(2) Transition Condition
The size of 1 transition condition is 11 lines x 10 columns, and the
number of instruction steps is a maximum of 110 steps.
When there is no transition condition corresponding to a certain
transition, that transition condition is always regarded as true.
(Dummy transition)
In programming, by designating the transition on the SFC screen
and selecting the detail display mode, the monitor/edit screen for
the transition condition corresponding to that transition will appear.
In the case when the content of the transition condition is only 1
instruction of NO contact or NC contact, direct editing can be
carried out without putting up the detail unit display screen. See
the programmer (T-PDS) operation manual in a separate volume
for this operation.
The following execution control instructions cannot be used in action
programs and transition conditions.
*
Jump (JSC/JCR, JUMP/LBL)
* Master control (MCS/MCR, MCSn/MCRn)
* End (END)
* FOR - NEXT (FOR/NEXT)
The invert contact and various coil instructions cannot be used in
transition conditions
