Siemens S7-300

Hello

I have a small apllication to do with
1 CPU 312C
1 sinaut ST7 (TIM 3V IE)
I have the Step7 V5.4

My companie has forgot to order the MPI adaptator

Is anybody knows how to trnsfer something because for the moment no way by serial port and no way by the E-port of ST7 (i ve got only the MAC adress)

Thanks in advance

You need the MPI-adaptor for communication between pc and cpu. There is no other way with this cpu.

thank you we will try to order it
