The table below lists the functions that have been added or changed in the Q series
C24 of function version B.
POINT
(1) The added/changed functions shown in this section includes the functions
added in the first products of function version B or later.
For the function version, serial No., and software version of the Q series C24
and related products (CPU module, GX Developer, and GX Configurator-SC)
that can use the added/changed functions, refer to Section 2.8.
(2) See Appendix 1.1 concerning a comparison of functions in the different Q
series C24 function versions.
QJ71C24N QJ71C24
(-R2/R4) (-R2)
This function allows access to the programmable controller from a PC with
1 2
GX Developer and a GOT connected to two different interfaces of the Q
series C24 at the same time.
This function allows the control of the on or off state of the RS(RTS) and
ER(DTR) signals with the programmable controller program.
This function allows data communication with an external device at a
transmission speed of 230,400 bps.
This function allows data communication with an external device at a
transmission speed of 50 bps.
This function allows clearing reception data using the CSET instruction
during data communication using the non procedure protocol.
It is possible to clear the data even when data is being transmitted.
This function clears the programmable controller CPU information of the Q
series C24. (The programmable controller CPU information is information
about the access target CPU type used in MC protocol communications.)
When the programmable controller CPU monitoring function is active, this
function sends the monitoring information of the programmable controller
CPU to the external device through the modem.
Initializes the modem automatically when Q Series C24 starts up.
After line connection from the GX Developer, access to the QCPU from the
GX Developer is made possible through line reconnection from the Q Series
C24 (callback). Transmission costs after line connection from the Q Series
C24 side are borne by the Q Series C24 side.
This function allows data communication after the external device
completes the unlock processing of the remote password set at a QCPU. It
is executed when the QCPU is accessed from a remote location using the
modem function of the Q series C24 in the following forms of data
communication:
• Communication using the MC protocol
• Communication using GX Developer
This function allows messages to be received in the non reception protocol
by time-out in non reception monitoring time (timer 0) if the received
complete code and received data count have been not determined.
This function allows the designation of the available capacity of the OS area
that notifies the data reception failure at the time of transmission control
(DTR/DSR signal control and DC code control).
1 GX Developer cannot be connected to CH2 on the QJ71C24N and the QJ71C24N-R4.
2 GX Developer cannot be connected to CH2 on the QJ71C24.
