262. x AutoID Reference Guide Working with Multiple Input Modules The previous sections have shown how to choose 64 byte input con and 64 byte output con in configuring the data exchange modules It has been stated previously that 64 byte output con is sufficient to handle all command or acknowledgement packet You can also choose smaller input and or output modules if your application requires sending much less than 64 bytes of data and or receiving short commands such as READ n For example you can choose 32 byte input con and 8 byte output con if the master needs to receive a 32 byte packet and send a 8 byte command packet Note You should do the same in SyCon for both the master and the slave On the other hand when your application requires reading high density Data Matrices and or performing print quality verification then you will need to transfer far more than 64 bytes for each read Multiple data packets of 64 byte long will have to be sent to the master and to be acknowledged To improve the efficiency and reduce the number of acknowledgement packets you can also configure multiple input modules to arrive at a larger packet number between 64 and 244 bytes The Profibus protocol allows up to 244 bytes of data to be transferred as input or output the sum of input and output modules should not exceed 368 bytes For example you can configure multiple input modules of 64 64 64 32 and 20 bytes in the exact same order in St
