Before the communication between the CC-Link master and the CC-Link slave (IC2 controller) is possible, the handshake process needs to take place. Without it no data from the master will be transmitted to station. The procedure has 3 steps:
1. If the network parameter are correct, the slave station will set the bit "Initial data processing request flag".
2. Upon receiving thi bit, the master answers to the request with the bit "Initial data processing complete flag".
3. Finally, the station (slave) sets the bit "Remote READY". That means the slave is in the normal operation mode.
