It worked!! Very... Very... Very tks for every one!!!

Wonder! I had no experience with this feature using unitronic. I understand the endian issue reasonably well. This is very necessary. I didn't know how to use the buffer functionality, if you can get the bit packet and treat it, then I'll try to do that. Thank you, and whether it works or not, I will tell you.

I UNDERSTAND THE RELEVANCE OF THE REQUIREMENT FOR A GOOD ELECTRICAL CONNECTION. BUT AN INTERESTING THING ANSWERS. CLP GETS READ VALUES IN THE ENTIRE FORMAT THAT EXISTS IN THIS ENERGY METER FROM THE WEG COMPANY. CLP CANNOT READ VALUES IN THE FLOAT FORMAT OF THIS SAME ENERGY METER. IS IT POSSIBLE THAT THIS IS AN ELECTRICAL WIRING PROBLEM? A TYPE OF DATA CAN BE READ. OTHER TYPE OF DATA CANNOT READ. SAME EQUIPMENT, SAME SETUP AND SAME INSTALLATION.

I agree that in the field the scenario is much more complicated ... the point is that in the field, using the unitronic clp to read registers of the entire type, exactly from the same equipment provided by the company WEG. values of whole registers I can read with the clp. values of float registers I can't read from that same weg equipment. for some reason, the clp is unable to read float values. even when the register created in the clp is of the real type.

yes... i can... the slave are configurade as the followed way: remote slave ID: 11 baud rate: 9600 Data bit: 8 Paraty: none Stop bit: 1 ------------------------------------------------------------------------------------------------------- this time i try use the adress register number 2... now i dont care this number... i need catch some value float. is it work i will chose the correct register float.

hi!! i try read every single combination. try read register 5 and after the falure i try read register 10. try using address long and try again using adress short. but not worked.

look item 12.4 input. sheet 65 i need the corrent value WEG-manual-MMW02-pt.pdf

ok then... in config we can see the parameter of the modbus rtu network in use. in config specs we can see the hardware in use. in config status we can see the data over this global network data online. *the value of the status is 3, i guess it is a problem. * the tag tensaoPeletStatus the value is -11 and some time this value is 13 - these values are some kind of error code but we cant have the intire errorcode list... in config weg address we can see some registers input avaliable and the most import,,, the type of format data FLOAT... and de clp unitronics will work with format REAL. weg tel me some thing about the format float in use... this float are in format float point IEEE 754. can this plc unitronics work with this format data? when a try cath othes values for test only... is the registers are format int, every gone well. but when a try change for other values ( float) i cath this error code.

hi every one. i try put one more device in my modbus rtu network. this device can communicate very well with my pc over one serial port 485. but if i put this device on the last slot of my net work, he canot work... the list with the status code in help file have explanation until the value -7. but i have the status value -11 or some time -12. please help me find tis problem
