The /sio parameter stands for “suppress initial outputs.” The parameter applies only for interfaces that support outputs. If the /sioparameter is not specified, the interface will behave in the following manner.
When the interface is started, the interface determines the current Snapshot value of each output tag. Next, the interface writes this value to each output tag. In addition, whenever an individual output tag is edited while the interface is running, the interface will write the current Snapshot value to the edited output tag.
This behavior is suppressed if the /sio parameter is specified on the command line. That is, outputs will not be written when the interface starts or when an output tag is edited. In other words, when the /sio parameter is specified, outputs will only be written when they are explicitly triggered.
/stopstat_or_/stopstat=__digstate_Default:_/stopstat=_”Intf_Shut”'>/stopstat or
/stopstat=
digstate Default:
/stopstat=
”Intf Shut” Optional
If the /stopstat parameter is present on the startup command line, then the digital state Intf Shut will be written to each PI Point when the interface is stopped.
If /stopstat=digstateis present on the command line, then the digital state, digstate, will be written to each PI Point when the interface is stopped. For a PI 3 Server, digstatemust be in the system digital state table. For a PI 2 Server, where there is only one digital state table available, digstate must simply be somewhere in the table. UniInt uses the first occurrence in the table.
If neither /stopstat nor /stopstat=digstateis specified on the command line, then no digital states will be written when the interface is shut down.
