Data transmission rate (bps)
1 Access is possible only within the range of an AnACPU device.
2 A multiple block batch read/write function can be used for the local station QCPU to which the Q series
C24 is mounted and the next CPU module, which will be another station, via MELSECNET/H,
MELSECNET/10.
Function
Multiple block batch read/write
This function is added to modules showing 9707B or later in the package indication and the DATE
column of the rating plate.
3 Access to other stations cannot be performed via data link system (MELSECNET(II), MELSECNET/B).
4 Transmission is only possible using the printer function.
5 When the Q series C24 is used, it is possible to read/write a maximum of 960 words (in case of QC24(N), it
is possible to read/write a maximum of 480 words.)
6 230400 bps can be used via CH1 of QJ71C24N (-R2/R4) only.
The maximum transmission speed of QJ71C24 (-R2) is 115200 bps.
