from December 1st, 1998 FX2N-2DA

Caution for EC Directive

The FX2N-2DA have been found to be compliant to the European standards in the aforesaid manual and

directive. However, for the very best performance from what are in fact delicate measuring and controlled

output device Mitsubishi Electric would like to make the following points;

As analog devices are sensitive by nature, their use should be considered carefully.

For users of proprietary cables (integral with sensors or actuators), these users should follow those

manufacturers installation requirements.

Mitsubishi Electric recommend that shielded cables should be used. If NO other EMC protection is

provided, then users may experience temporary loss or accuracy between ±10% in very heavy industrial

areas.

However, Mitsubishi Electric suggest that if adequate EMC precautions are followed for the users

complete control system, users should expect accuracy as specified in this manual.

• Sensitive analog cable should not be laid in the same trunking or cable conduit as high voltage

cabling. Where possible users should run analog cables separately.

• Good cable shielding should be used. When terminating the shield at Earth - ensure that no earth

loops are accidentally created.

1. INTRODUCTION

The FX2N-2DA type analog output block (hereafter referred to as the FX2N-2DA) is used to convert a

digital value of 12 bits into an analog output of two points (voltage and current output), and to forward the

values to the Programmable Controller (hereafter referred to as a PLC).

FX2N-2DA can connected to the FX0N, FX1N, FX2N, FX2NC, FX3G, FX3GC, FX3U, and the FX3UC series

Programmable Controllers.

1) The analog output is selected from the voltage or current output by the method of connecting wires.

At this time, assume setting to be two channels common analog output.

2) The two analog output channels can accept outputs of 0 to 10V DC, 0 to 5V DC, or 4 to 20mA.

(A mixture of voltage/current output is possible.)

3) Resolution is 2.5mV (0 to 10V DC) and 4µA(4 to 20mA).

4) The digital to analog conversion characteristics can be adjusted.

5) The block occupies 8 I/O points which can be allocated from either the inputs or outputs.

6) The data transfer with the PLC uses the FROM/TO instructions.

FX3U/FX3UC series PLC can use direct specification of buffer memory.

7. ADJUSTMENT OF OFFSET AND GAIN

7.1 Change in output characteristic

At shipment, 0 to 4000 range is selected for 0 to 10V DC output.

When using an FX2N-2DA for current or differing voltage output except 0 to 10V DC, it is necessary to

readjust the offset and gain.

The output characteristic can be set for each of the two channels.

Set analog values within the range specified in the table below when changing the output characteristic.

Range of output characteristic

Resolution changes depending on the set value when the output characteristic changes accordingly.

Example: Resolution becomes (5 - 0V)/4000=1.25mV at voltage output 0 to 5V/0 to 4000.

Integrated accuracy does not change. (Voltage output: ± 0.1V, Current output: ± 0.16mA)

7.2 Adjustment of the output characteristic

The adjustment of the offset and gain values sets a digital equivalent to the analog data.

(The “POT” requires 18 revolutions to move between MIN and MAX setting.)

*1 The analog value increases if the volume is turned clockwise.

7.2.1 Adjustment of gain

The gain value can be set to an arbitrary digital value.

However, using the maximum of 12bit resolution provides the user with a full scale analog value.

7.2.2 Adjustment of offset

The offset value in the case of voltage output is 0V. The offset value in the case of current output is 4mA.

However, the offset value can be minutely adjusted if necessary. Set the following when minute

adjustments are necessary.

For instance, when a digital range of 0 to 4000 is used with the analog range of 0 to 10V, a digital value of

40 is equal to an analog output of 100mV, (40 × 10V/4000 digital points). When a digital range of 0 to 4000

is used with the analog range of 4 to 20mA, a digital value of 0 is equal to an analog output of 4mA.

1) Adjust the offset and gain respectively for CH1 and CH2.

2) Repeat offset and gain adjustments until a stable value is obtained.

3) Adjust the gain before the offset.

Caution for EC Directive

The FX2N-2DA have been found to be compliant to the European standards in the aforesaid manual and

directive. However, for the very best performance from what are in fact delicate measuring and controlled

output device Mitsubishi Electric would like to make the following points;

As analog devices are sensitive by nature, their use should be considered carefully.

