Configuration
The following figure shows how the TX-I/O modules are connected to SIMATIC S7
(S7-200, 300 and 400) and to the higher-level management PC.

Features
On the Profinet side, Profinet BIM supports 100-MHz full duplex Ethernet
communication.
The performance (number of TX-I/O modules per Profinet BIM that can be used)
depends on the following specific conditions:
64 TX-I/O modules (max.)
Programmable TX-I/O module addressing range 1–120
It is recommended to start from 1 and increase in steps.
Maximum of 256 input bytes made up of the following data:
–
Total of all process data bytes of all input modules
–
Number of input modules
–
Number of output modules.
Maximum of 256 output bytes made up of the following data:
–
Total of (all) process data bytes of all output modules
The cyclical input and output data of a configured Profinet BIM can be calculated
using the following table. The number of input and output data bytes are added
together for each connected TXM module and each channel function.
