RUN Green Lit when the Analog Input Unit is operating correctly. If operation is not normal, this

indicator turns OFF and Unit operation is stopped.

BROKEN WIRE Red Lit when an input signal wire is disconnected. This indicator operates only when the

input range is set to 1 to 5 V/4 to 20 mA.

Functions The following table briefly outlines the basic functions of the C200H-AD002.

These

functions are covered in more detail in

Function Explanation

Conversion prohibit setting Unnecessary conversion processing time can be reduced by disabling analog-to-digital

conversion for unused inputs. Disabling conversion can also reduce the sampling period for each input.

Input range setting The input range can be set for each input number according to the input signal level

that is to be used. Conversion data type setting Sets whether the converted digital output is BCD or binary. Square root Converts quadratic data, such as thermocouple input, to linear data. Scaling Converts an analog input signal to a preset range of BCD data for output. Mean value Sums the sampling data for the specified number of samples, eliminates the minimum

and maximum values, calculates the mean value from the remaining values, and

outputs that value. Peak value Holds the maximum values for A/D conversion data, scaling data, mean data, and

square root data, and outputs them as output data. Limit warning The Warning Flag is turned ON if the A/D conversion data, scaling data, mean data, or

square root data exceeds the specified upper- or lower-limit values. Disconnection detection The Disconnection Detection Flag is turned ON and the BROKEN WIRE indicator is lit if

the input signal wire becomes disconnected when 1 to 5 V/4 to 20 mA are set.

Input Wiring Considerations

When wiring inputs, apply the following points to avoid noise interference and optimize Analog Input Unit performance.

• Use shielded twisted-pair cable for external connections and power lines.

• Route input cables separately from the AC cable, and do not run the Unit’s

cables

near a main circuit cable, high voltage cable, or a non-PC load

cable.

• Be sure to install surge-absorbing diodes or surge absorbers for inductive

loads (relays, solenoids, electromagnetic valves, etc.) They should be installed

right next to relays and solenoids. Use surge-absorbing diodes with a

dielectric strength of at least five times the circuit voltage.

DC Relay

Surge-absorbing diode

Solenoid, etc.

AC Relay

Surge absorber

• If

there is noise interference from power lines (if, for example, the power supply

shared with electrical welding devices or electrical discharge machines, or if

there

is a high-frequency generation source nearby) install a noise filter at the

power supply input area.

• Connect

to a ground of 100 Ω or less, with as heavy a wire as possible (i.e., at

least 1.25 mm2).

Output Wiring Considerations

wiring outputs, apply the following points to avoid noise interference and

optimize Analog Output Unit performance.

• Use shielded twisted-pair cable for external connections and power lines.

• Route output cables separately from the AC cable, and do not run the Unit’s

cables

near a main circuit cable, high voltage cable, or a non-PC load

cable.

• Be sure to install surge-absorbing diodes or surge absorbers for inductive loads (relays, solenoids, electromagnetic valves, etc.) They should be installed

right next to relays and solenoids. Use surge-absorbing diodes with a

dielectric strength of at least five times the circuit voltage.

DC Relay

Surge-absorbing diode (Example: ERB44-06, by Fuji Electric)

Solenoid, etc.

Surge absorber (Example: CR-50500, by Okaya Electric)

• If

there is noise interference from power lines (if, for example, the power supply

shared with electrical welding devices or electrical discharge machines, or if

there

is a high-frequency generation source nearby) install a noise filter at the

AC Relay

Surge absorber (Example: CR-50500, by Okaya Electric)

power supply output area.

• Connect

to a ground of 100 Ω or less, with as heavy a wire as possible (i.e., at

least 1.25 mm2).

the Analog Output Unit.

Word Allocation This program example uses the following settings:

• Unit number: 0 (Words IR 100 to IR 103 are allocated to unit number 0.)

• The following table shows the DM words that contain the output data.
