Page 40: Input / Output Assembly Handshaking Breakdown
Input / Output Assembly Handshaking Breakdown ASCII to PLC The PLC monitors the Input Sequence Number for a non-zero value that doesn’t match the Input Handshake. This indicates new data is ready for processing. Upon receiving new data, the PLC reads the length of the data and processes it (up to 200 bytes). The PLC then echoes the Input Sequence Number into the Input Handshake. -
