We actually design the electronics and manufacture them. UART is king for the cheap stuff. I have written drivers to interface with USB to RS-232. Pain in the ass... Until you figure it out.
With micro controllers, at least for us, everything is still UART (~RS-232) or CANbus. Sometimes K-Line...
Hello Keith,
Thanks for your response. We are communicating with an electronic controller. The PLC is intended for an End of Assembly test. It simulates the application and constantly monitors feedback from the data stream. It's a proprietary system.
There is no handshaking. No RTS, etc. It's...
Hello,
I am relatively new to PLC. I'm well versed in electronics, just not so much PLCs. I was hoping you all could provide me with some direction.
We are trying to capture a long data stream via RS-232. We send a request for data byte. Then come up to 200 bytes of data (length is known ahead...
