*In serial/CPU port communication if different parameter is set in the same port, the first one will be valid.
NETWORK No
Specify the network number set in PLC if you use Ethernet. For others only access to the device of own station is valid except Ethernet. It must be '0'.
PC No
Specify the station number set in PLC side if you use Ethernet. For others it must be ‘255’.
*It is not able to access other stations.
Coil Read Block Size
The Coil Read Size is the block size of the data sent by the I/O Server Software, which is transferred per access between the I/O server software and MELSEC. The maximum is 8192.
Register Read Block Size
The Register Read Size is the block size of data sent by the I/O Server Software, which is transferred per access between the I/O Server Software and MELSEC. The maximum is 8192.
- 21 -
Update Interval
The Update Interval is how often data information is shared between the I/O Server Software and the MELSEC.
The unit is “ms”. 1000 ms. is the default and is suitable for most purposes.
The updated interval will establish every topic. If the actual communication time is faster than the Update Interval, the read will execute. If many topics are assigned to one port, the communication order will be as follows:
Ex.1) The Update Interval of the topic PLC1 and PLC2 is 100msec, but the actual communication time is greater.
In this case, the read function of PLC1 will become slow.
Ex.2) The Update Interval of the topic PLC1 and, PLC2 is 2000msec, but the actual communication time is less. In this case, it will read in the specified time.
Ex1)
PLC1 D400-463
PLC2 D0-63
PLC1 D200-263
PLC2 D0-63
PLC1 D0-63
PLC2 D0-63
Ex2)
PLC1 D400-463
PLC2 D0-63
PLC1 D200-263
PLC1 D0-63
If you want to create more than one topic, consider the communication time carefully when choosing the Update
Interval.
Simulation Mode
The Simulation Mode is which I/O Server runs without MELSEC. If you check the box ‘ON’, I/O Server doesn’t access to MELSEC and return random data. In this case, the poke data is not available.

Save Configuration file
The “Save Configuration “ dialog box will appear when configuration file doesn’t exist or new path is specified.
Fig. 4-4
Configuration File Directory
Accept the default path for the configuration file or use a different one by typing in a different path. Note there is no specific file name, just a path indicating a destination directory for the configuration files. Do not try to specify a particular file name as the I/O Server Software makes its own configuration files and does not permit the user to assign specific file names. In fact, changing the software-generated configuration files will cause an error. You should not try to alter the software-generated files in this directory manually or attempt to rename them.
Make this the default configuration file
By checking this box, you make the configuration file path in the Fig. 4-4 dialog box the default configuration.
Your WIN.INI file may be altered under the heading “EZSOCKET” with this path included as a WIN.INI default.
Files necessary to the functioning of the I/O Server Software will be stored in the specified directory. If you want to make multiple configuration files, you will first need to create a new directory using DOS or the Windows File
Manager, then specify the new directory and path in the “ Server Settings” dialog box. Once initial setup is done, only the new “EZSOCKET” file is saved in the new configuration directory, not all the ones saved first in the initial default directory. In ordinary circumstances, you need not concern yourself with such a detail.
- 25 -
4.2 Server Parameters (/Configure/ Server Settings...)
The I/O Server Software parameters are set here under the menu option at “Configure/ Server Settings...”. The default options are usually suitable for any given application. They might need to be changed, though, to fit your particular environment.
Protocol Timer Tick
The protocol timer tick specifies the delay in milliseconds between a command given in the I/O Server Software
(such as DDE POKE) and its execution. The proper value is 50 msec or more within 100 msec.
NetDDE being used
Choose this option if NetDDE is in use. If this item is selected than automatic communication will be activated, you will be unable to use manual communication.
Configuration File Directory
The configuration file path is the drive directory location of the I/O Server Software configuration files. If you relocate these files, be sure to modify this path accordingly, but it is recommended you leave these files in place once they have been created.
Start automatically as Windows NT Service
Choose this option if you want the Windows XP/2000/NT service to start automatically. Windows 95 users should ignore this option. (It must be installed InTouch7.x )
OK Save changes and close the dialog box
Cancel Cancel changes made since last completed update and close dialog box.

