5. CONNECTING I/O MODULES
5.1 INSTALLATIONThe R8 series Remote I/O modules can be used in combination with the DL8. Follow the procedure below to install I/O
modules. Refer also to the instruction manuals of respective I/O modules.

5.1.1 POINTS OF CAUTION•	Switches on the side of I/O modules must be set while the power is removed. DO NOT switch them while the power ison.
• The DL8 is usable with the R8 module address from 0 to 31. Other addresses cannot be used.
• Modules’ addresses can be chosen regardless of their mounting locations. Be sure not to use duplicated addresses.
• 4-point analog I/O module occupies 2 addresses.
e.g. When R8-SV4 is set to address 5, Input 1 and Input 2 are assigned to address 5, and Input 3 and Input 4
are assigned to address 6. In this case, do not use address 6 for other I/O modules.

5.1.2 MOUNTING■ HOW TO MOUNT THE MODULE ON DIN RAIL
• I/O Module
A

B

Confirm that the locking clamps of the I/O module are set.
Insert the module in parallel to the next one while aligning the grooves ofboth modules (A & B in the above figure).
Maintain it perpendicularly to the rail.

More I/O modules can be added in the same manner.

• Protective Cover

Groove■ HOW TO DISMOUNT THE MODULE FROM DIN RAIL
Release the locking clamps and pull out straight the module.

Hook

The protective cover is to be attached over the connected I/O module
at the right end.
Align the hooks on the cover with the grooves of the module and slide itstraight until the hooks are latched.

• Removing an intermediate module

When removing the cover, pull it out while squeezing the hooks inward.

Caution !
1) Be careful not to hurt your hand by pointed edges of the internal bus
connector.
2) I/O modules cannot hold tightly on the DIN rail by themselves without
power/network module.
Secure them to the position if necessary by using DIN rail end plates.

(sampling cycle)
Input lower than the low-end
cutout value is fixed at 0.

When the AI% data remains at 100% (10000) for the unit time period, it is converted to a preset number of pulses called “Counter Rate.”
The rectangular area in the above graphs corresponds to the Counter Rate. 1
Actual AI% value (0 to 10000) is accumulated and converted as “Accumulated Value” into the number of pulses using the Counter Rate.
The total graph area in the above graphs corresponds to the Accumulated Value. 2
The Accumulated Value is treated just like other pulse inputs, multiplied by “Scaling” into an engineering unit value.
[Example]
Flow value is sent as a voltage signal. 1 V corresponds to 0 t/h, while 5 V corresponds to 30 t/h.
In order to use analog accumulation, choose “%” as “Data Type”. 1 V at 0%, 5 V at 100%.
Choose “Hour” as “Time Unit” for the engineering unit t/h.
If “Counter Rate” is set to “30” an accumulated value of 30 is given when AI remains at 100% (5 V) for 1 hour.

DESCRIPTION
Select the number of zones to use. Selectable from: None / 2 / 3 / 4 / 5.
Input zone name (max. 64 characters).
Set a color to identify the zone on the web browser.
The boundary of each zone is defined by upper limit, lower limit, specified in engineering unit
value. Set such that the upper limit > lower limit.
• Setting deadband
When deadband is required between zone 1 and zone 2, set apart the upper limit value of zone
1 from the lower limit value of zone 2 so that the gap in between is defined as deadband.
For other zones, choose limit values in the same manner.
• No deadbands
When deadband is not required between zone 1 and zone 2, set the upper limit value of zone 1
to the same value as the lower limit value of zone 2.
For other zones, choose limit values in the same manner.
The signal entering a zone can be recorded as an event in the event log on the web browser.
Check the box to enable the event log.
Count value can be reset when it enters a zone. Check the box to enable the resetting.
Set whether to preset the pulse count as an offset for when the count is reset.
Check the box to enable [Preset overflow at reset].
Note that this function is invalid when analog accumulation value for analog input (AI) are assigned to PI.
• Positive scaling
The difference between the pulse count when the value has entered a zone and the pulse countof the lower limit value of the zone is added as an offset.
However, no offset is added when the difference is larger than the pulse count of the lower limit
value.
• Negative scaling
The difference between the pulse count when the value has entered a zone and the pulse countof the upper limit value of the zone is added as an offset.
However, no offset is added when the difference is larger than the pulse count of the upper limit
value.
Note that this function is invalid even if it is checked for a zone with the largest upper limit value
while [Reset count] remains valid for the zone.

