Setting the Block Start Data
Relation between various controls and block start data
Block start data must be set to perform Advanced positioning control.
The setting requirements and details of each block start data item to be set differ according to the setting of [Da.13] Special
start instruction.
The following table shows the setting items of Block start data prepared for various control systems. For details on Condition
data with which the control execution is judged, refer to Setting the Condition Data on page 316. (The settings of Block start
data in this section are assumed to be performed using an engineering tool.)
: Set either of the two setting items.
: Setting not possible
: Setting not required (The set value is ignored. Set the value within the setting range, such as the initial value.)
*1 NEXT start instruction is used in combination with Repeated start (FOR loop) and Repeated start (FOR condition). The control using
only NEXT start instruction will not be performed.
*2 If End is set for the repeated start, the operation that is the same as the one of the block start (normal start) will be performed.
Setting Block start data using an engineering tool is recommended. To perform the setting using programs,
many programs and devices are required. The execution becomes complicated, and the scan times will
increase.
