Sirs,

I am trying to read modbus data from a Schnider Iem3150 via modbus rtu/tcp converter. I get data type float32 but i can not convert this to integer in logosoft 8.2. Im using latest logo 8.2. Any tips on this?

When Reading the same data With modbus test software Radzio i read the data fine so i know the 3150 and converter a working fine.

Regards

Hello

Check if data read from holding register is ok.Logo has problem with addressing  in modbus. If i read HR 1000 from logo realy is read register 999 in modbus  device.

Then the transfer from float to integer would not work.

Hello 4Karlsen

Sorry guys. Ixo is right. I haven't read carefully.

A cell phone answer. I'm on the road.

no logo reads two holding register and store this value to two words.

two words=32bit

this float poinervalue is convert to integer in logo.

in the picture with table from adress holding register is read from pac3200 first line read holding register 2

but in manual for pac3200 describe first data in holding register 1

modbus is adress from 0 but siemens has an adress is from 1
