entering the module during wiring. Do not remove the film during wiring. Remove it for heat dissipation before system operation.

[Startup and Maintenance Precautions]

CAUTION

Do not disassemble or modify the modules.

Doing so may cause failure, malfunction, injury, or a fire.

Shut off the external power supply for the system in all phases before mounting or removing the module.

Failure to do so may cause the module to fail or malfunction. A module can be replaced online (while power is on) on any MELSECNET/H remote I/O station or in the system where a CPU module supporting the online module change function is used.

Note that there are restrictions on the modules that can be replaced online, and each module has its predetermined replacement procedure. For details, refer to the relevant chapter in this manual.

After the first use of the product, do not mount/remove the module to/from the base unit, and the terminal

block to/from the module more than 50 times (IEC 61131-2 compliant) respectively. Exceeding the limit of 50 times may cause malfunction.

Do not touch any terminal while power is on.

Doing so may cause malfunction.

Shut off the external power supply for the system in all phases before cleaning the module or retightening

the terminal screws or module fixing screws. Failure to do so may cause the module to fail or malfunction. Undertightening the screws can cause drop, short circuit, or malfunction.

Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.

(3) Switching resolution mode

A resolution can be selected from a normal resolution mode (1/4000) and high

resolution mode (1/12000 or 1/16000).

* 2 Set in Switch setting for I/O and intelligent function module dialog box.

(4) Scaling function

Digital output values can be converted to scaling values (ratio (%)) and the converted values can be stored into buffer memory. In D/A conversion, an input range of digital input values can be changed to a setting range and the analog output can be performed.

(5) Shifting function

In A/D conversion, a given value is added to an A/D converted digital output value. In D/A conversion, a given value is added to a digital input value and an analog value is output. Changing a shifting quantity reflects the output value in real time. Therefore, the output value can be adjusted with the shifting function when the CPU is powered on.

(6) Input range extended mode function

The analog input range, 4 to 20mA and 1 to 5V can be increased to the input range of

0 to 22mA and 0 to 5.5V, respectively. A/D conversion can be performed even if the input range falls below 4mA or 1V, when sensors do not measure concrete values. Combining the input range extended mode function and input signal error detection function detects a disconnection.

The device numbers (X or Y) and buffer memory addresses described in this chapter are used for CH1. (The device numbers and buffer memory addresses specified in D/A conversion are used for CH5.) For the device numbers and buffer memory addresses used for other channels, refer to Section 5.1 and Section 6.1.

4.1 Function List

Table 4.1 lists the functions of the Q64AD2DA.

Item Function

(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. The value is stored in buffer memory.

(2) Averaging processing

The digital output value is averaged on a channel basis and the averaged value is stored in buffer memory. The averaging processing has three methods as follows:

(a) Time average

(b) Count average

(1) This function retains the maximum and minimum values of the digital

output values and scaling values in the module.

(2) The retained values can be reset in any timing.

This function converts digital output values to scaling values and stores the converted values into buffer memory. Time to configure a program for scaling can be decreased.

The digital output value can be adjusted easily with the shifting function when the CPU is powered on. The shifting function adds a setting quantity to a digital output value and stores the value into buffer memory.

This function detects voltage or current input values exceeding the setting ranges. A channel set to averaging processing can be checked every sampling processing.

This function increases input ranges. Combining the input range extended mode function and input signal error detection function detects a disconnection.

This function performs logging of the digital values that A/D conversion is performed. Logging data can be stored up to 10000th data point and time-series data that A/D conversion is performed can be referred and stored easily.

4.2 Function Details of A/D Conversion

4.2.1 A/D conversion methods

(1) Sampling period of the Q64AD2DA

A/D conversion is performed from CH1 to CH4 and D/A conversion is performed from CH5 to CH6 in series in 500 s per channel for the Q64AD2DA. Sampling period is the period of renewing digital output values. The period of renewing digital output values varies depending on the total number of channels enable A/D conversion and D/A conversion.

(2) Sampling processing

A/D conversion is made successively for analog input values, and the converted digital output values are stored in buffer memory.

(3) Averaging processing

Averaging processing requires at least two times of conversion processing excluding the maximum and the minimum values. After the first averaging processing is completed, A/D conversion completed flag (XE) is set to on.

If the input range extended mode function, scaling function (for A/D conversion), and shifting function (for A/D conversion) are used simultaneously, the scaling value can exceed the range from -32768 to 32767. In such a case, the values set within the upper limit (32767) and lower limit (-

32767) values will be stored into the buffer memory as scaling values.

POINT

FUNCTION

(3) Disconnection detection

Combining the input range extended mode function and input signal error detection function detects a disconnection. If the input analog current value changes to 2mA or less, or the input analog voltage value changes 0.5V or less, an external wiring is disconnected, and CH1 Input signal error detection flag (Un\G114) is set to on (1).

(a) Setting methods

1) Disconnection detection can be performed only when the input range is set to either:

• 4 to 20mA (Extended mode)

• 1 to 5V (Extended mode)

2) To use the disconnection detection function, set CH1 Input signal error detection setting (Un\G20) to detect disconnections (4), and set Operating condition setting request (Y9) to on.

SYSTEM

OVERVIEW

CONFIGURATION

(b) Operation for disconnection detection

1) If the conditions described in Table 4.5 are satisfied, the following operations perform.

• Input signal error detection signal (X7) is set to on.

• CH1 Input signal error detection flag (Un\G114) is set to on (1).

