Hi there, I have to update program on a site where we already have 2x samba 43 in place, I will need to poll some modbus values and show them on the displays from 4 RS485 devices, - VSD and soft starters, these will all be on a RS485 to TCP gateway, in my complete program I have made a separate working example of what i'm trying to do, by using 2 spare sambas i have, as a master & slave combo i just wanted to know if its the best practice way of doing it when polling the 24 to 30 different values needed I am also curious about the settings to do with SB168 Link lost auto recover, do i then need to set some time values in SI 103-110 to make it work properly? Any help or advice is always appreciated! network.vlp network slave.vlp
Hello, I am a first time user for the program and so far i've been learning from using the tutorials and i'm struggling to configure a relay output connected to a solenoid. So from what i've found i believe i have assigned the solenoid to O0 and have added this to my ladder. Can anyone confirm if this is correct? essentially i need the solenoid to open when a button is pressed for 2 seconds. Thanks in advance
Hello, I have been struggling on this project for work. It is an automated assembly station. I am still very green when it comes to programming. I went through what I had tonight and tried to make it work. Would anybody be kind enough to look thru my code and give me some pointers? Maybe tell me what I am doing wrong. I haven't had any formal training so I would like advice from some pros. I have attached the subroutine. Thank you in advance. Scott AUTO MODE-1.vlx
