Replacement procedures
Converting a project file
[Important Note]
Please backup PN4 file before converting a project file. HG4G/3G series and HG2G-5F
series can be converted to HG4G/3G/2G-V. HG4G/3G/2G-V series; however, cannot
be converted to HG4G/3G series or HG2G-5F.
[Procedures]
1. Launch WindO/I NV4 with Ver1.11.1 or later.
2. Open PN4 file. (If PN4 file is not found, then please upload the file from MICRO/I.)
3. Click on [Change Product Series] button on the status bar that is on the bottom of
the WindO/I-NV4 window.

4. Select product series for replacement from [Product Series] list.

5. Click [OK] button.

If [Set Conversion Option] in the 2nd procedure of [Converting a project file] is set to[Zooming Conversion], then size and axis of converted project’s parts get
stretched and converted accordingly to the display resolution.
(Example) Apply following settings to the text parts and convert them.
Text parts 1: Font: Japanese, Magnification: 2 x 2Text parts 2: Font: Windows (MS UI Gothic), Size: 28
Text parts 3: Font: Stroke, Size: 20↓Conversion
Text parts 1: Font: Japanese, Magnification: 2 x 2Text parts 2: Font: Windows (MS UI Gothic), Size: 34
Text parts 3: Font: Stroke, Size: 25
Following is the conversion image.

Conversion

9

・About text parts 1
Each value that represents size is multiplied accordingly to the display resolution; eachvalue is multiplied by1.28.
2 x 1.28=2.56
Since figures below decimal point are omitted, size stays at“2”after the conversion.
・About text parts 2
Each value that represents size is multiplied accordingly to the display resolution; eachvalue is multiplied by 1.28. However, if font is set to Windows font, text string’s widthand height is multiplied by 1.28, and closest size gets selected instead of multiplying thesize value. The result for above case is“34.”・About text parts 3
Each value that represents size is multiplied accordingly to the display resolution; eachvalue is multiplied by 1.28.
20 x 1.28=25.6
Since figure below decimal points are omitted, size is set to“25”.
[Important Note1]<Detail>
Placement and size of texts on the display may not be converted accordingly to theconversion rate as shown above. For this reason, texts in HG4G/3G-V series may lookdifferent compare to that of HG4G/3G series.
<Solution>
Please adjust placement and size of texts accordingly to the display size of
HG4G/3G-V.
[Important 2]<Detail>
Picture may get stretched accordingly to the display resolution. Stretched picture may
look blurry depending on the original data.
<Solution>
Please recreate images accordingly to the size of HG4G/3G-V series, then save them.

Necessity

HG4G/3G series ⇒ HG4G/3G-V series

Necessary

HG2G-5F series ⇒ HG2G-V series

Necessary[Summary]
HG4G/3G/2G-V series have better operating performance compare to that of
HG3G/4G series and HG2G-5F series. This makes scan speed much faster.
[Important Note 1]<Detail>If device addresses linked to a scan is used for performing image processing, time until
the objects starts operating and operation cycle of the objects may change. Typicaldevice addresses are shown below.
Device Address

Function

LSM4

Alternates between 0 and 1 with each scan

LSD7

Incremented at each scan

Example: A part that operates when LSD7 value equals to or greater than 10000
Since the scan speed of HG4G/3G/2G-V is faster than that of HG4G/3G/2G-5F, thetime until LSD7 reaches 10000 becomes shorter. For this reason, HG4G/3G/2G-V
objects operate at earlier timing than that of HG4G/3G/2G-5F.
<Solution>
The scan speed depends on the number of parts placed on the display and the numberof device addresses used. Please change the trigger conditions accordingly to the scan
speed of each screen.

11

[Important Note 2]<Detail>User communication checks the trigger conditions of commands for each scan. Thus,
as scanning speed becomes faster, the response to external devices may become fasteras well.
Example: User communication is set to return a response when a command is received
from an external device.

Necessary

HG2G-5F series ⇒ HG2G-V series

Necessary[Summary]
HG4G/3G/2G-V series’ corresponding expansion modules’ types and setting
methods have changed.
[Restriction]
The FC4A digital I/O module cannot be used with HG4G/3G/2G-V series. Please use
FC6A digital I/O module.
[Important Note 1]<Detail>
LEX and LEY device addresses in the project are automatically and respectively
replaced by #I and #Q device addresses at the time of conversion. Device addresses
that are written in comment for parts and scripts; however, do not get replaced
automatically.
<Solution>
Change comment for parts and scripts. Device addresses will not get replaced for WLEX
and WLEY. So please manually replace WLEX and WLEY with #WI and #WQ.
[Important Note 2]<Detail>
Module configuration dialog box has been added to WindO/I-NV4.
<Solution>
If only FC6A series digital I/O module is used, then there is no need for changing thesettings in the Module Configuration dialog box as it will operate properly. When using
FC6A series analog I/O module, open Module Configuration dialog box from [Project
Settings]-[Expansion Modules]. Then select FC6A series analog I/O module to connect
and download project to HG4G/3G/2G-V series.

Necessary

HG2G-5F series ⇒ HG2G-V series

Unnecessary[Summary]
There is no more audio input, and playable video format has been changed.
[Restriction]
Audio cannot be recorded while recording.
[Important Note 1]
HG4G/3G series video interface equipped model’s file format is MP4 file, but the fileformat for HG4G/3G-V series is changed to AVI file.
<Solution>
When using MP4 file that was used on HG4G/3G video interface equipped model, on
HG4G/3G-V series, convert MP4 file to AVI file using file conversion software. Please
read the instruction on next page for using Avidemux. Avidemux is free software thatcan be downloaded from the following URL.
(http://avidemux.sourceforge.net/download.html)

14

Procedures for converting MP4 file to AVI file

1. Launch Avidemux and select MP4 file from [File]-[Open].

2. Change the setting on the left side of Avidemux as follows.
Video Output: Mjpeg Encoder
Audio Output: PCM
Output Format: AVI Muxer
3. Select [File]-[Save] and save as AVI file.

[Important Note 3]
The volume of the HG4G/3G-V series' sound function and playback function is louder
than that of the HG4G/3G series. Therefore, even if the volume value (minimum: 0
maximum: 31), which is specified by the device address in “Change Volume Level” ofSound Settings, is the same, HG4G/3G-V series sounds louder. Following is the setting
for making both series sound volume about the same.
HG4G/3G series volume level

Volume level 31

Volume level 7 to 8

Volume level 15

Volume level 2 to 3

<Solution>
Adjust the device address value in “Change Volume Level” of Sound Setting. Also,
adjust the volume of the speaker or amplifier connected to the audio output terminal.
