 Input Size
– The input size must be at least 88 Bytes (44 Words). It must be large
enough to accommodate the status information required by the module, which is 88
Bytes (44 Words) and the total number of PROFIBUS input data values from the slaves
in the network. You can increase the size of this area using the size of each Input
module connected. The Input image starts with byte 88.
 Output Size – The output size must be at least 16 Bytes (8 Words). It must be large
enough to accommodate the command information required by the module, which is 16
bytes (8 Words), and the total number of PROFIBUS output data values to the slaves in
the network. You can increase the size of this area using the size of each Output module
connected. The Output image starts with byte 16.
