Restrictions and Open Issues
Restriction / Issue
Pulling and plugging a module
during HSB roll switch can make
the I/O module not able to be
recognized.
Module diagnosis alarms are
not stable, especially when
multiple diagnoses appear at
same time.
When supporting PROFINET
System Redundancy, set
StartupMode to Advanced
Hot swap of ALG626 module
while Online with attached
HART device causes CEP blink
trap 1-2.
IC695ALG312 module is not
detected after hot insertion
Hot insertion of IO module may
cause loss of CEP PROFINET
connection for a few seconds

If used, IC695ALG628 must be installed in the RX3i CPU Rack. At time of publication, it is not supported by PROFINET scanners IC695PNS001 or IC695CEP001.
Refer to IPIs for IC695PNS001 or IC695CEP001 for future updates.
Description
When configuring RX3i CEP001 under PROFINET HSB redundancy, if you pull the I/O module
installed on an RX3i CEP001 while switching the current primary/backup CPU role, then plug
the I/O module back in and switch the primary/backup CPU role back, the I/O module might
be lost.
It is not suggested to pull/plug an I/O module during PROFINET HSB redundancy roll switch.
To recover, cycle power to the RX3i.
Whenever fault reporting is configured for an I/O module, and a fault occurs and is
subsequently resolved, the fault might not be reported via the PROFINET diagnosis appears /
diagnosis disappears alarm sequence. This situation is more likely to be encountered when
multiple alarms occur in rapid succession. Refer to Diagnosis Disappears alarms may be out
of sequence with Diagnosis Appears alarms below.
The RX3i CEP001 GSDML does not have the attribute Interface Submodule Item/Application
Relations/@StartupMode. The default is Legacy according to the GSDML specification. This
setting does not matter for simplex. However, for PROFINET System Redundancy the
StartupMode needs to be set to Advanced. Refer to Protocol (IEC 61158-6-10) in IO APDU
Substitutions. The SRInfoBlock required for System Redundancy is only available in
IODConnect.Req with StartupMode:=1.
Whenever the IC695ALG626 module is hot swapped while online with sixteen HART devices
attached to it, the IC695CEP001 may enter a blink trap1-2. To recover, cycle power to the
CEP001.
CEP does not detect the ALG312 module, when it is hot inserted. This can be observed in the
Profinet Controller, where "Addition of IO Module" is not reported and ALG312 module OK
LED keeps blinking.
To overcome this, CEP should be power cycled. After the power cycle CEP properly detects
ALG312 module and "Addition of IO Module" is reported with LED become solid green.
Occasionally, the RX3i CEP may disconnect for a few seconds and then automatically
reconnect when any of the below listed IO modules are hot inserted.

Description
If used specifically for HART Pass Through, the supporting RX3i PROFINET Controller
5 & (PNC001) and PROFINET Scanner (PNS001 or CEP001) must also contain HART-compatible
firmware:
IC695PNC001-AK Firmware Release 2.30
IC695PNS001-ABAH Firmware Release 2.30
IC695CEP001-AAAD Firmware Release 2.30.
