"Channels 1 to 8" for the Ethernet module and network module are the OS area for each module in the diagram to store the send/receive data of each data
link instruction
.
1 Access to PLC CPUs other than the QCPU and QnACPU is allowed only to stations
connected to the MELSECNET/10.
POINT
(1) The MELSECNET/H, MELSECNET/10 network No., group No., and station
No., for the Ethernet module in the data link instruction setting data, designate
the network No., group No., and station No., assigned to the Ethernet module
by the "Setting the number of MNET/10H Ethernet cards" indicated in User's
Manual (Basic).
This is so that the Ethernet network system will be considered to be the
same class as the MELSECNET/H, MELSECNET/10 network system, to
perform other station accessing processing for the QCPU.
(2) For details of the data designation method for the data link instruction, see
chapter 6.
(3) A maximum of eight instructions can be performed simultaneously, as long as
the channel number (1 to 8) designated in each instruction control data do not
overlap with each other when the access destination stations (communication
request destination station) are different.
There are no operation differences in the instruction format JP. and GP. ,
and J. and G. .
DANGER
[Precautions for data link instruction]
(1) In a system where AnUCPU coexist, never execute the following instruction from
the Q/QnACPU to other station's AnUCPU. The AnUCPU that has been executed
such instruction results in "MAIN CPU DOWN" or "WDT ERROR," and may stop
the operation.
1) SEND 2) READ 3) SREAD 4) WRITE 5) SWRITE 6) REQ
(2) When accessing for all Q/QnACPU stations on the MELSECNET/10 including
PLC CPU other than Q/QnACPU, perform the access using the group No.
designation.
