TCP and UDP Ports used by PanelView Plus 6 and PanelView Plus 7 Terminals
Summary
TCP and UDP Ports used by PanelView Plus 6 and PanelView Plus 7 Terminals
Content
The following table is intended to be used as a reference for network administrators and lists all the TCP/UDP ports that are used by the PanelView Plus 6 and PanelView Plus 7 terminals. Some of the ports are closed by default and can be opened by the user. Some of the ports are open by default and cannot be closed by the user.
Not all varieties of PanelView Plus 6 and PanelView Plus 7 terminals contain all possible product features, so some terminals may not have every port in the list usable. Although DCOM components exist on the terminal, they are strictly local DCOM components. There are no dynamic TCP port assignments because there are no remote DCOM components on the terminal.
| Port | Type | Protocol Name | Default State | User Configurable | Description |
| 67 | UDP | DHCP/BOOTP | Closed* | Network Setting relating to DHCP or Static IP Address. Either in FactoryTalk View ME Terminal Configuration or in Control Panel | * This port is only open if the Network Address Type is set to Use DHCP and an active DHCP is occurring. After the DHCP protocol completes, this port is closed. This port is never open if the terminal has been assigned a static IP address. |
| 68 | UDP | DHCP/BOOTP | Closed* | Network Setting relating to DHCP or Static IP Address. Either in FactoryTalk View ME Terminal Configuration or in Control Panel | * This port is only open if the Network Address Type is set to Use DHCP and an active DHCP is occurring. After the DHCP protocol completes, this port is closed. This port is never open if the terminal has been assigned a static IP address. |
