long integers - modbus

[willburg]

I've got a problem.

In the installation the Jazz t40 is modbus master with a inverter as modbus slave.

Now a want to sent a long integer to the inverter, is this possible.

The inverter gets the numbers in a low and highbyte adress .

Search "long integer" in the U90 ladder helpfile and have a play with SB82.

 

I think it will probably do what you need, that is place a long integer in two consecutive MI operands.  It looks like the drive handles "longs" the same way.  You may need to pay attention to the word order - whether the high word or low word comes first.

 

I hope this helps.
