The VIM supports connecting to a limited number of IP addresses (System Specifications). However, there is no restriction to the number of DeltaV device that can point to a single IP address. This feature can be used to associate more than 16 DeltaV datasets to a single IP address. VIMNet Explorer attempts to make this configuration easier by defining a field device IP address once, and then further devices can just select the same address from the list.
When eitheror button is clicked from the Field Device dialog, the dialog in Figure 1 will appear. Only the options that apply to the device will be shown (i.e., if the parent VIM is simplex, the redundancy modes will not be shown).
These parameters are common to all IP address definitions.
This is the primary IP address of the target field device. The VIM must be able to send ICMP Echo commands, send and receive UDP messages, or open TCP connections to the specified IP address.
The VIM has the ability to send multiple messages before waiting for a response (i.e., an application-layer transmission window). See Simultaneous Messages for additional information.
This defines the Modbus protocol to use. See Modbus TCP - Messaging Options for more information.
Default = RTU TCP
This is the TCP port number to which the VIM will connect.
Default = 502
When enabled, the VIM will treat the network host with this IP address as a network bridge. The device must support multiple connections in order to use this mode. The maximum number of connections the VIM will establish is given in the Max Sessions field. See Serial Gateway Device for additional information.
Below is a list of devices known to be compatible with this feature:
Note: If this device is a bridge, but does not support multiple connections, use the Serial Bridge feature instead of this feature.
This is only used with the Gateway Device feature. This defines the maximum number of TCP connections the VIM will create when communicating with this device. Messages on each session are handled independently. See Serial Gateway Device for additional information.
This selects how the VIM will connect to the field device. These options are only available when VIM Placeholder - VIM Is Redundant is selected.
The field device has only one network card. VIM A and VIM B will both open a connection to this IP address. See Simplex Field Device for more information on how this device is handled.
This is used for a field device with two IP addresses, where the active IP address can be either of the IP addresses defined. See Redundant Field Device with Single Chassis for more information.
This is the second IP address of the field device. The way the VIM uses this address is determined by the Redundancy Mode above.