Comments
The device range used by the MELSEC varies according to model. Consult your particular model’s manual for possible contradictions to this chart. The I/O Server Software does not check for address validity, so be sure that if you are using more than one MELSEC unit of different model types that the two do not have device range conflicts.
Generally, it is wiser to use the highest possible device range for any given device on the MELSEC in your network or chain that belongs to the MELSEC with the smallest range for the given device. For example, if you were using an AnN model MELSEC (with a “D” device range of D0 - D1023) and another MELSEC of type AnA (with a
“D” device range of D0 - D6143), it would be good to limit the “D” device usage to the range of D0 - D1023 if you anticipate any “D” device data exchange between the two different models
- 30 -
You can access the Expanded File Register with “ER[Number of block] .[Device No.]”
For example, if you access block1 of the Expanded File Register, and the Device No. is 123, the form will be
“ER1.123”. Consecutive access is not available.
It can access to device range of AnACPU only, if you use it through MELSECNET2 Board.

5.3 Data Read / Write Operations
Device names and references to memory registers must follow a valid format. The InTouch Tagname should be free of the period (.) character, as it is reserved for another use by the InTouch software. It is recommended that the
Tagname reflect the content of the data register addressed but this is not necessary.
Example) If the device name is “D100.D”, a good Tagname would be “D100-D”.

