3.1.2 I/O conversion characteristic

The I/O conversion characteristic represents the angle formed by a straight line connecting the "offset value" and "gain value" when the analog signals (voltage or current input) from outside the PLC are converted to digital values.

Offset value

The offset value denotes the analog input value (voltage or current) that makes the digital output value 0.

Gain value

The gain value denotes the analog input value (voltage or current) that makes the digital output value: 4000 (in normal resolution mode) 12000 (when 0 to 5 V, 1 to 5 V, 4 to 20 mA, 0 to 20 mA or the user range setting is

selected in high resol u tio n mode)

16000 (when -10 to 10 V or 0 to 10 V is selected in high resolution mode).

3.2 Function List

Table 3.2 shows the function list of the A/D converter modules.

Table 3.2 Function list

Item Function Reference section

A/D conversion enable/ disable setting

(1) Specifies whether to enable or disable the A/D conversion for each channel. (2) By disabling the conversion for the channels that are not used, the

sampling time can be shortened.

Section 3.4.2

A/D conversion method

(1) Sampling processing

The A/D conversion for analog input values is performed successively for each channel, and the digital output value is output upon each conversion.

(2) Averaging processing

For each channel, A/D conversion values are averaged for the set number of times or set amount of time, and the average value is output as a digital value.

Section 3.2.1

Maximum and minimum values hold function

(1) The maximum and minimum values of the digital output v alues is reta ined

Section 3.2.2

Temperature drift compensation function

(1) Errors arising from changes in the ambient temperature of the module are

automatically compensated for to improve conversion acc uracy.

(2) The temperature drift compensation function can be performed at (A/D

conversion time for all channels) + 160

——

Resolution mode

(1) The resolution mode can be switched according to the application, and digital-

value resolution settings of 1/4000, 1/12000 or 1/16000 can be selected. (2) The resolution mode setting is applicable to all channel s. (3) See Section 3.1.1 for the digital output values and maximum resolution in

normal resolution mode and high resolution mode.

Section 3.1.1

Section 4.5

Online module change (1) A module change is made without the system being stopped. Chapter 7

3.2.1 A/D conversion methods

There are two A/D conversion methods, sampling processing and averaging processing.

(1) Sampling processing

A/D conversion is performed successively for the analog input value, and the converted digital output values are stored in the buffer memory. The sampling processing time depends on the number of channels used (the number of channels set to A/D conversion enable) and whether the temperature drift compensation function is available.

(a) Without the temperature drift compensation function

(Processing time) = (Number of channels used )

80 ( s/1 channel)

(b) With the temperature drift compensation function

(Processing time) = (Number of channels used)

80 ( s/1 channel) + 160 s [Example] When three channel s ( chann els 1 , 2 a nd 4 ) a re A /D conv er sion e nabled with the temperature drift co mpensati on func tion, the sa mpling p rocessi ng time i s 400

80 + 160 = 400 ( s)

(2) Averaging processing

For channels for which averaging processing is specified, A/D conversion is performed for the set number of times or the set amount of time. The average value is calculated from the sum of values excluding the maximum and minimum values, and then stored in the buffer memory.

3 - 11 3 - 11

MELSEC-Q

3 SPECIFICATIONS

(a) When averaging processing is specified for the set amount of time

1) The number of processing repetitions within the set time differs according to the number of channels used (number of channels for which A/D conversion is enabled) and whether or not temperature-drift compensation is used.

• Without the temperature drift compensation function

(Set time) 1000

(Number of processing repetitions)

(Number of channels used) 80 ( s/1 channel)

• With the temperature drift compensation function

(Set time) 1000

(Number of processing repetitions)

(Number of channels used)

80 ( s/1 channel) + 160

[Example] When averaging processing is performed with four channels (channels 1, 2, 3, and 4) for the set time of 50 ms with the temperature drift compensation function on, measurement is performed 104 times and the average value is output.

50 1000

80) + 160

= 104.17 (times)

……

Round down the number.

2) When 7 or 8 channels are used with the temperature drift compensation function on, set the average time to 3 ms or more. If the time is set to 2 ms or less, the average number of times becomes less than 3 and it causes the digital output value to become 0 since a sum excluding the maximum and minimum values will be averaged.

(b) When the averaging processing is specified for the set number of times

The time required to store the average value calculated using the average number of times in the buffer memory differs according to the number of channels used (the number of channels set to A/D conversion enable) and whether or not the temperature drift compensation is used.

1) Without the temperature drift compensation function (Processing time) = (Set number of times)

{(Number of channels used) 80}/1000

(Unit: ms)

2) With the temperature drift compensation function (Processing time) = (Set number of times)

[{(Number of channels used) 80} + 160]/1000

(Unit: ms) [Example] When averaging processing is performed with four channels (1, 2, 3 and 4) for the set number of 100 times with temperature-drift compensation on, an average value i s ou tp ut eve ry 48 ms.

3.2.2 Maximum and minimum v al ues hol d function

(1) The maximum and minimum digital output values for each channel are stored in buffer

memory addresses 30 to 45 (Un\G30 to Un\G45).

(2) When the operating condition setting completed flag (X09) turns OFF, the values

are cleared to 0 and new maximum and minimum values are stored when conversion begins.

(3) Since the area for storing the maximum and minimum values can be rewritten with

the sequence program, the maximum and minimum values within a specific period of time can be checked.
