Free Vcr Recommendation - Honeywell Series A User Manual

5.3

Free VCR Recommendation

We recommend that you leave at least one VCR free during configuration so that device
replacement will not require you to free a VCR first. Each Fieldbus segment requires at
least one free VCR to support reloading or replacing a device on the segment. If you
configure each segment with the maximum number of VCRs allowed, 64 per segment for
Series A FIM, you will need to free a VCR before you can complete a device
replacement on the given segment. Typically, you can free a VCR by deleting a Control
Module or device from the Monitoring tab in Control Builder. Control Builder displays a
Warning message when a segment is low on free VCRs.

role for F Fieldbus should use non-Experion interfaces

with devices in an Experion system.
Never connect non-Experion interfaces while commissioning
devices and/or loading (or reloading) Control Modules containing
Fieldbus function blocks.
Never make any parameter changes without the knowledge and
cooperation of plant/mill operations personnel.
Never use non-Experion interfaces to load or commission
devices.
Always connect non-Experion Interfaces to the network as visitor
only at one of these four addresses: 252, 253, 254, or 255.
Always connect non-Experion Interface to the network as Basic
Device Type. Never connect as Link Master Type.
You can use any spare connection terminal on the bus to connect
non-Experion interfaces; but you must make sure that the
connection is secure or it could disrupt link communications.
Carefully consider the need for using a non-Experion interface in
the field, since most of them are very SLOW in comparison to
Experion operations.
Be aware that non-Experion interfaces can use significant
bandwidth that could affect Experion performance.
Always remove non-Experion interfaces from the network when
their intended task is completed.
