If all existinginformation in the input and output image is made available then the processdata qualifier is additionally transmitted in the opposite direction.The following table shows a list of the number of bytes for the individualmodules that are allocated in the respective process image (PA) and thetelegrams (TLG) in the direction of transmission and reception (Tx, Rx).Module 75x-4xx nAE, …Data length / [Byte] Data objectPA TLGType E A Tx Rx E INST A INST2AI 4 - 5 1 INT16 2 - -4AI 8 - 9 1 INT16 4 - -Module 75x-4xx nAE, …, EMData length / [Byte] Data objectPA TLGType E A Tx Rx Input INST Output INST2AI_EM 6 6 7 7 INT16 2 INT16 23AI_EM 12 12 13 13 UINT8,UINT8,INT16 3 UINT8,UINT8,INT16 34AI_EM 12 12 12 12 UINT8,UINT16 4 UINT8,UINT16 4
