mode
For AI-518P, parameter RUN is used to define the event-handling mode when
program is running.
Abrupt actions affecting control execution of program are called event, as the
outcomes of events are always probably unpredicted, the aim of event handling is to
turn those unpredicted things into predicted results.
Run=A×1+D×8
Among which: A is used to select 5 kinds of power-cut event handling modes; D is
used to select 4 kinds of run /modify event-handling modes.
There are five handling functions for AI-518P series instrument when power
resume after power cut.
A=0,
start to run the program from step 1 unless the instrument was in “stop” state
before power cut.
A=1,
if these is deviation alarm after power resume, then stop the program, otherwise,
continue to run the program from the original break point.
A=2,
continue to run the program from the original break point..
A=3,
stop the program.
A=4,
go into HOLD state after power on. If it is in StoP state before power cut, then
keep in StoP State after power on.
Run/modify event handling
D=0,
neither PV startup nor PV preparation function. Program is executed as
run
