Soon as I exit from microwin, td200 stop talking to cpu224? I set 224 address #2 td 200 address 0 and microwin adress 3 everything works fine. If I connect the old cpu224 and td200 and microwin on pc. Everything work fine on new cpu 224XP, but what is more intresting. I cleared the memory comlplete, reloaded the program still same. I have same problem with td200 and cpu224 and I have allerady checked everything. If all this settings are correct then I expect a hardware problem but in the most cases user overwrite the parameterblock or TD200 can't find the 'td' mark at the specified startaddress. Otherwise you also get the descriped error message. Please observe if you replace the TD then you have to do this also in the new TD. Go to theTD setup and select the message 'ADR. Force the TD200 to go directly to the parameterblock (not starting at VW0)

If VW 0 contains 1000 then in VW1000 you must find 'td' other wise you get the descriped error message.Дў. The TD200 loads the offset and works.Д®xmaple. If VW0does not contain 'td' then this is the offset of the parameterblock. This is the default setting in a TDif you don't change it. If it is differnet then you have two option to correct it:ДЎ.Force the TD200 to go automatically to thestart address of theparameterblock. Go to the TD200 steup and check if the specified startaddress for the parameterblock is the same. Look what is the defined startaddress for the TD200 (see picture) and look if the first address contains 'td' in a status chart). Wrong start address of the TD Parameterblock: Now check if you overwrite a address of the parameterblock in your program and correct it. If the status chart shows different values then you have localized the problem. Open the DB1 tap of the TD200 and have a look to the first part of it.Д¬reate a status chart with the same memory areas of the first part and select the same data format.Д¬ompare the values. If you overwrite one of this memory location in your user programm then the paramterblock of the TD200 is nonvalid and the TD shows 'NO PARAMETER Block'. Open the data block page for the TD200 (see picture). The parameter block it sleve contains two areas: The start address of the parameterblock you can find in the following picture of the TD wizard:

If you have configured that the TD parameterblock is at a different startaddress then the offset is stored at VW0. To connect to a S7-1200, you need a unit with a Profinet (or eventually a Profibus optional port), and Siemens has decided to produce only graphics panels in that design.This sounds to me that you overwrite/change the parameterblock (if all settings are correct).Д«asically the TD200 (be default) looks to VW0 for the mark of the TD200 parameterblock.

Same thing is now happening with the newer TD400C, a 4-line display. Sorry, the TD200 and TD200C test diaplays were designed only for the S7-200 family and are being removed from production at this time, since they were to be programmed with Microwin and the S7-200 line is discontinued.
