In general, CommActive is set to TRUE when receiving incoming characters, independent of the protocol. It is set to FALSE
after a 40 second timeout during which no incoming characters are processed, or when the protocol is PakBus and the serial packet
protocol on the COM port specifies off line. Note, therefore, that for protocols other than PakBus that are serviced by the
SerialIO()
instruction (ModBus, DNP3, generic protocols),
CommActive
will remain
TRUE
as long as characters are received at a
rate faster than every 40 seconds. In addition, PPP will activate its COM port with a 31 minute timeout. When PPP closes, it will
cancel the timeout and set CommActive as FALSE . Further, if there is a dialing process going on, CommActive is set to TRUE .
One other event that causes ComME to be active is the GOES instruction. In conclusion, the name CommActive can be
misleading. For example, if there are no incoming characters to activate the 40-second timeout during which time CommActive is
set to
TRUE
and only outputs data, then
CommActive
is not set to
TRUE
. For protocols other than PakBus,the active
TRUE
lingers for 40 seconds after the last incoming characters are processed. For PPP, the COM port is always TRUE so long as PPP is
open.
