I tested with mtester and it worked, gave no communication errors, data traces ok, but when I test with mango, still the same problem.!

Hi,

Yes, I can read and write data from SCADA. To solve the problem, I tried to change my memory addresses, one after the other(because they were two and two, that is, for example:% M0052,% M0054,% M0056 etc,) thus: %M0052,% M0053,% M0054, etc but continues giving the same mistake now with another value, being able to read two addresses clp without following message appears:

Célula': Exception from modbus master: CRC mismatch: given=256, calc=28752 ,

Inactive time: 16:39:38 - Returned to normal

OBS: EVERY SECOND RETORNED TO NORMAL.

Recalling the previous message: 'Cell': Exception of modbus master: CRC mismatch: Given = 0, calc = 28752

And although it may read the data that I need, that message goes out forever, which indicates that something is wrong and that surely something must be set wrong, considering that my experience with Holding register is rather low, which does not happen with "coil "because I know how it works!

Hi,

Can you help me know the meaning of a message in Mangoand how could I solve it.

I am reading data from a clp Altus, configured as Modbus RTU slave. I created a data source called the Cell and various datapoints using Holding register, two byte signed integer.

When I turn the first datapoint, no problems, no menssagem alarm, but when I start to enable the following datapoints (eg offset: 30, 32, 34) leaves the following urgent message:

19:05:25: 'Cell': Exception of modbus master: CRC mismatch: Given = 0, calc = 28752

Thanks

Regards,

Nicole
