With PPI you can connect only one node ( i.e one TD200). See the below points for the communication port functionality of the CPU224XP * MPI Yes; as MPI slave for data exchange with MPI masters (S7-300/S7-400-CPUs, OPs, TDs, Push ButtonPanels); S7-200-internal CPU/CPU communication is possible in the MPI network with restrictions;transmission rates: 19.2/187.5 kbit/s * PPI Yes; with PPI protocol for program functions, HMI functions (TD 200, OP), S7-200-internal CPU/CPUcommunication; transmission rates 9.6/19.2/187.5 kbit/s * serial data exchange Yes; as a freely programmable interface with an interrupt option for serial data transmission withexternal units with ASCII protocol baud rates: 0.3/0.6/1.2/2.4/4.8/9.6/19.2/38.4 kbit/s; at 1.2 to 38.4kbit/s, the PC/PPI cable can be used as an RS232/RS485 converter.
