• Transition control instructions (sTRn, sBLm\TRn) (Refer to  Page 99 Forced transition EXECUTE & CANCEL
instructions (s, r) [TRn/BLm\TRn].)
• Transition control instructions (rTRn, rBLm\TRn) (Refer to  Page 99 Forced transition EXECUTE & CANCEL
instructions (s, r) [TRn/BLm\TRn].)
• Block switching instruction (BRSET) (Refer to  Page 103 Block switching instruction (BRSET).)
This instruction checks, from the first sequence step of the specified block in series, whether or not the
specified transition condition number is existed.
Because of this, processing time of the instruction differs depending on the program capacity of the specified
block (number of sequence steps), a maximum of hundred and several tens ms may be taken.
In case of occurring WDT error (error code: 5001), change the WDT setting value with the PLC RAS setting in
the PLC parameter.
