9-3-6. System Area PLC Handshake
PLC Ladder logic is required to enable the CC-Link communication link.
If the CC-Link communication link is not exist, the PLC side can receive the output signal from
the Expantion Unit, but the Expantion Unit side can not receive the signal output from the PLC.
The handshake is executed when the control power of the unit is turned on.
The logic must address the enable bit (Initial Data Processing Request) of which the address changes based
on the size setting used.
The last 16 bits of both the Inputs and outputs (no matter what size is configured) is the CCLINK system
setting area and this is where the link must be enabled.
