Condition Start - Mitsubishi Electric MELSEC iQ-R-RD75P4 User Manual

Condition start

In Condition start, the condition judgment of the condition data specified in [Da.14] Parameter is performed for the positioning
data set in [Da.12] Start data No. If the conditions have been established, the block start data set as 1: Condition start is
executed. If the conditions have not been established, that block start data is ignored, and the block start data of the next point
will be executed.
The following shows setting examples and a control example in which Block start data and Positioning data are set as shown
in the setting examples.
