The parameter coordination is composed of a field coordination marker (low
byte) and a process coordination point (high byte).
It is the coordination markers' task to coordinate the execution of an instruc-
tion on the PST. It is executed only if the corresponding coordination event is
'true'; for the CL500, this means, that you must be in the process coordina-
tion point or that the field coordination marker must be set to 1; the same is
applicable to other controllers.
The command 'control central unit' in the CL500 system uses two kinds of
coordination markers:
D Process coordination marker (AKM) and
D for ZS501 and up: Field coordination marker (FKM)
The AKMs are set as follows:
D 00 System STOP status
H
D 01 System RUN status
H
D 02 I/O status
H
D 03 I/O status or STOP
H
D 04 EP
H
D 05 EP or STOP
H
D 06 OM1
H
D 07 OM1 or STOP
H
D FF No process coordination
H
The FKMs in the special marker area are determined as follows:
D SM16.0 to SM17.7: one-time FKMs
These FKMs are reset by the system after execution of the coordinated
command.
D SM18.0 to SM19.7: permanent FKMs
These FKMs are not reset by the system after execution of the coordi-
nated command.
The FKMs are coded as follows:
D SM16.0 to SM 17.7:
D SM18.0 to SM 19.7:
D No field coordination:
