Description
Where can you find sample programs and documentation for communication between SIMATIC S5 modules and SIMATIC S7 modules by way of PROFIBUS using the free Layer 2 access of the FDL protocol.

In the sample programs below we use the SDA (Send Data with Acknowledge) service of the FDL protocol for data communication between SIMATIC S5 modules and SIMATIC S7 modules.
