This is my first attempt at analog and I am having a problem I have the input and scaling from a 4-20 ma pressure transducer working correctly. In fact, with the built in simulator everything works. When I download the program to LOGO! I received an error. It seems that my min/max block output is not connected. I can't figure out what to connect the output of the min/max block to. I am trying to enable a text block so I can read the max pressure on my TDE as I would like to see the max pressure that a hydraulic circuit build to. LOGO! 6ED1052-2MD08-0BA0 TDE LCS 8.2.1 Thanks in advance Attachment Baler Pressure Logger I.zip (71 Downloads)

That means the block output has to be connected to something else. Exceptions are digital or analog outputs or flags. - This can be done by connecting the block output to an input of another block. - This can be done by connecting the block output with a marker or output block (M or AM, Q or AQ). - With digital block outputs this can also be done by connecting to an open terminal (X).

In your programm you must (can) delete the Block B005. You have to "adjust" B001 for the rigt sensor, thats all. What is the range of your sensor?
