MODBUS TCPIP more than 40064 error

[Aimin Ariff]

Hello brothers

Now I have problem in taking data, I use modscan32 to try to see values from modbus tcpip, for input registers, address 40002 until 40070, the problem is I cannot see data up to that address, it shows "modbus exception response from slave device".. But when I set to 64, it doesnt show that error and display data up until 40064, and I try again to change length to 66, which is 40066, and there u go, error again..

Same goes in my citect, before this okay when data up to 40060, now 40080 all turn #BAD.. please help me.. Thanks in advance

Hello,

Try it with our free slave simulator and if it works, it would appear the device you are using does not support the addresses.

Simply addresses that return an error do not exist in the address map of that slave
