You can use the variable "OB1_PREV_CYCLE" and accumulate it on some static variable inside the FC and compare the accum. value with the time you want to reach (time in mili seconds) You will need to add a function parameter on your FC where you can pass the OB1_PREV_CYCLE variable in the FC call her...

You can try with this (maybe it works)

Connect the PC on scalance Network and put the scalance IP address on a web browser (I prefer Opera).
Login to the scalance and check if there is some diagnostic page.

Good luck

Hi, have you checked the diagnostic buffer in order to know the reason why the plc is going to STOP mode?
This is a very helpful information to understand the problem.

In AB the timers use the time value in ms. 900 means 900ms. Use the bit TIME.DN to perform an action when the timer expire.

Ii is not possible to see the pictures.
Have you tried:

Without the source project the answer is NO, you can't

Hi, you can use an OPC server to comunicate with PLC and use Excel (VBA) to read the tags and store in the excel file or you can store in a database. There are a lot of info about this. Google (DuckDuckgo is much beter) for OPC client in excel VBA and you can find some code you can use. Here you can...

Hello, another way to measure time is shown here: for TIA V11 http://support.automation.siemens.com/WW/llisapi.dll/52258130?func=ll&objId=52258131&objAction=csView&lang=en&siteid=cseus&aktprim=0&extranet=standard&viewreg=WW&load=treecontent and here for step7 v5.5 http://support.automation.siemens.c...

But do you need that accuracy? Of course in this application probably that accuracy is not necesary, I only put the code as an example of the way you can measure time using a counter and a time base. If you need more than 49 days you can use a byte and accumulate the days in that case you wil have ...

To measure the operating time of the pump, you can use one of the following code snippet: 1) To use this logic you have to activate Cycle Mark option in HWConfig ( cpu properties cycle / cycle mark) and select a byte for this (in this example we use MB0) Note that if the cycle mark is not enabled, a...

Use PLCSIM to run the plc logic and nettoplcsim to read the data with wincc

http://nettoplcsim.sourceforge.net/

You must read the doc of NetToPlcSim to use with WinCC

krneki im sorry i dont know what hapened with the code y didnt see the preview before posting. I corrected the post, you have to put in OB100 SET R M 1.0 R M 1.2 R M 1.6 R M 2.1 R M 2.2 R Q 0.1 R Q 0.2 R Q 0.3 R Q 0.4 R Q 0.5 the set put the RLO to "1" and then de R clear the bit (R M1.0 ....). If f...

Try using in OB100:

SET
R M 1.0
R M 1.2
...

it should work

there are another OB available for a different method of startup, such as OB101 and OB102, you can try using that OBs too

greetings

Hello mazdac, WinAC is a softplc so you can use it to simulate logic and connect wincc to it to read data. You can work with WinAC and WinCC running in the same pc for instance. You can download the program with simatic s7 software and go online and test. Also you can use WinCC to read plc data. Win...

Hi, there is not such FC / FB / SFC / SFB. Can i ask you why do you need do that? I once had a discussion with a coworker about this. I knew it was not useful (except to save the final values ​​of a DB after starting the machine and can be used as reference values​​). So I searched a bit online and ...
