Saia xx7 is very similar to Simatic (but it uses its own configurator for in/outs) VIPA can be programmed using standard Ethernet cable and SAIA either Ethernet or RS232 (no need to purchase MPI converter) Moreover, VIPA accepts standard (not special expensive Simatic) MMC cards (micro memory card which is a must - without it PLC will not boot)
