The CPU reserves a communication port for the HMI with the Local HMI flag set. The CPUs can support up to 8 simultaneous communication ports for Modbus clients. Once the limit is exceeded, clients will be blocked until a port is free. The Local HMI flag has special ports reserved for its use to prevent other clients from locking it out.

NOTE: All In-Gear and Near-Gear Touchscreen HMIs should have the “Local HMI” set.

To set an HMI as a local HMI

1.On the Main Menu, click the Maintenance button. The button will only be displayed if access is allowed with the current login permissions.

2.Click the Modbus Security tab.

3.Select the Local HMI check box as shown in Figure 4-5.

4.Click the OK button to save changes (or click Cancel to cancel changes).
