The IO area defined for an ET 200MP limits the number of IO modules per station. The
interface module supports a maximum of 512 bytes for input and output data for all I/O
modules in the station. Exceptions are 2 interface modules: IM 155-5 PN BA, which only
supports 64 bytes, and IM 155-5 DP ST with a limit of 244 bytes per station.
