Claudio,
Enron Modbus has a special 4x registers from 45001 to 45999,
used as 32bit integers. I think you can do a little trick reading
special registers with a MCIN block an use the packin value connected
to other block (AIN) to scale the value.
I=B4m not sure but I think Enron uses functions 15 and 16 to read.
Check this an enable the MULTWR parameter on the ECB block.

Hi,
Do some of you have some experience communicating a Modicon
Integrator 30 with a RTU using Daniel/Enron Modbus??
Is necessary a protocol converter?
Thanks
Regards
