#95461 - textile machine ... Responding to: ???'s previous message |
1) I don't know other communication methode
If that's the case, I think you know too little to handle the noise problems you ARE going to have based on waht you say in 3). 2)Some stream comming from PC that receive master then master transmit some stream to slaves. Because mater have ram,lcd display and implement external intrrupt.External intruupt join external notification machnisum. That does not answer "why not I/O expansion on master?" 3) At this time i have to interface 40 small relay and in future its increase 100,300,600 relays.Because i have to implement electronic jacqured.Electronic jacqured is textile machine thats generate pattrents. Last I did textile machinery, the slaves were remote, are yours? Erik |
