Tag Settings
Tag settings are used to set display groups and other

settings in a project. Therefore, even if you change the

device channel assigned to a tag, there is no need to

change display group settings or other settings that use

tags.

The tag settings are explained below.

(1) Collect (tag index)

These are unique tag numbers assigned

sequentially starting with 0001. You cannot change

the numbers. Click the boxes to specify whether to

enable data collection.

(2) Record

Click the boxes to specify whether to enable data

recording.

(3) Device

Specify the names of the devices to assign to the

tags.

(4) Channel

Specify the channels to assign to the tags. Clicking

a button displays a separate window. Select a

channel number to apply it to the sheet.

(5) Tag No. and Tag Comment

Enter aliases for the tags as tag numbers and tag

comments. Specify up to 16 characters for tag

numbers and 32 characters for tag comments.

You can select which name to display (Tag Index,

Tag No., or Tag Comment) to suit your purpose. To

select which name to display, on the

View menu,

click

Tag Display Form.

(6) Type

Specify the tag data types. Click the arrows, and

select from the following data types.

(7) Dec. Point

Specify the number of decimal places for tags. Click

the arrows to select the number of digits (0 to 5).

Select the same setting as the decimal place setting

specified on the device. Specify ANY to retrieve the

decimal place information from the device at the

start of data collection.(See below.)

Type, Dec. Point, and ANY
GA10 can continue data collection even if you

change the connected device in the middle of

data collection as long as the Type and Dec. Point

settings are the same. For example, if you set

the tag Type to SHORT and change the device

to another type in the middle of data collection

(for maintenance or other purpose), as long as

the measurement channels use the same Type

and Dec. Points settings, you can continue data

collection.

Note that the tag Type (6) and Dec. Point (7) options

include a value called ANY.

You can select ANY if you want to retrieve the

channel information from the device at the start of

data collection and use those settings to perform

data collection. However, if the data collection time

is set to PC time and the device is not connected

within 3 seconds after the start of data collection, the

channel information will not be retrieved at the start

of data collection even if ANY is specified.

In this situation, the channel information that was

retrieved from the device at the time of device

registration is used. This is not a problem as long as

the channel information at the start of data collection

is the same as the channel information that was

retrieved from the device at the time of device

registration.

Using ANY makes the data type and decimal place

settings easier. However, you cannot verify the

actual data type.
