How to add a Lantronix UDS1100 Ethernet Gateway Site in PME

How to add a Lantronix UDS1100 Ethernet Gateway Site in PME

Unable to communicate to a Lantronix UDS1100 using the default Lantronix MSS 3001 port.

Product Line
ION Enterprise, SPM, PME, Lantronix

ION Enterprise, SPM, PME

Different model numbers of the Lantronix devices use different ports for communication.
The Lantronix MSS devices use port 3001 for channel 1 and 3002 for channel 2.
Lantronix UDS, CoBox, XPress, and XPort use 10001 for channel 1 and 10002 for channel 2.

When adding the Ethernet Gateway Site for the Lantronix UDS1100:
1.) Add the site in Management Conslole
a.) Select Sites
b.) Right click on the right field and select New/Ethernet Gateway Site
c.) Enter the IP address for the gateway
d.) For TCP/IP Port type 10001 (ignore the fact that this may not be available in the dropdown and just type the numbers)

2.) Login to the Lantronix Web page of the UDS1100 by entering the IP addess on the web brower, it will ask for a username/password, you can ignore it and just click on login
3.) Configure the Protocol, local Port and Port Settings to match downstream serial device. Example is given below.

4.) Return to Management Console> Sites
5.) Right click you site created above and select Connect
6.) Click Stay Connected

The site should connect to the lantronix and then show Connected in Management Console

What is the neon to fit the PDL 56SW110?

The 56LEDK1 is the neon kit to use. It includes the drill bit and any other parts needed to fit the LED. Visit for the datasheet, installation sheet and further information.

Can I monitor IO module health in an M340 application?

Yes, you can monitor the health of an IO module. Unity offers %SW160 - %SW167 for this purpose.
Each bit within the word will represent a module location along the bus. For example %SW160.3 would be
ontain the health status of rack 0, slot 3. If the bit value is "1" the module is healthy, if the bit value is "0" the
module is unhealthy. Each of the reaming %SW's in this group of 8 represent expansion backplanes.


Monitor Unity Quantum memory protect switch

%SW71 KEY_SWITCH   Position of the switches on the Quantum front panel provides the positions of the memory protection of the Quantum PLC. Updated automatically by the system.
  - %SW71.0 = 1   switch in the ‘memory protected’ position

  - %SW71.1 = 1   switch in the ‘STOP’ position
  - %SW71 2 = 1   switch in the ‘START’ position
  - %SW71.8 = 1   switch in the ‘MEM’ position
  - %SW71.9 = 1   switch in the ‘ASCII’ position
  - %SW71.10= 1  switch in the ‘RTU’ position
         -       %SW71.3 to 7 & 11 to 15 are not used.

Why do I see an impact on the cycle time when I update my M580 CPU to SV2.50 ?

Enhancements have been made in SV2.50 to enhance the reliability of the access to the internal memory (activation of the ECC : Error Correcting Code activation).

In most cases, very limited impact has been measured on the cycle time of typical applications.
The biggest impact is on some redundant M580 CPU systems (hot standby) where the cycle time may increase if your application has a very small code to execute but a big set of data to manage. (ECC feature only impacts hot standby memory transfer activity, and has very little impact on user code execution performance).

Possible workarounds are to :
- reduce the amount of exchanged data from primary to standby CPU
- disable the ECC feature using system word %SW150.
   ->To disable ECC: write the value 16#DECC to %SW150 (and power cycle the CPU (note: this value has to be written again after a cold start using the reset button).
   ->To re-enable ECC after a disable: write any value different of 16#DECC  to %SW150, perform a power cycle or push reset button.

- The status of ECC is given in %S109 : 0 = ECC activated, 1 = ECC deactivated.

Note: %SW150 is transferred from primary to stand-by PAC but the Standby PAC must also be power cycled to disable ECC. Verify that %S109 is set the same in both the Primary and Standby.

Basics :
- ECC (Error Correcting Code) corrects modern memories random access errors, but can slow down the memory access time.
- ECC feature only impacts  hot standby memory transfer activity, and has very little  impact on user code execution performance.
- ECC disable feature (%SW150, %S109) is only supported in M580 Hot Standby systems.
- Memory management optimizations have been deployed to compensate memory access time degradation.

Will the Compact NSX breaker be for sale in the USA or Canada?

Where can I buy a Compact NSX breaker?

Product Line:
Circuit Breakers

This breaker is popular overseas and there is interest in the US

There are no plans for a general release of the Compact NSX breaker line in North America, since the NSX is not UL Listed to UL489. (UL 489 is the standard commonly required in the US.) In the US, the Powerpact Circuit Breakers should be used (Powerpact breakers are UL, CSA and IEC-rated).

If an existing piece of equipment has an NSX breaker which needs replacing, we have made a few catalog numbers available for sale in the US. The list of numbers will vary based upon need. Contact your local authorized Schneider Electric distributor for assistance on your specific NSX catalog number.

For support on these breakers, Please see the following link to Global Operations where you can select other Countries:
