Description
The QJ71DN91 master node can exchange I/O data with
each slave node (up to 63 nodes), using its own buffer
memory.
Transfer of 512 input bytes (up to 256 bytes per node) and
512 output bytes (up to 256 bytes per node) is available.
The connection type is selectable for each slave node.
The QJ71DN91 master node can read attribute data from or
write them to slave nodes, using its own buffer memory.
For further details, refer to the DeviceNet common service in
the DeviceNet Specifications (Release2.0).
Up to 240 bytes of message data can be transferred at a
time.
The QJ71DN91 slave node can exchange I/O data with the
master node, using its own buffer memory.
Transfer of 128 input bytes and 128 output bytes is
available.
The connection type is polling method.
Table 3.4 List of configuration functions
Description
The following parameters in the buffer memory can be
stored in the flash ROM inside the QJ71DN91:
• Parameters for Master Function
(Address: 01D4 to 03CF
H
• Parameters for Slave Function (Address: 060E
• Auto Communication Start Setting (Address: 0631
The parameters saved in the flash ROM are automatically
loaded to the buffer memory when power is turned on from
off or when the CPU module is reset.
This function detects slave nodes on the network, allowing
automatic configuration of master function parameters.
Two options are available: "All configuration" used for
detecting all slave nodes on the network and "Add
configuration" used for detecting the slave node(s) added to
the network.
Programming steps for setting the master function
parameters can be reduced.
