8. 3. Reserving control

It is strongly recommended that control should be reserved for a single master device.

If control were not to be reserved for a master device (for example a PLC):

•Any other Modbus TCP Ethernet client could send unwanted commands.

•Other clients could use the 8 available TCP connections and prevent the master from having control.

UNINTENDED EQUIPMENT OPERATION

DANGER

Ensure that a valid address for the IP master device has been specified.

Failure to follow this instruction will result in death, serious injury, or equipment damage.

Use the [IP Master] (IPP) menu option to configure a network master device. If a valid IP address for a master device is not specified using this option, other Ethernet clients can saturate the TCP connections or send incorrect commands leading to unintended operation.

To configure this reservation, enter an IP address other than [0.0.0.0] (0) (0) (0) (0) in the [1.9 COMMUNICATION] (COM-)menu, [ETHERNET] (EtH-)submenu, [IP Master] submenu.

•If control has been reserved:

Only the control word (CMd) written by the master with control will be accepted via IO Scanning or via Modbus TCP messaging. 2 TCP connections are reserved for this device. In this way, you avoid other TCP clients using all the available connections

(8 maximum) and the control master no longer being able to access the drive Modbus TCP server.

Other parameters written from other IP addresses are accepted (for example, adjustments or writing a setpoint). When control has been reserved and another device attempts to write the control word (CMd):

-via IO Scanning: The Modbus TCP connection for this client is immediately reinitialized.

-via Modbus TCP messaging: Control is denied.

•If control has not been reserved ([IP Master] = [0.0.0.0] (0) (0) (0) (0)), control can come from any IP address.

8. 4. Configuring IO Scanning

Refer to the “IO Scanning Service” section.

The drive IO Scanning service can be enabled or disabled in the [1.9 - COMMUNICATION] (COM-)menu, [ETHERNET] (EtH-)submenu via parameter [IO Scan.activ.] (IOSA).

It is not possible to modify the assignment of the IO Scanning periodic variables using the display terminal (integrated or graphic).

To configure IO Scanning, use the standard web server or the PowerSuite software workshop.
