Connecting Ethernet Ports Not
Configured as Ring Ports to
the MRP Ring May Inhibit
Ring-Break Detection
To ensure correct MRP ring-break detection, it is important to connect the correct
Ethernet ports of the RX3i PNS to the MRP ring. The ports connected to the ring
must be the same ports configured as MRP Ring Ports. Failure to connect the
configured ports will prevent the PNS from correctly participating in the MRP ring,
may inhibit ring-break detection, and may result in losses of IO Devices upon
ring-break events. It is recommended during system commissioning that the
physical network connections be verified with the system configuration for ring
ports in the system’s hardware configuration. Refer to section “Media
Redundancy Protocol Support” of PACSystems RX3i PROFINET Scanner
Manual, GFK-2737, for details on recommended MRP configuration.
Reset Password returns HTTP
ERROR 503, service
unavailable, after a restart.
On power-up, the PNS generates a local security certificate to use with HTTPS
communications. Until this process has been completed, attempts to enter the
secure web pages used to reset the password will fail with error 503. This can
take from 15-120 seconds.
ALG616, ALG626, & ALG628
Terminal Block Present Status
Bit
IC695ALG616-Fx, IC695ALG626-Fx, and IC695ALG628-Fx (and later hardware
revision) analog modules may not set the terminal block present status bit in their
module status after a PNS firmware update completes, even if the terminal block
is installed. Normal operation of the terminal block present status bit may be
restored by removing and reinstalling the terminal block or power cycling the
rack.
MDL660 does not show
correct firmware revision after
the PNS firmware update
IC694MDL660 may report incorrect primary and boot firmware through the
Explore PROFINET Networks dialogs in PAC Machine Edition in a PNS rack
after a firmware update of the PNS. Correct versions will be reported after the
next power cycle of the MDL660 module either through a power cycle of the
entire rack or by removing and reinstalling the MDL660 module.
PNS001-Axxx Reset or Power
Supply Fault with PSA140
These issues may occur in a PNS001-Axxx remote IO drop with two
IC695PSA140 Multifunctional 120/240 VAC, 125VDC 40W Power Supplies when
either of the power supplies is turned off and back on:
1. The PNS001-Axxx resets and does not power back on.
2. The P/S Fault LED on PSA140 that was not powered off and back on turns
on and no power is supplied to the modules in the RX3i rack.
If this issue occurs, it may be resolved by turning both power supplies off and
back on. This issue only applies to the PNS001-Axxx.
RX3i DC Power Supply Wiring
Recommendations
The negative side of the 24V input must be connected to the earth ground when
using RX3i DC power supplies. Refer to PACSystems RX3i System Manual,
GFK-2314 for additional information.
