Action Explanation
Event Instruction Assignment
V1: Arithmetic in actions linked to supervision errors entering the state
V1 N A:=B
A:=func(B)
A:=B<operator>C
As soon as a supervision error occurs while the step is
active or a supervision error had been detected before the
step became active, the arithmetic is executed.
V1 NC A:=B
A:=func(B)
A:=B<operator>C
As soon as a supervision error occurs while the step is
active or a supervision error had been detected before the
step became active and the condition (interlock) is satisfied,
the arithmetic is executed.
V1: Arithmetic in actions linked to supervision errors leaving the state
V0 N A:=B
A:=func(B)
A:=B<operator>C
As soon as a supervision error leaves the state (is
eliminated or acknowledged), the arithmetic is executed.
A1:Arithmetic in actions linked with a message acknowledgment
A1 N A:=B
A:=func(B)
A:=B<operator>C
As soon as a message is acknowledged, the arithmetic is
executed.
A1 NC A:=B
A:=func(B)
A:=B<operator>C
As soon as a message is acknowledged and the condition
(interlock) is satisfied, the arithmetic is executed.
R1: Arithmetic in actions linked to setting a registration
R1 N A:=B
A:=func(B)
A:=B<operator>C
As soon as a registration is set, the arithmetic is executed.
R1 NC A:=B
A:=func(B)
A:=B<operator>C
As soon as a registration is set and the condition (interlock)
is satisfied, the arithmetic is executed.
