5.7.2Setting the master for I/O scanning
Entering the IP address of a master reserves I/O scanning for this master. This means that no other master on the network can perform I/O scanning.
WARNING
UNINTENDED EQUIPMENT OPERATION DUE TO UNLIMITED ACCESS
If the IP addresses are not set correctly, any network device may control the system or access by the master may be blocked.
•Verify that you have set the correct master IP address.
Failure to follow these instructions can result in death, serious injury or equipment damage.
The IP address of the master for I/O scanning is set by means of the parameters EthIPmaster1 ... EthIPmaster4.
▶Set the IP address of the master for I/O scanning with the parame- ters EthIPmaster1 ... EthIPmaster4.
