC to be read by the Analog I/O
Unit.
8.
When the operation mode for the CPU Unit is changed from RUN mode or
MONITOR mode to PROGRAM mode, or when the power is turned ON,
the Output Conversion Enable Bit will turn OFF. The output status specified
according to the output hold function will be output.
9.
Input disconnection detection is valid only when the 1 to 5-V or 4 to 20-mA
range is set. If there is no input signal for when the 1 to 5-V or 4 to 20-mA
range is set, the Disconnection Detection Flag will turn ON.
