How to Set the Slave Mode
The setting of the slave mode is performed via the RSNetWorx configuration tool.
This section explains the specific setting method for achieving the system configuration introduced in the previous
section.
It is assumed that the size of the transmission data for each PLC is 32 bytes (16 words) and 128 bytes (64 words)
are shared. The link data specification of each PLC is shown in the figure 9.5.
See Chapter 8 for the basic operation method of RSNetWorx.
