Programmable controller that can be mounted
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 CC-Link IE Controller
Network, CC-Link IE Field Network, 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.
7 Accessible to link direct device LW10000 or higher.
8 Accessible to extended data register D65536 or higher and extended link register W10000 or higher.
9 Available for only the CH2 side of the QJ71C24N(-R4).
