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 either Add or Edit 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.
When the parent VIM is redundant, the options below are visible. These options are hidden when the parent VIM is simplex.
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 that has two IP addresses, where the primary IP address is always the active IP. See Redundant Field Device with Dual Chassis and One ENBT for more information.
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 used for a field device that has a hot-standby chassis. In this case, each chassis has two network interfaces. See Redundant Field Device with Dual Chassis and Dual ENBT for more information.
This is the IP address of the second chassis when using Dual Network Card Redundancy Switching IP. The way the VIM uses this address is determined by the Redundancy Mode above. This parameter is only enabled when Dual Network Card Redundancy Switching IP is selected. In all other cases, this value is not used. For the other two redundancy modes, the secondary IP address is calculated from the primary IP address; it is always one plus the main IP address.
