• Up to two motion FBs can be buffered after multiple start in one axis and an axes group. If multiple start is
executed when two FBs have already been multiple started, the error "Warning Starting over Number of
Buffering FBs" (warning code: 0D22H) occurs and waits the analysis of the multiple start FB in order until
on-going FB is completed. Even though the warning occurs each multiple start, filter setting can be set not
to detect the warning. For details on filter setting, refer to the following.
Page 522 Checking Errors and Warnings
When an error or a stop cause occurred in on-going FB, FBs which are waiting for the analysis are
interrupted.
• When the warning "Warning starting over number of buffering FBs" (warning code: 0D22H) occurs, note that
not to execute the multiple start until the on-going FB is completed. If the multiple FBs are waiting for the
analysis by the multiple start, the next buffering FB may not be in order.
• Since multiple started FBs are executed immediately when Aborting has been specified, the FBs are not
buffered. (When on-going FBs include a buffering FB, all buffering FBs are interrupted.)
• When an error or a stop cause occurred, all buffering FBs are interrupted (the output CommandAbort turns
TRUE).
