1 The setting side is as follows.
• User : Data are set by the user before execution of the dedicated instruction.
• System : The execution result of the dedicated instruction is stored by the
programmable controller CPU.
2 Refer to Section 9.3 for the error code.
(1) The command is issued to the specified tag to collect data (refresh).
(2) Regardless of the "Sampling" setting in the tag setting, the tag data of the No. set
in (S) + 2 to (S) + 5 are collected.
However, the tag set to "Execute at high speed" cannot be specified.
An error will occur if the high speed sampling tag is specified.
(3) Executing the same instruction during execution of the instruction is not allowed.
(The second instruction will not be processed.)
In this case, even if an error is detected, the completion device ((D) + 0) and
completion status indication flag ((D) + 1) do not turn on.
(4) This instruction is not available for interrupt programs.
