Hi! I'm new to this forum so please be patient with me. I'm trying to automate a cable cutter that uses Unitronix M90. I want it to load a certain length and quantity when I scan a barcode. Have any of you sirs connected M90's RS232 to the serial of Raspberry Pi? Is there a set of code to send to the M90 for it to be able to communicate? Sorry the machine is always running and I need data before I can try and test. -
My end goal is to send data over ethernet using the TCP/IP protocol to a raspberry pi. I already have the pi coded in python to look for a connection to its ip on a socket that I bound to it. My problem I believe is within the V570 PLC programming logic itself. I have initialized the card with ip 10.1.10.160 and my laptop with ip 10.1.10.100. Those two communicate correctly over ethernet. My pi is at ip 10.1.10.166. The pi is bound to a socket and currently waiting for something to connect to it on port 8888. I initialized socket 3 on the PLC as a Master on port 20257 and set the name to 'raspberryplc' Like I mentioned, the PLC and PC communicate correctly over ethernet. Lastly I have the TCP/IP config block which is initialized to socket 3 at ip 10.1.10.166 on port 8888. I then use SB142, 146 and 150 to check if I'm ready to attempt a connection, all still good and expected. I get a status 0 from the TCP/IP config block which signifies an all set response. I then have my TCP/IP CONNECT block set to Socket 3 to remote ip 10.1.10.166 on port 8888. At this point SB150 never goes high and I don't establish a connection. I can see something must be happening as when I stop and start the connection attempt on the PLC side, I can see the ethernet lights blinking on the raspberry pi. Thoughts? Either I'm missing something or it's correct but my raspberry pi is messed up. Thank you for any help anyone can offer.
