Dear all ,
i have to design SIEMENS ASI network with 70 on/off with integrated ASI module
the PLC s7-300 with DP/ASI advanced Link
i am asked about the required component in this project
ASI power suplies - ASI accessories - ASI repeaters , i need advice from expert in ASI networkto design this network
