What Logic is necessary for you to establish communication with Samba SM70-J via a standard Router + DDNS to remote operator? What is the "Socket" ?......Is it the physical port on the HMI or a virtual one, and how do you activate one?(if necessary) I've programmed the PLC at the workshop and it was working from outside the country...but since its been on sight it stopped working.
Hello all, I just recently began my job programming PLCs for a custom welding manufacturer, so there will be many different types of programs to brainstorm and create. I am VERY new to programming itself let alone Visilogic and PLCs in general, no past experience aside from a few linux classes before coming into this job(unrelated just my only programming experience prior). That being said, I'm learning ladder logic and Visilogic from the ground up and was hoping a few of you gurus could point me in the right direction to make my learning process a bit smoother than it'd be with just google and I. To familiarize myself and experiment with the program I am using a Unitronics v350-35-ta24(B) with the 4.3 O/S. Attached to my PLC are a few digital inputs and outputs as well as an analog input and output. I have watched all the webinars on the website 5 times through, even the ones I don't understand. It seems there is a void in tutorials between the basic introductory buttons/timers videos and the complicated vectors, strings, etc. I have somebody nearby to tell me how to do what I want, but the resources to teach myself and learn in my own way seem to be lacking somewhat unless I am missing the right videos somewhere on the internet, though I have searched far and wide, to infinity and beyond, etc. At this point I can do the basics as far as buttons, jumps, timers are concerned, my only confusion with contacts at this point is how to incorporate inverted contacts/coils smoothly which I feel will come as I design my programs and find my pace. My purpose of this post was to collect as much research material as possible that I may not know of yet, any relevant videos or forums/posts/documents about ladder logic, programming, or specific Visilogic that would help me better understand the language I am attempting to teach myself. The software is very easy to understand and work with, as well as the videos/forums that I have found so far; and you all do a great job at responding to questions on here. If anything comes to mind that might help a toddler in the Visilogic world mature a little bit it would be greatly appreciated. At this point I am really trying to master using contacts in sequence to perform AND statements, using them "stacked"(for lack of better term) as OR statements, and trying to master my motor and PID instincts. I know this is a vague request and nothing exactly specific, but any examples of simple old code you may have from when you were learning or from simple programs you had to do, websites you refer to in order to refresh your memory or thought process, or ANYTHING informational about basic Visilogic and/or programming would be greatly appreciated. Hope you all have a great weekend, Derek Godown
NickV posted a topic in Vision & Samba PLC + HMI Controllers & VisiLogic SoftwareDear, Since a few weeks I started working with the Vision PLC 430 J T 2. I have three expansion modules (2 for analog inputs and 1 for load cells). Recently I've started writing down the logic of my final program. Until now I only have experience with the Siemens S7 with associated software. I want to create a sequence where the transition from state to state is based upon conditions. Only one transition can be true at any point and the sequence is always the same. I've always done this with flip flops which set and reset each other. Now I’m searching for the correct way to implement this into the Vision software. Can someone advise me on this? Thank you in advance! Nick Verlooy
