I'm trying to use the Bertan 225 driver. However, using the driver I cannot turn on the voltage (it does not produce any errors and the code it puts out seems to match the user manual).
Does anyone have any experience with this? Or any ideas?
I can put the codes in
L00.500K
L1.0000M
OC1OE1OE2
SE1SC1
P0.05000K
And I can turn the instrument to local and it goes to 50 V (0.05 kV). Then I can put in
L00.500K
L1.0000M
OC1OE1OE2
SE1SC1
P0.10000K
And I can turn the instrument to local and it goes to 100 V (0.1 kV).

I'm working on a big optimization problem on GAMS so it's impossible for me to put the entire code here but I hope you could help me with where I am stuck at. I have 4 power nodes in my model that are connected by 2 bidirectional transmission lines (r) like this.
where r_a, r_b are the current transmission line capacities. Power can flow both directions and I'm tracking power going from A to A' and B to B' as well as from A' to A and B' to B. So there are 4 power flows (f) in 2 transmission lines (r). My decision variables are how much capacity upgrade (c(f)) I need to build in each of these lines to satisfy more power flow needs. So in GAMS, I minimized the cost of upgrading as:
investment_cost.. cap_cost =e= sum(f,c(f)*capCost(f));
here capCost(f) is the capital cost of upgrading the transmission line capacity to be able to flow 1 extra GW her hour.
My constraint: In each time period (t), the total power flow p(f,t) must be less than or equal to the existing line capacity + newly upgraded capacity:
line_cap(f,t).. old_line_cap(l)+c(f) =g= p(f,t);
However, my solution looks something like this:
fAA': 6.7 (built 6.7 GW more of capacity in line from A to A')
fA'A: 5.0 (built 5.0 GW more of capacity in line from A' to A)
fBB': 5.5 (built 5.5 GW more of capacity in line from B to B')
fB'B: 8.1 (built 8.1 GW more of capacity in line from B' to B)
But this is not right because if I upgrade line AA' by 6.7 GW, I don't need to upgrade line A'A, since they are the same line. Basically, I pay twice to upgrade the same line.
So I fix this, I'm trying to use Alias such as this:
Alias(f,ff)
line_cap(f,t).. old_line_cap(f)+c(f)+ sum((f,ff)$[line_source(f)=line_sink(ff) and line_source(ff)=line_sink(f)],c(ff)) =g= p(f,t);
But that still does not fix my problem.
I'd appreciate any help! Thank you!
If you want to stick with your 4 fs, let's call them your virtual lines (since a pair of two of these virtual lines actually form one physical lines). Now, let's introduce a new set of physical lines (fPhys) and a mapping between the virtual and the physical lines (fMap):
Set fPhys / fAA, fBB /
fMap(f, fPhys) / ("fA'A", "fAA'").fAA
("fB'B", "fBB'").fBB /;
Now, you can stick with using the set f for your flows, and use fPhys for the investment decision, like this:
investment_cost.. cap_cost =e= sum(fPhys,c(fPhys)*capCost(fPhys));
line_cap(f,t).. sum(fMap(f,fPhys), old_line_cap(fPhys)+c(fPhys)) =g= p(f,t);
I'm trying to get a BG95 to activate on hologram.
Here are my commands:
AT+QCFG="band",F,180A,180A OK
AT+QCFG="iotopmode",2 OK
AT+QCFG="nwscanseq",020301 OK
AT+QCFG="nwscanmode",0 OK
AT+QCFG="snrscan",0 OK
AT+QICSGP=1,1,"hologram","","",1 OK
AT+QIACT=1 ERROR
At first I thought it was antenna/signal related so I ran AT+CSQ and got this:
+csq: 11,99
This tells me I have a good signal I believe.
Next I tried AT+QNWINFO and get this:
+QNWINFO: "eMTC","311480","LTE BAND 13",5230
In my mind this is saying it's connected to a network.
After trying that I tried to activate again and got this:
AT+QIACT=1
ERROR
The weird thing is it activated just fine about a week ago with pure AT commands. I did try and use an Arduino library with it (WisLTEBG96TCPIP) which may have changed a setting in it. I've done a factory reset but the it still woln't activate.
Another strange thing is the hologram dashboard. Every once and a while it will show the SIM as connected, even though I can't activate.
I have tried with 2 different SIM cards any get the same activation error.
Any help would be greatly appreciated!
