use only 32 byte 

or a device which can perform more data

is unclear which devices you use and from which the message come

also the error message is shorted from you 

Hi,

as the message contains ET200SP, I assume a BA (Basic) IM is used.
The Basic IM only supports up to 32 Byte.

As already mentioned:
Reduce the amount of configured input/output data or use another IM, for example a ST (standard)

What are the differences between the Basic (BA), Standard (ST), High Feature (HF) and High Speed (HS) modules of the ET 200SP and ET 200MP?
