Partner (Controller) Compatibility - Honeywell Experion C300 User Manual

installed on a non-redundant IOTA cannot be configured as redundant. A status bit
(RDNCAPABILITY parameter) indicates whether a Series C FIM module is installed in
a non-redundant or redundant IOTA.
Redundant IOTA
Redundant Series C FIM modules are installed on a redundant Series C FIM IOTA. A
redundant Series C FIM IOTA contains only one set of switches in which to set the
Device Index. The Device Index switches on a redundant Series C FIM IOTA must be
set to an odd number. This will assign the odd number Device Index to the Series C FIM
module installed in the upper connector and an even Device Index (primary Device Index
plus 1) to the secondary Series C FIM module. Note that Device Indexes for the Primary
and secondary Series C FIM blocks must be configured accordingly.
A Series C FIM module installed in the upper connector of a redundant IOTA can be
configured as non-redundant, which allows for future reconfiguration to add redundancy.
However, a Series C FIM module installed in the lower connector of a redundant IOTA
cannot be configured as non-redundant.
A redundant Series C FIM IOTA shares a single connection to its H1 segments. It is not
valid to configure two non-redundant Series C FIM modules on the same redundant
IOTA.
See the Series C Fieldbus Interface Module User's Guide for details on Series C FIM
configuration.

Partner (controller) compatibility

Controller redundancy is only possible when the primary controller has a compatible
secondary partner. Once the redundancy private path cable is connected to a running
partner, the primary controller periodically sends a partner compatibility message that
contains information necessary to perform the compatibility check, and the secondary
responds with its own compatibility message. Each module compares local information
against the supplied remote values to determine whether the partner module is
compatible or incompatible. If all of the compatibility criteria are satisfied, then the
partner module is compatible. Otherwise, if any of the compatibility criteria are not met,
then the partner module is incompatible and synchronization is not permitted. The
following criteria are compared:
1. Factory data, such as: Vendor ID, Product Type, and Product Code must be identical
to ensure same platform hardware.
2. Firmware Type must be identical ensure same platform firmware. Some firmware
personalities that differ in functionality share a common hardware platform (for
