(3) Virtual Serial Port & Serial Communication Program & FB200AS
⑴ Power Supply ON
⑵ Virtual Port Creation
⑶ Virtual Port OPEN
⑷ Power Supply OFF
• Virtual port may be disappeared by
power-supply OFF of FB200AS while
using virtual serial port created at
serial communication program.
• Even though a virtual serial port is
disappeared by power supply OFF
of FB200AS,may not see virtual
serial port disappearing at serial
communication program.
• Communication is not available
because of realistic port(Virtual
Port) disappearing even though
serial communication program is
operated normally.
• There may occur critical situation at
OS if virtual port is disappeared
under a serial communication
program operating.
• Therefore, certainly, serial port
communication should be finished
before power-supply OFF of
FB200AS.
That is, the power supply of
FB200AS should be OFF under
finishing virtual port.
