AND stack ANS Connects the multiple instruction blocks serially. 1
OR stack ORS Connects the multiple instruction blocks in parallel. 1
Push stack PSHS Stores the operated result up to this instruction. 1
Read stack RDS
Reads the operated result stored by the PSHS
instruction.
1
Pop stack POPS Reads and clears the operated result stored by the
PSHS instruction.
1
Leading
edge
differential
DF
(DF )
Turns on the contact for only one scan when the
leading edge of the trigger is detected.
1
Trailing
edge
differential
DF/
(DF/ )
Turns on the contact for only one scan when the
trailing edge of the trigger is detected.
