Hello,

I'm trying to set TOD from a User Webpage but I can't get it working.

I've managed to work with bits, bytes, words... TAGs, DB... but I'm not able to set TOD value.

Hope somebody can help me.

Thank you in advance.

Hello,

any idea?

thank you

Hello josepvr

Which kind of PLC do you use?

What did you try to set the Systemtime (example)?

where did you want to enter the Time you want to set to the PLC?

Hello,

I'm using S7 1200.

What i want to do is to set TOD variable (not PLC time) using URL and I don't know wich is the correct format.

For example:

192.168.0.1/awp/Test/index.html?"Set_time"=12:00:01

Thank you

Hello,

I've been reading Siemens documentation and I'm not able to find how this values are sent over http...

Any help is really appreciated.

Thank you

Hello josepvr

I do not know the solution for what you want to do but perhaps you could use a workaround like this:

Create an userdefined Webpage on the Webserver (there are many information an examples using AWP commands in the TIA Portal Help System). Show a Field with a Time Tag out of a DB and a triggertag (bool for example) for triggering the Timechange.

Then input the new time and write a True into the Trigger.

then you only have to program a little FC with sets you the Systemtime if you set a True to the Trigger Tag.

Hello Murof,

Finally I've found the solution, my problem was that i wasn't  "escaping" TOD string before sending to PLC.

Here comes working example:
192.168.0.1/awp/Test/index.html?"Set_time"=TOD%2309%3A00%3A00.000

*This can be done automatically with javascript escape() function.

Thank you.

Hello Josepvr

thank you for your feedback!
