Precautions during control
• After positioning data analysis, the system is put in an execution prohibition flag OFF waiting status. Any change made to
the positioning data in the execution prohibition flag OFF waiting status is not reflected on the positioning data. Change the
positioning data before turning ON the positioning start signal.
• The pre-reading start function is invalid if the execution prohibition flag is turned OFF between when the positioning start
signal has turned ON and when positioning data analysis is completed (Ta < start time, Ta: Reference to the above figure).
• The data No. which can be executed positioning start using "[Cd.3] Positioning start No." with the pre-reading start function
are No. 1 to 600 only. Performing the pre-reading start function at the setting of No. 7000 to 7004 or 9001 to 9004 will result
in the error "Outside start No. range" (error code: 19A3H).
• Always turn ON the execution prohibition flag at the same time or before turning ON the positioning start signal. Pre-
reading may not be started if the execution prohibition flag is turned ON during Ta after the positioning start signal is turned
ON. The pre-reading start function is invalid if the execution prohibition flag is turned ON after positioning start with the
execution prohibition flag OFF. (It is made valid at the next positioning start.)
Refer to the following for the program example.
Global label, local label
Defines the global label or the local label as follows. The settings of Assign (Device/Label) are not required for the label that the
assignment device is not set because the unused internal relay and data device are automatically assigned.
