If programming is to take place via the serial interface of the PG/PC, the PC/PPI cable is required additionally. If the STEP 7 Micro/Win V4 programming software is used, programming can take place via the SIMATIC CP 5511 or CP 5611 (see SIMATIC NET) as well as via the MPI interface of the programming device. This increases the maximum permissible transmission rate to 187.5 kbps. \par\pard\tx708\tx1416\tx2124\tx2832\tx3540\tx4248\tx4956\tx5664\tx6372\tx7080\tx7788\tx8496\tx9204\tx9912\par }
