Does this open up security hole to the chassis?<br>
Perhaps different Ethernet modules should be used. <br>

test<br>
<br>
Hello, <br>
<br>
Yesterday, test was performed and results were the
expected. <br>
Standalone PLC test station configured back to its
previous configuration to allow Mike continue with his
test. <br>
<br>
Based in the discussion with Steve, two Controlnet modules
will be swapped by two Ethernet modules in the "Q1" and
"HX" PLC chassis; so in preparation for this test it will
be required the following: <br>
<br>
<br>
1. New IP address assignment for two Ethernet modules
in Hall C subnet. <br>
2. Identify Ethernet switch and ports available in
Hall C to connect two Ethernet modules - Steve will
contact Brad Sawatzky to identify switch. <br>
3. Run Ethernet cables from the switch to the modules
respectively. <br>
4. Create a new SHMS PLC program, new program will
include only the Ethernet module modifications and will
keep all I/O module configurations/values as previously
used by Controlnet - In progress by DSG. <br>
<br>
For item #1: Steve/Mike can you decide and let us know
which of the available Ethernet modules will be used? So
then we can get the MAC address from these modules and
assign the IP address. <br>
<br>
Best Regards, <br>
Pablo <br>

Hi, <br>
Sounds Good. <br>
I would like to look over the setup and test. Lets shoot
for 1:30pm today in ted 1544. <br>
<br>
Did the PLC down time include time to re-schedule the PLC
on networxs? <br>

Hello Steve and Mike, <br>
<br>
<br>
<br>
From DSG's point of view the pre-test requested has been
completed. <br>
<br>
<br>
<br>
For the test three chassis were configured as follow: <br>
<br>
Chassis #1: (Master chassis which has the controller Stand
Alone PLC) <br>
<br>
Chassis #2 : Slave 1; configured with Controlnet module
for interface communication and I/O modules <br>
<br>
Chassis #3: Slave 2; configured initially with a
Controlnet module (to then be swapped by a Ethernet
module) and I/O modules. <br>
<br>
<br>
<br>
Two PLC ACD. files (PLC programs) have been created and
used for this test. The first PLC program has the all
Controlnet configurations between Master and Slaves
chassis and is simulating the actual configuration in the
SHMS PLC systems; the second PLC program contains the
combined network configurations with Slave 1 chassis using
a Controlnet module, Slave 2 with Ethernet module, this
chassis #3 is simulating the changes that needs to be
implemented. <br>
<br>
<br>
<br>
The results of the test showed that Ethernet module work
without any problem when it was used to replace the
Controlnet module. <br>
<br>
The system is able to run with a combined network
configuration (Ethernet and Controlnet modules) with no
problems. The down period (PLC off line) measured in the
test for the PLC was less than 1 min, this is the time
needed to download the new version of the PLC program
which includes the implementation of the Ethernet module
the SHMS PLC I/O chassis. So based in this test, we can
follow the previous procedure mentioned (6 steps) and
after downloading of the new version of the PLC program to
the SHMS PLC shouldn't be any error. <br>
<br>
<br>
<br>
If you want to check the test running, please let us know
and we can go over it today and be done with this check to
allow Mike continue with his test in the Standalone PLC
test station. <br>
<br>
<br>
<br>
<br>
<br>
Best Regards, <br>
<br>
Pablo <br>

Subject: [Dsg-hallc_controls] Ethernet vs Controlnet test
<br>
<br>
Hello, <br>
<br>
To test the performance of the Ethernet vs Controlnet for
the SHMS PLC systems, Amanda, Tyler and I have done the
following: <br>
<br>
<br>
1. Set up standalone PLC to mimic how the SHMS PLC
system is set up with the controller and I/O modules in
different chassis. <br>
2. Added DSG-PLC chassis to the standalone PLC system
using initially Controlnet network for a total of three
chassis (1 controller chassis, and 2 I/O chassis) <br>
3. Began development of PLC program to very test
system works <br>
<br>
Next week DSG plans to swap the Controlnet module with
Ethernet module to verify that Standalone PLC can run with
one I/O chassis using an Ethernet module and a second I/O
chassis using a Controlnet module. <br>
<br>
<br>
Best Regards, <br>
Pablo <br>
