(1) Component name (Up to 16 characters)
Enter a component name.
For characters that can be used for component names, refer to the following:
Appendix.1.2 Characters applicable to item names, component names, variable names, etc.
(2) Device
• Set a device type and an actual device number.
• Bit specification is not allowed for word devices.
• For accessible devices, refer to the following:
3.2 GOT Devices Available for the MES Interface Function
(3) Data type
Select the data type of the sampling data (device data).
Item
Single word
Double word
Real number
Bit
*1
String
*1 When [Data type] is [String], device values are processed as follows:
• When the device value is not an ASCII code or JIS code
It is replaced with "." (period: 2E
• When the device value is a model-dependent character
The character code may be converted when an action is executed.
Appendix.1.2 Characters applicable to item names, component names, variable names, etc.
• When the device value is a termination character (NULL code: 00
The character data following it are ignored. (The character string is regarded as terminated.)
(4) Character string length (2 to 32 characters)
(a) Set a character string length when [String] is selected for [Data type].
(b) When [String] is selected, data are stored as follows:
1) When the value length is shorter than the character string length
NULL codes (00
Example: "ABCD" is stored in the device of the tag component, whose character length is 8.
A B C D
41h 42h 43h 44h 00h 00h 00h 00h
2) When the value length is longer than the character string length
The values whose quantity is equal to the character string length are stored.
Example: "ABCD" is attempted to be stored in the device of the tag component, whose character length
is 2.
"AB"
(c) Odd numbers are not allowed for the character string length setting.
Set an even number for the character string length.
Handles data as single word data (16-bit Integer type).
Handles data as double word data (32-bit Integer type).
Handles data as floating point data.
Handles data as bit data (in units of bits (0/1)).
Handles data as character strings.
