(b) If MX Component is uninstalled first on the OS1 side, the control DLLs and
ACT folders are deleted.
In this case, MX Component may not operate properly or cannot be
uninstalled on the OS2 side.
Install MX Component again on the OS2 side to operate MX Component
properly or uninstall it on the OS2 side.
(3) About start menu
When you have uninstalled MX Component, the item may remain in the start
menu.
In that case, restart the IBM-PC/AT compatible personal computer.
Programmable controller CPU-related instructions
(1) About transmission speed
As the transmission speed of the QCPU(Q mode), LCPU and QCPU(A mode),
you can set 9600bps, 19200bps, 38400bps, 57600bps or 11520bps.
For the QnACPU of version 9707B or later, you can set the transmission speed of
9600bps, 19200bps or 38400bps.
For the QnACPU of other versions, you can set 9600bps or 19200bps.
The transmission speeds of the ACPU (except A2USHCPU-S1), FXCPU and
motion controller CPU are fixed to 9600bps. (The A2USHCPU-S1 may be set to
19200bps.)
(2) Precautions for USB communication
Frequently disconnecting/reconnecting the USB cable or resetting or powering
ON/OFF the programmable controller CPU during communications with the
programmable controller CPU may cause a communications error which cannot
be recovered.
If it is not recovered, completely disconnect the USB cable once and then
reconnect it after 5 or more seconds have elapsed.
(If this error occurs at the initial communication after the above operation, the
function will be performed properly in and after the second communications.)
(3) About clock data of the programmable controller CPU
(a) For the ACPU (including the motion controller CPU), clock data setting may
be made only when the programmable controller CPU is in the STOP status.
For the QCPU (Q mode), LCPU, QCPU (A mode), QnACPU and FXCPU,
clock data setting may be made if the programmable controller CPU is in the
RUN status.
(b) For the A0J2HCPU, A2CCPU and A2CJCPU, setting cannot be made as
they do not have the clock function.
(c) For the ACPU, setting can be made independently of whether the clock
setting special relay "M9028" is ON or OFF. (Note that the special relay
"M9028" turns OFF after execution.)
For the QCPU (Q mode), LCPU, QCPU (A mode) and QnACPU, setting can
be made independently of whether the clock setting device "SM1028" is ON
or OFF.
(d) Among the FXCPUs, setting may be made for only the FX
1N (clock built-in),
FX
1NC (clock built-in), FX1S (clock built-in), FX2N (clock built-in), FX2NC (when
RTC cassette is fitted), FX
U (when RTC cassette is fitted), FX2C (when RTC
cassette is fitted) and FX
3G (clock built-in).
(e) Note that an error for transfer time will be produced in clock setting.
