DEVICE EXPLANATION
(b) Reading
Reading by link direct device is allowed in the entire link device range of network
modules.
POINT
The CPU module can write/read data to/from only one network module on the
same network using a link direct device.
If two or more network modules are mounted on the same network, the network
module whose slot number is younger is targeted for writing/reading data to/from
the CPU module using a link direct device.
Note14
In the case where the station No.1 and No.2 network modules are mounted on the
network No.1 as shown in Figure 10.51, the station No.2 will be the target network
module.