Verizon has cut off all non ODI products. If your hardware has not been Verizon ODI 'certified' it will no longer be allow to be connected to their network, I have 5 new pet rocks thanks to them. The solution is to purchase new modems from vendors that have been through the Verizon ODI program or switch carriers.
I had the same problem before, after a lot of maling with network operator I find out that there isn't a LTE-CAT-M1 (eMTC) network in my area, I tested in another area successfully
Also before setting AT+QCFG commands try AT+CFUN = 0
and after setting AT+QCFG commands try AT+CFUN = 1 .
before sending AT+QIACT, try 'AT+CEREG?' command several times and tell me what is the return of it
i have given the thread count = 50
rampup period =0
for 48 threaads it is getting passed , for 2 threads there is no failure captured in the selenium log files.
I am expecting concurrent login of 50 users with 0 rampup period , i am not able to find out the exact reason of failure . please suggest the fixes to handle this scenario.
Check jmeter.log file for any suspicious entries
Add View Results Tree listener to your test plan - it will allow you to inspect request and response details
50 real browsers might be too high for a single machin
as per WebDriver Sampler documentation
From experience, the number of browser (threads) that the reader creates should be limited by the following formula:
C = N + 1
where
C = Number of Cores of the host running the test
and N = Number of Browser (threads).
as per Firefox 62.0 system requirements
512MB of RAM / 2GB of RAM for the 64-bit version
So you will need a machine with 51 cores and 100 GB of RAM in order to ensure there will no be JMeter-side bottleneck. If your machine hardware specifications are lower - you will have to go for Remote Testing
In normal applescript, the script is executed down the page, and so any code in loops for every 5 seconds will only run while the loop is running - there is no way to have a single function run every few second regardless of what the script is currently doing or where it is in the script (that I know of). In cocoa-applescript, however, is there a way to run a handler every 5 seconds, at all times, no matter what it is currently doing? Here is what it should be doing in my cocoa-applescript app:
on checkInternetStrength()
do shell script "/System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport -I | grep 'agrCtlRSSI:'" -- this being the script which returns the line containing the signal strength
set SignalStrength to result
set RSSIcount to (count of characters in SignalStrength)
set SignalStrength to ((characters 18 thru RSSIcount of SignalStrength) as string) as integer -- this to turn SignalStrength into just the number and not the whole output line
set SignalStrength to (100 + SignalStrength) as integer
set SignalBar's setIntValue_(SignalStrength) -- SignalBar being the Level Indicator described below
end checkInternetStrength
Summed up, it runs the airport command to check internet connection, turns this into a number from 1 to 100 and uses this on an NSLevelIndicator (100 maximum) to show current signal strength graphically. Now, there is no point having this run once or when you hit a button - that is an option, but it would be nice if it updated itself every, say, 5 seconds with the realtime value. So is there any way to have a process which runs every 5 seconds to do this, while still enabling full functionality of the rest of the script and interface - i.e. as a background process? Comment if you need more extracts from the script.
Example
In Unity-C# scripting, the 'void Update() {code}' will run the code within it every frame while doing everything else simultaneously, so a cocoa-applescript version of this might be an answer, if anyone knows.
I Dont believe this is possible but what I had a similar problem before, what i do, I have an external applescript applicaion that is hidden the repeats the commands, the only problem is, it wont send it back to the app, you'll have to make the external applescript app do it, like
display notification, etc..., in the applescript apps "Info.plist" you can add this:
<key>LSUIElement</key>
<string>1</string>
To make the app run invisibly, but sorry i dont think you can run a handler in the app its self
I have a VW Golf 4, which is quite old and talks KWP 2000 (ISO 9141) on its CAN bus. I use a dongle powered by ELM 327, connected to the OBD-2 port of the car.
I am trying to send messages individually to each ECU. I tried to change the header of the messages:
AT SH 48 XX F1 (I hoped XX would be the ECU ID; 48 is the flag for "use physical addressing"). Any command I issue (e.g. tried 3E for "tester present") returns NO DATA (I disabled automatic timeouts and set the timeout to maximum value).
Is there a way to send messages directly to the ECU? I am not interested in the set of data provided via OBD-2, neither do I want to re-flash the ECUs. At the moment I just try to find out which ECUs are available on the bus.
Thanks!
VW works on Transport Protocol TP 2.0, hence you need to initialize with 0x200 header.
