GPL communications. A brief description of each of these
variables is provided in Table 2.
Table 2. GPL System Variables.
Variable Name Description
GPLPxMASTER Port x is configured as a GPL Net Master Port — x is
the port number (2 through 5). This bit turns on after
loading the Regent serial ports definition.
GPLMSTRSCAN The GPL master is scanning. If the Regent is
configured as a GPL Net Master, this bit is on after the
Start Network command is performed.
GPLCONNECT The Regent is connected to GPL. Once the Connect
Network command is performed, this bit is on to
indicate the GPL Network functions are active.
GPLINTEMP The GPL input template is defined. This bit is on after
the Load Network command is performed, to indicate a
valid input template is loaded.
GPLOUTTEMP The GPL output template is defined. This bit is on after
the Load Network command is performed, to indicate a
valid output template is loaded.
GPLSCANONE First GPL scan. This bit is on after the Connect
Network command is first performed and remains on
until several GPL communications cycles have
completed successfully.
GPLDATAxx GPL Node xx has provided fresh data — xx ranges from
01 to 31. When GPL is successfully running, the
GPLDATAxx bit is on for each configured GPL node.
While the GPL is running, if a GPLDATAxx bit turns off,
it indicates that this Regent is no longer receiving fresh
data from node xx.
GPLFLTANYBUS Fault on any GPL bus. This bit turns on if any type of
fault is detected for GPL. Normally accompanied by
GPLPxFAULT bit(s).
GPLPxFAULT Port x GPL bus fault. This bit turns on if a fault is
detected for a specific communications port for GPL —
x ranges from 1 to 6, representing the communications
port number of the Regent.
GPLFLTLOCAL GPL local bus has a fault. This bit turns on when the
Regent detects a local fault using a loopback
verification test when it transmits its own GPL packets.
Normally this fault indicates a communications module
fault, or cable disconnected.
