Need help to commission Modbus TCP/IP

Hello.

I have a S7 400H system and CP443-1 in my project..Right now am in the middle of the commissioning. In my site we have a Schneider PLC M241 which acts as a modbus server.. i need to read data from Schneider PLC to my PLc via CP443-1. Schneider people prepared modbus mapping and their starting address is 460201(reading holding register).when i tried to access this address via our Modbus block MB_REDCL i am getting error. But the same register can be read from Modscan software.. In our MB_REDCL block information shows that i can access registers from 0-65565.. But the Schneider PLc address lies with this range and still i cannot read the data.can anyone help me out this one..

Hello..

Thanks for your respsone.. i have provided the data type as 3 and the starting register as 60201.. since I cannot enter 60201 in tte starting register parameter i have entered in Hex code as EB29..As soon as i entered like this i am getting error in the block that check with the Parameterisarion.

As per you i have to enter 60200 and even though I tried with 60201 the next register value should be readable right...i have given length as 10 and we have more registers than 10 to be read from the PLC

Hello..

Thanks for your response.. When i set the parameters in the Block i am getting Error bit set to 1 and the status code is A006.For this the block information shows that check with the Data type, start address and length .. but when I tried to access starting address as 1 i am getting done bit set as 1.but the values are 0 showing in my DB. So which means that the values are mapped into registers 460201 and not in 40001.