• ALM LED blinks. To disable the above operations, cancel the conditions of disconnection detection shown in Table 4.5 and set Error clear request (YF) to on.

Table 4.5 Condition of disconnection detection

Input range Condition of disconnection detection

4 to 20mA (Extended mode)

1 to 5V (Extended mode)

2) A digital output value immediately before the disconnection detections is held for CH1 Digital output value (Un\G100), and CH1 A/D conversion completed flag (Un\G113) is set to off (0).

3) When the disconnection is restored, A/D conversion resumes independently and CH1 A/D conversion completed flag (Un\G113) is set to on (1) after the first updating.

The disconnection detection is executed at every sampling processing regardless of the status of CH1 Averaging process method setting (Un\G1). [Example] When the number of conversion enabled channels is three, the

disconnection detection is executed every 1.5ms. 500 s 3CH 1500 s 1.5ms

4.2.7 Logging function

(1) Logging function

This function collects the data of the digital output value or scaling value performed A/D conversion at a preset timing in series. This function is useful to check the data change of the digital output value or scaling value performed A/D conversion periodically because the function sets an interval (logging period), performs logging, and stores the logs into the buffer memory. In addition, this function is useful to check the data change of the analog input value during the stopped logging, if a trigger condition is set by using a hold trigger.

(2) Logging operation

When logging starts in sequence programs, logging data are stored into the logging data storage areas in order from the initial area. Logging data can be stored up to 10000th data point area for a channel. The stored data are retained until when the CPU module is powered off or Operating condition setting request (Y9) is set to on.

(b) Hold trigger

Hold trigger is the trigger that occurs for the case of preset trigger conditions to be met when a logging facility is used. When the Q64AD2DA detects a hold trigger, the logging facility stops (hold) collecting logging data after logging the number of preset points.

The necessary setting items vary depending on hold triggers to be used. Select one of two types of hold trigger.

1) For holding logging in given timing A hold trigger is detected by using Logging hold request (Y1). Setting CH1 Logging hold request (Y1) to on holds the logging.

(b) Precautions

To refer to logging data during data logging, pay attention to the following.

1) Logging cycle setting Before logging data are updated, set a cycle allows data to be referred and collected, completely and securely.

2) Reference timing After the number of logging data to be referred is collected, the oldest pointer or the change of the logging data points must be monitored and logging data must be obtained according to the change of the storage values.

If the relationship between the logging cycle and the scan time of the CPU modules causes data not to be updated and referred simultaneously, adjust the logging cycle. A short logging cycle may cause logging data to be updated in referring or collecting data. To refer to data regardless of the logging cycle, perform logging hold.

FUNCTION

The following conditions should be satisfied when the analog output HOLD/ CLEAR function is used on a MELSECNET/H remote I/O station.

• The master module of function version D or later and the remote I/O module of function version D or later are required.

• Validate the station unit block guarantee of the send side cyclic data.

• The setting for holding the Q64AD2DA output in the case of a link error must be made in the "Error time output mode in the I/O assignment setting". (Refer to Section 7.5.1 (2).). At this time, the HOLD/CLEAR setting in "Switch 3" of Switch setting for I/O and intelligent function module dialog box is not reflected. This setting is validated on a permodule basis, and is not made on a per-channel basis. Therefore, to make the output status at a stop error or STOP of the CPU module matched with the output status at a link error, set the same HOLD/CLEAR function setting to all channels.

This function changes an input range of digital input values to a given range between 32000 and 32000.

(1) Overview

(a) Whether using the scaling function (D/A conversion) for each channel or not can

be specified with CH5 D/A conversion scaling enable/disable setting (Un\G810).

Since this digital input value is out of the scaling range (1000 to 6000) set, an error (error code: 003) occurs.

FUNCTION

As indicated in the formula of (4) in this section or Figure 4.16, the value exceeding the D/A conversion scaling upper limit or the value that falls below the D/A conversion lower limit can be set for a digital input value. However, the analog output value corresponding to the real conversion digital value, exceeding the range cannot be ensured. Moreover, when setting the values of settable upper and lower limits, the real conversion digital value could not reach the maximum or minimum value.

(5) Precautions

(a) Use of scaling function (D/A conversion) and resolution

Even if the digital input value range is enlarged with the scaling function (D/A conversion), the resolution will not be more than the one applied when the scaling function is not used. As the digital input value range is narrowed, the resolution is lowered.

(b) When a digital input value range not including zero (0), such as 1000 to 6000, is

specified When a digital input value range not including zero (0), such as 1000 to 6000, is specified, set CH5 Output enable/disable flag (Y5) to on after setting values within the input range in CH5 Digital input value (Un\G802). If CH5 Output enable/disable flag (Y5) is set to on with the default value (0) set in

CH5 Digital input value (Un\G802), an error (error code: 003) will occur.

32767.

• If a scaling function (for D/A conversion) is used simultaneously, scaling will be performed after shifting.

• If the shifted values exceed the range from -32768 to 32767, the values will be fixed to the upper limit (32767) and lower limit (-32768), respectively.

• CH5 Real conversion digital value (Un\G902) indicates a digital input value that scaling and shifting are performed. (Refer to Section 4.3.4.)

• If the shifted values exceed the settable digital ranges corresponding to the set output ranges, the D/A conversion will be performed according to Table 4.15.

• Changing the shifting amount to input value reflects the analog output value in real time. Therefore, the analog output value can be adjusted with the shifting function when the CPU is powered on.
