i'm using the PTP.
I already succes to send the data using the block,
and now i would like to send the data step by step.
1. when the plc is startup, i will send command "26 45 30 0D" to some software.
2. after that, the software will reply with "0D 0A".
3. i need to compare the byte that received from software.
4. if it same, it will send command "40 30 0D", and the software will reply it back.
5. the sequence will go on.
6. the data that send must be in 1 packet only, it should not repeat sending the data.
how can i do that..?