8.8 CLOUD MODE
8.8.1 DESCRIPTIONSIn the network configuration such as 4.2.3 STYLE 3: WAN-LAN, only one DL8 device can be accessed from WAN.
For a monitoring system with more than one DL8 device, the same number of routers are required, and may result in expensive communication cost.
In order to manage such a system at low cost, “Cloud Mode” is available in addition to web server function.
Using the cloud mode, the DL8 uploads files such as HTML files required for web browsing to a web server.
Data can be browsed by specifying the URL of the web server, not the one of the DL8.
Data uploading is achieved by FTP.
The web server must have FTP server function while the DL8 acts as a FTP client.
When uploading, a subfolder for each DL8 device can be specified.
The cloud mode is also useful when many operators browse at once the web screen of single DL8 device.

16. USER DEFINED BROWSER VIEW (TYPE D & E)
16.1 GENERAL DESCRIPTIONThis section provides supplementary information for creating user defined browser views, focused on relationships between the DL8’s I/O data and web data files (.js, .json).

16.1.1 POINTS OF CAUTION
The user defined browser view function is provided for users who have technical knowledge and skill to program web files
using HTML, JavaScript, or other programming languages. HTML editor and other tools must be ready by the users, notprovided by us. Please be aware that we do not extend customer support to basic questions regarding web site programming.
The DL8 is only capable of basic web server function for file I/O handling, NOT capable of running programs such as CGI
or Script, provided from the server side.
A user defined browser view imported to the device cannot be retrieved. Please have a copy of it separately on a PC.

16.2 PROCEDURE FOR CREATING AND TRANSFERRING BROWSER VIEW DATA
16.2.1 STEP 1: CREATING A FOLDER
A user defined browser view is created on a Windows PC.
First, create a file folder.

NOTE• Be sure not to have any subfolder in the created file folder.
• File name length must be within 24 characters including its file name extension.
• Max. 1024 files can be saved in the file folder.
• Max. size per file is limited to 1 MB.
• The total file size in the folder is limited to 4 MB.

16.2.2 STEP 2: CREATING HTML FILES
Describe user’s browser views using HTML, JavaScript, CSS and other languages and save in the folder created in STEP
1.
Here is a simple example of HTML file. Write texts as shown below using a text editor tool and save it as “sample.html.”<!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.01 Transitional//EN”><html><head><meta http-equiv=”Content-Type” content=“text/html; charset=utf-8”><title></title></head><body bgcolor=”#80ffff”><p>TEST</p></body></html>MG CO., LTD. www.mgco.jp

16.3 USER DEFINED VIEW
The simple HTML file created in 16.2 PROCEDURE FOR CREATING AND TRANSFERRING BROWSER VIEW DATA,
showing only a fixed character string, is not usable for real applications.
JavaScript is usually used to realize a variable character string such as a process value indicator.
In addition, the DL8 is available with its original tags.
Modify as shown below the “sample.html” file created in 16.2 PROCEDURE FOR CREATING AND TRANSFERRINGBROWSER VIEW DATA and upload to the DL8.
Refresh the browser view.
<!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.01 Transitional//EN”><html><head><meta http-equiv=”Content-Type” content=“text/html; charset=utf-8”><title></title></head><body bgcolor=”#80ffff”><p>TEST AI1=[AI1_DATA]</p></body></html>The [AI1_DATA] part is now replaced with AI1 value.
The [AI1_DATA] is one of the original tags provided by the DL8.
A data monitoring view can be built without using JavaScript.
The DL8 original tags are usable only in .html files.
Refer to 16.4 DATA FILE SPECIFICATIONS for details of available tags.
