TableApp.16 Special relay
Explanation
Turning this relay from OFF to ON enables
manual system switching during online program
change redundant tracking.
After the manual system switching disable status
is canceled, the system automatically turns off
SM1709.
System switching due to any of the following
conditions is executed even during online
program change redundant tracking, regardless of
the status of this relay.
•Power off, reset, hardware failure, CPU stop error
In either of the following statuses, the system
switching disable status can also be canceled by
this relay.
•Multiple-block online program change redundant
tracking execution status
•File batch online program change redundant
tracking execution status
Set whether the tracking of the following data will
be executed or not during online program change
redundant tracking.
•Device memory
(Including SM/SD that will automatically execute
tracking)
•PIDINIT information, S.PIDINIT information, SFC
information
SM1710 can be also used to set whether tracking
will be executed or not while online change of
multiple program blocks or batch of files is being
performed to ensure consistency of both systems.
This SM is also transferred form control system
CPU module to standby system CPU module by
tracking data.