# These special items can’t be used to bit device.
5.3.1 Internal Bit Device Reading (.number)
In the device name (bearing in mind these are 16-bit devices), the number after the (.) is the address of the bit examined in the given word device. Bits in a word device can be read only and not written to via InTouch or the
I/O Server Software.
Example) D101.2 ....... Refers to the value at bit place 2 in the 16-bit device addressed as D101. You can read this device bit by bit, with the range of 0-15 being acceptable; so, an address of D101.16 is invalid because it would be attempting to read the 17th bit in the 16-bit device addressed as D101.
5.3.2 Double Word Data Devices (.D)
A 32-bit device is referred to by placing a “D” after the (.) character when the first part of the entire address is the address of the first of the two 16-bit devices that comprise the 32-bit device you are attempting to read or write to.
Example) D101.D .......... Refers to the 32-bit value stored in D101 and D102.
If any anticipated value in a given 32-bit device is a real type number, the letter “R” is used instead of “D”.
5.3.3 Real Number Type (.R)
A 32-bit Real type device is referred to by placing a “R” after the (.) character when the first part of the entire address is the address of the first of the two 16-bit devices that comprise the 32-bit device you are attempting to read or write to.
Example) D101.R ......... Refers to the 32-bit value stored in D101 and D102 but returns the value as a type real number.
- 34 -
5.3.4 BCD Word Type (.B)
In the device name, the “B” after (.) is the address of identification, the data as BCD, and the data that is to be exchanged. If you intend to read data from PLC, you treat the data as BCD and exchange BIN. If you intend to write data, the procedure is in reverse order.
If the BCD type data is not properly converted (a value that is between Hex A-F, above 9999 or below 0), then the following error will be displayed and the value will be clamped in the quality information of that tag.
Hexadecimal A-F : Clamp 0
Above 9999:
Below 0:
Clamp as 9999
Clamp 0
5.3.5 32Bit BCD Type (.DB)
In the device name, the “DB” after (.) is the address of identification, the data as BCD, and the data that is to be exchanged. If you intend to read data from PLC, you treat the data as BCD and exchange BIN. If you intend to write data, the procedure is in reverse order.
If the BCD type data is not properly converted (a value that is between Hex A-F, above 99999999 or below 0), then the following error will be displayed and the value will be clamped in the quality information of that tag.
Hexadecimal A-F :
Above 99999999:
Clamp 0
Clamp as 99999999
Below 0: Clamp 0
5.3.6 Unsigned Integer Type (.U)
As above, using the format “<Device><x>.U<n>“ returns the value as a unsigned integer data type. (‘0’ – ‘65535’)
- 35 -
5.3.7 String Type Data (.S)
As above, using the format “<Device><x>.S<n>“ returns the value in <Device><x> up through the device at
<Device><(x+(n-1))> as a string data type. The string is by default stored in the PLC’s memory in hexadecimal format, with each 16-bit device holding two characters.
This format is an easy way to avoid confusion as to the range. Think of the argument <n> as being the total number of devices to be read, with the device <Device><x> being the first of these devices.
Example) D100.S5 ........ Refers to the values in D100 through D104. If the string “ABCDEFGHIJ” is returned after a read request, the contents of these devices are as follows:
D100: 4241
D101: 4443
42 Hex = ‘B’ ; 41 Hex = ‘A’
44 Hex = ‘D’ ; 43 Hex = ‘C’
D102: 4645
D103: 4847
D104: 4A49
46 Hex = ‘F’ ; 45 Hex = ‘E’
48 Hex = ‘H’ ; 47 Hex = ‘G’
4A Hex = ‘J’ ; 49 Hex = ‘I’
Of Interest:
Notice the logically reversed order in which the characters (as represented in hexadecimal format) are stored in each device; yet, note that the hexadecimal values for each character are read in each of the character’s 2-byte representations from left to right, in the customary fashion. Since for many applications you will not need to concern yourself with this detail (unless you write PLC programs that use such techniques as bit rotation on string data), it is nonetheless interesting to note and may be of some use to you at some point.
If you use EZSocket and the register read size is set to its maximum, 256 (see page 15), you can read a total of 256 words per address. “D100.S256” is valid, while “D100.S257” is not because 257 is out of range (i.e., 1-256 is the acceptable range of arguments for S). A string, then, of up to 512 characters is readable via a single one of the above kinds of addresses.
IMPORTANT: Be sure to set the InTouch Tagname Type to “Message” or this method of data-reading will not work with InTouch!
5.3.8 Decimal Type Data Read/Write (.A)
As above, using the format “A” after (.) after Word Device name enables the handling of the data in register as a
Decimal Type. Specify the register points after H. The register range is 1 to the point configured in Register
Read Block Size. Use this data in 16 bits.
Example) In case of D100.A3
It handles D100 to D102 as a Decimal Type. When D100=K1234, D101=K100, D102=K1 is stored, make the massage type tag whose tag name D100A and item name is D100.A3. Then 1234,100,1 is stored in D100A.
- 36 -
5.3.9 Hexadecimal Type Data Read/Write (.H)
As above, using the format “H” after (.) after Word Device name enables the handling of the data in register as a
Hexadecimal Type. Specify the register points after H. The register range is 1 to the point configured in Register
Read Block Size. Use this data in 16 bits.
Example) In case of D100.H3
It handles D100 to D102 as a Hexadecimal Type. When D100=K1234, D101=K100, D102=K1 is stored in
InTouch, make the massage type tag whose tag name D100H and item name is D100.H3. Then 04D200640001 is stored in D100H. This is useful when you use register in a batch with Visual Basic.
5.3.10 Batch Data Write (.F)
You can write values to the MELSEC using a text file (from Excel or via the POKE command in the I/O Server
Software.) from your computer’s hard/floppy disk drives with the following command
<Device><x>.F<n> where n is the number of words to be written and, <Device><x> is the write first device .
So, D0.F4 will read from a file a total of four data register values (D0 through D3) and write to the PLC. You must specify the text file name that you intend you use.(for example, “C:¥ test.csv”)
Ex) If 64 items(D125-D188) are received from the text file, then in InTouch the tag name is D125FILE and the item name is D125.F64.
In the InTouch memory it takes integer form and is represented as tag1,tag2,,,,tag64. To write from this file use the following script.
FileWriteFields("C:¥TEST.CSV", 0, "tag1", 64);
D125FILE = "C:¥TEST.CSV";
5.3.11 Communication Status (STATUS)
The “STATUS” command will return the communication status of the MELSEC vis-a-vis the I/O Server Software.
The result is communicated by either “1” or a “0”, “1” meaning communication is active and “0” meaning it is not active.
- 37 -
5.3.12 Communication Error (ERROR)
The “ERROR” command returns a more detailed report of the communication status than the “STATUS”
Command.
0: No error detected
100-355: Error code when Serial Link unit returned NAK
(Added “100” to error code corresponding NAK)
1001: Received time out error
1002: Communication port error
1004: Received header error
1005: Received data size error
*Those following are errors (in cases of I/O Server corresponding MELSEC-Q/QnA Series)
4000H-4FFFH:
7000H-7FFFH:
F000H-FFFFH:
Error that CPU detected (Refer to Q/QnACPU users manual)
Error that QJ71C24/AJ71QC24 detected (Refer to QJ71C24 manual)
Error that MELSECNET/10 detected (Refer to MELSECNET/10 manual)
5.3.13 Date Information (DATE)
The current date time of the computer which I/O Server runs on is stored in the special item “DATE”. It is formed as ”MM-DD-YYYY”
5.3.14 Time Information (TIME)
The current date time of the computer which I/O Server runs on is stored in the special item “DATE”. It is formed as ”MM-DD-YYYY”
5.3.15 Effective or Ineffective Communication
It is possible to start or stop the communication by the topic from DDE EXECUTE command with DDE client.
The following command is useful.
[ENABLE]......Starting communication (This is the condition at the time the I/O Sever Software starts.)
[DISABLE].....Stopping communication
If the processing data exist, the communication error occurs.

