(a) Tag name
The tag name to perform the tag component test is displayed.
(b) Component name
1) Select the component name set in "Component setting" of the tag
setting.
(Refer to Section 6.3.3 for "Component setting" of the tag setting.)
2) The Component name drop-down list displays the setting No. and
component names of the Component setting.
(c) Data type

2) When the data type is Bit, set ON/OFF.
3) When the data type is String, set a character string.
1 When operation specification has been set to the target component,
carry out an inverse operation to operation specification for the setting
value and write the result to the device.
(Example) When "100" is set as the setting value for the component in
which "Single word" has been set as Data type and " 2" as
Operation specification, "100 / 2 = 50" is actually written to
the device.
Note that, an error may be produced between the setting value and the
actually written component value.
(Example) When "107" is set as the setting value for a component in
which "Single word" has been set as Data type and " 2" as
Operation specification, "107 / 2 = 54" is actually written to
the device.
The component value to be displayed on the Tag data
monitor is "54
2 When a real number is written to the target component, a rounding error
may be produced.
2 = 108".
