- 40 7.8 Device Tag Setting
7.8.1 Setting items in Device Tag setting
Enter a device tag name.
Configured tags are used in [Job settings], etc.
For characters that can be used for device tag names, refer to the following:
Appendix 2.2 Characters that can be used for item names, component names,
variable names, etc. in the product
Note that using the name same as the one set in [Server service settings] is not
allowed.
(a) Normal sampling
Tag data are collected at the specified intervals.
When [Normal sampling] is selected, the tag sampling interval can be set in units
of seconds within the range from 1 to 32767.
(b) High-speed sampling (up to 96 points)
Tag data are collected at high speed at the specified intervals.
When [High-speed sampling] is selected, the tag sampling interval can be set in
units of 100 milliseconds within the range from 1 to 600 (× 100ms).
1) Precautions when selecting [High-speed sampling]
• Be sure to create a user-specified system area in the program memory of
the control CPU.
For the redundant system, be sure to create system area for the user
setting to the Redundant CPU of both systems in the same capacity.
When the control CPU is the Universal model QCPU, RCPU or C
Controller module, creation of a user-specified system area is not
required.
REMARKS
• Registration of [High-speed sampling] is limited to one tag only. (Setting
this to multiple tags is not allowed.)
• The choice of [CPU name] in [Component setting input] is fixed to the first
item in [Access target CPU settings] (Control CPU).
• Devices of tag components can be set within the total of 96 points.
(The number of the set points can be checked on the status bar of [Device
tag settings].)
(Example) When [Double word (2 points)] is set for [Data type] of all
components, up to 48 component settings can be registered.
