[Converting two 16 bits registers to float]

Thanks Saragani, It works perfectly.

[Converting two 16 bits registers to float]

Hi,
What is the best solution for converting two 16 bits registers from modbus device to floating point in UniStream?  2x16 bit registers = 32 int to float. (IEEE754 single pr).  Is there any FB for this kind of conversion?

The device information:

0x12345678 , shall be written in two consecutive registers, where the first register is 3499. Therefor the value has to be transmitted in the following way:

                               Reg 3499, high byte  0x34
                               Reg 3499, low byte 0x12
                               Reg 3500, high byte 0x78
                               Reg 3500, low byte 0x56

I don´t believe I have to do this manually with calculation  according to standard IEEE 754. If anybody know any method, it will be appreciated.

Hi

I Have a trouble connecting to secomea too. I think there is not so many people using unistream so there are many questions that never get answered. I will follow this thread if anybody know anything about this problem ---- (secomea to unistream).

Tanks for fast response

 

It works as you said but it´s not very good to have to to do that in a running system.

 

Is it possible to boot the PLC before starting the download ("exit to boot" or "exit to factory boot" on screen)  and if yes, what is the difference between these to options.

 

Best regards

Does anybody know why this is showing up?.  This is the new trend after I got the latest version of Vicilogic (9.8.31).

 

Best regards.