Software.
- 39 -
5.5 Accessing the quality information from InTouch
To access the quality state of a particular tag, first type in the tag name and add ( .Quality) after it,(see below).
There are six quality states:
Good : 0x00C0
There was no error during communication.
Clamped HIGH : 0x0056
If the word register exceeds the value of the 16-bit limit, or the BCD exceeds 9999.
Clamped LOW : 0x0055
If the word register is below the value of the 16-bit limit, or the BCD is below zero.
Cannot convert : 0x0040
The BCD includes characters that cannot be converted.
Cannot access point : 0x0005
An error was received from the PLC during communication.
Communication error : 0x0018
There is no reply from the PLC during communication.
* For further information refer to the InTouch manual.

5.6 Using the I/O Server Software with Microsoft EXCEL
When you are using the I/O Sever Software with EXCEL, specify the data with the following style in the cell.
= Application name | Topic name ! Item name
For example , if you set the Topic name to PLC1, and you want to access Data Register D0, specify the following in the cell.
= ezsocket | PLC1 ! D0
You need to use the DDE POKE command, macro function of MS-EXCEL, to specify the particular items. DDE
POKE command is as follows in MS-EXCEL
EXCEL Ver4
Chn= INITIATE ("EZSocket"," Topic name ")
= POKE (Chn," Item name ",Data_Reference)
=Terminate(Chn)
= RETURN()
EXCEL Ver5(VBA)
Chn = DDEInitiate("EZSocket", " Topic name ")
DDEPoke Chn, " Item name ", Data_Reference
Chn is the returned data by the INITIATE command.
Data _reference is the ID of the cell specified in POKE.
You must use the TERMINATE command to close channels because some applications have a limited number of channels.
You also need to make sure to use the TERMINATE command late enough so that the POKE command will run properly.
If you need to access Visual Basic, refer to DDE CLIENT included with this software. In regard to other ways to access, refer to DDESAMP.XLS included with this software.
# The DDE Request command cannot be used with Windows NT 4.0
- 41 -
5.7 Showing the contents of the I/O Server software
When the I/O Sever Software is accessing data, you can view the opening Topic name. You are also able to access the device name and range in the dialogue box.
Topic Name
Status = XX (OK : communicating NG : Cancel the communicating
The contents are the same as in the Item Status.
ErrorCode=XXXXX (Value of Item name ERROR is showed.
Simulated” is showed in case of simulation mode.
Device Name and Range
READ : Reading WRITE : Writing the Top address – the end address that is accessing
After the showing, “DUE” is showed sometimes but this is not communication error.
* If a communication error occurs, the Item Name STATUS ,ERROR changes and the error message is showed in
WWLOGGER.
* It takes sometime to be timeout, if it accesses to A-Buss Board without power on of PLC CPU or connecting cable.
*If you use MELSECNET2/10 Board, refer to the special link relay/special link register to check link status because READ of own device on board will not be error even if network goes down (breaking a wire or master station down). Refer to the MELSECNET Data Link Users manual about special link relay and special link register

Lap Time Indicator
S: 00FF001800100001
S:00FF001801000001000A
Elapse = the lap time value . The lap time shows the communication time for each topic. This value is the time interval between the processing of messages. The established Update Interval value will not exceed this time, but is nearly the same. If you create more than one topic, refer to this value when establishing the Update Interval.
When communication is inactive, this value will be indeterminate. In this case, the lap time is invalid.
