8.2 Data Sampling
III -70
(10) #21 PROCESS FORM (Setting range: 0 to 2)
Set the sampling process type.
0: One-shot (Stops only when buffer is full.)
1: Repeat valid (After the process ends (the buffer is full), the "TRIGGER WAIT" state
will be entered again.
2: Sampling buffer valid
(Note1) If a value other than "0" is set, #22 must also be set.
If not set, the sampling process will not end until it is forcibly ended.
(Note2) When "1" is set, the conditions for ending the sampling process must be set to "0". When
the conditions for ending is set to other than "0", sampling process will not be repeated.
(11) #22 E-CONDITION (Setting range: 0 to 4)
Set the conditions for ending the sampling process.
0: Sampling completed (buffer full)
1: Variable No.
(Sampling ends when the variable set in #23 is 0 or a value other than null)
2: PLC device (Sampling ends at the rising edge of the signal set in #24)
3: Address condition, true (Sampling ends when the #25 to #27 conditions are true)
4: Address condition, false (Sampling ends when the #25 to #27 conditions are false)
(Note 1)
Always set #25 to #27 when "3" or "4" is set. Sampling may not end if these are not set.
If the same value as #5 is set (if #5 is set to "3" and #22 to "3" or #5 to "4" and #22 to "4"),
sampling will not take place.
(Note 2) When "1" is set, the common variable uses the floating decimal point method, so if the
calculation results are used, an error will occur, and the value may not be recognized as
0.
(Note 3) For termination by variable No., sampling ending conditions are established when 0 or
blank is set from the machining program during automatic operation, or when automatic
operation is terminated by NC reset (NC reset 2 or reset & rewind). In reset state,
sampling ending conditions are established regardless of the variable data setting value.
(Note 4) Even fit the ending conditions are satisfied, the subsequent flow will differ according to
the value set in #21. Refer to the following diagram for details. (This also applies when
ending manually.)
