I'm trying to communicate the Microwin Software to a S7-200 CPU 226
using two Radio Modems, one of them (Master Radio) connected to the RS-232 serial port of my PC, and the other radio (SLAVE) connected to PORT 0 of PLC through RS-232/PPI Multimaster cable. Both radios works in transparent mode.
I need to succeed this communication so that I could make remote downloads/uploads of the PLC user program. When I try this communication, the Tx/Rx leds in the PPI cable blink, but the CPU is not found. Could someone give me a tip about that?
