When the Load Network command is completed, the system
variables GPLINTEMP and GPLOUTTEMP will be on,
indicating the GPL input and output templates have been
loaded.
Unload Network
The Unload Network command deletes the GPL configuration
from the Regent. This command cannot be used while the
network is active (see Connect Network below).
After using the Unload Network command, the system
variables GPLINTEMP and GPLOUTTEMP will be off,
indicating the input and output templates have been deleted.
Connect Network
The Connect Network command activates the primary
functions for GPL communications. This fully activates the
GPL for Regents with only Net Slave type ports. If the Regent
has a Net Master port the Start Network command should
also be used (see Start Network, below).
After the Connect Network command is performed, the system
variable GPLCONNECT will be on, indicating the network is
active.
While the network is active, the Regent will respond to poll
commands received from a Network Master and broadcast its
GPL output variables to the network. The Regent will also
process GPL input data broadcasted from other Regents
communicating on the GPL network.
The first time the Network is activated after it is loaded, the
system variable GPLSCANONE turns on. This system
variable remains on until several valid GPL communications
poll requests are received from a Network Master on one or
more GPL legs.
Once the network is activated for a Regent, most loading and
initialization commands from W
INTERPRET are no longer
allowed. The particular commands are listed in Table 6.
