Transfer of sequence program and use of monitor

This section explains the restriction on sequence program transfer and device monitoring through a
personal computer connected to a GOT unit while two or more GOT units are connected. (Excluding
microcomputer connection)
1) When a personal computer is connected to the last GOT unit
PLC
Even if there is an unused RS-232C connector in the last connected GOT unit, connection and use
of a personal computer are disabled for the following reasons.
a) Because the response is slow during device monitoring, this connection cannot be recommended
for practical use.
b) Because the communication time is long during program transfer or monitoring, a communication
error may occur in the software installed in the personal computer.
2) When a personal computer is connected to the F940WGOT
PLC
The F940WGOT is equipped with 2 channels of RS-232C connectors. However, if the F940WGOT is
connected to a GOT unit and a personal computer at the same time, sequence program transfer and
monitoring are disabled.
The two-port interface function is available only for either the function to connect two or more GOT
units or the program transfer/monitoring function. (Use of these two functions at the same time is not
allowed.)