For users of proprietary cables (integral with sensors or actuators), these users should follow those

manufacturers installation requirements.

Mitsubishi Electric recommend that shielded cables should be used. If NO other EMC protection is

provided, then users may experience temporary loss or accuracy between ±10% in very heavy industrial

areas.

However, Mitsubishi Electric suggest that if adequate EMC precautions are followed for the users

complete control system, users should expect accuracy as specified in this manual.

• Sensitive analog cable should not be laid in the same trunking or cable conduit as high voltage

cabling. Where possible users should run analog cables separately.

• Good cable shielding should be used. When terminating the shield at Earth - ensure that no earth

loops are accidentally created.

1. INTRODUCTION

The FX2N-2DA type analog output block (hereafter referred to as the FX2N-2DA) is used to convert a

digital value of 12 bits into an analog output of two points (voltage and current output), and to forward the

values to the Programmable Controller (hereafter referred to as a PLC).

FX2N-2DA can connected to the FX0N, FX1N, FX2N, FX2NC, FX3G, FX3GC, FX3U, and the FX3UC series

Programmable Controllers.

1) The analog output is selected from the voltage or current output by the method of connecting wires.

At this time, assume setting to be two channels common analog output.

2) The two analog output channels can accept outputs of 0 to 10V DC, 0 to 5V DC, or 4 to 20mA.

(A mixture of voltage/current output is possible.)

3) Resolution is 2.5mV (0 to 10V DC) and 4µA(4 to 20mA).

4) The digital to analog conversion characteristics can be adjusted.

5) The block occupies 8 I/O points which can be allocated from either the inputs or outputs.

6) The data transfer with the PLC uses the FROM/TO instructions.

FX3U/FX3UC series PLC can use direct specification of buffer memory.

Warranty

Exclusion of loss in opportunity and secondary loss from warranty liability

Regardless of the gratis warranty term, Mitsubishi shall not be liable for compensation to:

(1) Damages caused by any cause found not to be the responsibility of Mitsubishi.

(2) Loss in opportunity, lost profits incurred to the user by Failures of Mitsubishi products.

(3) Special damages and secondary damages whether foreseeable or not, compensation for

accidents, and compensation for damages to products other than Mitsubishi products.

(4) Replacement by the user, maintenance of on-site equipment, start-up test run and other tasks.

7. ADJUSTMENT OF OFFSET AND GAIN

7.1 Change in output characteristic

At shipment, 0 to 4000 range is selected for 0 to 10V DC output.

When using an FX2N-2DA for current or differing voltage output except 0 to 10V DC, it is necessary to

readjust the offset and gain.

The output characteristic can be set for each of the two channels.

Set analog values within the range specified in the table below when changing the output characteristic.

Range of output characteristic

Resolution changes depending on the set value when the output characteristic changes accordingly.

Example: Resolution becomes (5 - 0V)/4000=1.25mV at voltage output 0 to 5V/0 to 4000.

Integrated accuracy does not change. (Voltage output: ± 0.1V, Current output: ± 0.16mA)

7.2 Adjustment of the output characteristic

The adjustment of the offset and gain values sets a digital equivalent to the analog data.

(The “POT” requires 18 revolutions to move between MIN and MAX setting.)

*1 The analog value increases if the volume is turned clockwise.

7.2.1 Adjustment of gain

The gain value can be set to an arbitrary digital value.

However, using the maximum of 12bit resolution provides the user with a full scale analog value.

7.2.2 Adjustment of offset

The offset value in the case of voltage output is 0V. The offset value in the case of current output is 4mA.

However, the offset value can be minutely adjusted if necessary. Set the following when minute

adjustments are necessary.

For instance, when a digital range of 0 to 4000 is used with the analog range of 0 to 10V, a digital value of

40 is equal to an analog output of 100mV, (40 × 10V/4000 digital points). When a digital range of 0 to 4000

is used with the analog range of 4 to 20mA, a digital value of 0 is equal to an analog output of 4mA.

1) Adjust the offset and gain respectively for CH1 and CH2.

2) Repeat offset and gain adjustments until a stable value is obtained.

3) Adjust the gain before the offset.
