[Explanation]
(1) You can confirm the workpiece state read from the tracking buffer when "TrkChk", "TrkWait" command is
executed..
(2) You can omit the step to specify <Condition number>.When it is omitted, condition number will be treated as
"1."
(3) Number which you can enter to specify <Condition number> is an integer in the range of "1" to "8." Entering
anything else causes L3110 (Argument value range over) error to occur.
(4) When you execute the writing to "M_TrkChk", L3210 (This variable is write protected) error occurs.
' Tracking buffer corresponding to the condition number 1 uses number 1.
"LBFCHK".
