  1. Hi - Not trying to dredge up an old topic but this was a relevant thread I found in my search for a solution to this issue. I'm working with Samba PLC's. I have successfully set up the Remote Operator and can successfully interface with the PLC when on the same LAN, but when off network I'm not able to get in. I had my IT contractor set up port forwarding and have tried accessing using the new external IP address provided but thus far no comms when off network, IE through my cell phone's data connection. Are there other port settings that need to modified or where else should I be looking? thanks
  2. Thanks - I had overlooked that. There allot more System Bits than I was aware of, I hadn't scrolled that far into the list.
  3. Hello I have a Samba PLC application, and have for the first time connected remotely to a Unitronics PLC via Remote Operator to demonstrate the functionality. I received a request to have a status flag or icon of some sort on the HMI screen to notify the local machine operator that there was an active Remote Operator connection. I looked in the System Bits but didn't seen anything that directly addressed this; similarly didn't see anything in the help files unless I'm just looking in the wrong spot because I don't know what to call it. thank you, Jeff
  4. This may not be exactly what you are looking for but for when I install HMI's outdoors we always protect them with a UV / Glare sheild such as these: https://shadeaide.com/ They keep the sun off and block the UV, which really kills outdoor HMI's after a few years of direct sun. They also shield the unit from harsh wind / rain / ice etc. Jeff
  5. Yes - Joe & Flex have both helped me in the past, and I should do better in acknowledging them with follow -ups here. I'm trying to learn PLC programming on simultaneously on 3 different platforms, but Unitronics has certainly been the easiest; and I've been able to apply concepts learned here into machines from other mfg. thanks guys ! Jeff
  6. Thanks here also ! So far I've been managing but I have had instances where I wanted a larger font.
  7. Thanks to all. I will certainly read into Data Tables, I can certainly see use for this on other applications, this one not so much. If the implementation of what I have written so far does not go smoothly I'll probably go that route. Jeff
  8. Thanks Joe, I do appreciate the response. I've already got a fair amount of code written with the Load Indirect, I'll probably see if I can make this work. With allot of this stuff ( PLC work in general ) I have an idea of what I need the outcome to be but I dont know what tools within the software to select to make it happen. Will post back either way. Jeff
  9. Hello I've got a new twist to an older project. I have a sampling system that I'm looking to automate so that instead of sampling A & B sides on a switch-over process, it will sample an entire batch of samples; one at a time in sequence. The user will select how many samples they will need to run at the start of the routine. The sample results will be displayed on the HMI as Red / Green radio buttons, one for each sample station; on a final results page at the end of the batch. I may have as many as 30 sample stations on the system active in the batch, and I didn't want to have to run through sets of sampling routine, rather have the same sample loop repeat itself until the sample counter clicked off. I was thinking that the Load Indirect (MI) would enable me to load the results from each test into a new MI location. A snip of code is attached. MI-15 will be my Go/No Go sample results integer, that value will be loaded into a MI location assigned by the STI dialog box in Rung 27. Am I on the right track &/or is there a better way to do this? thanks, Jeff
  10. Using a Samba 7 PLC, SM70-J-RA22, with the snap in Ethernet module installed. Unable to establish communication with the unit. Have verified the IP address, Subnet Mask & Gateway assigned is the same in both the communication setup FB's as well as the remote PC's communication window. Below is the lines of ladder logic that initialize the Ethernet module, let me know if you see something obvious here. IT is not my specialty, so this is a bit more challenging for me... everyday is a learning experience Thanks ! Jeff
  11. Hi Guys, Just wanted to follow up with a note of thanks for pointing me down the road of the "State Machine". It took me a little while to get this resolved as it was a fundamental change in how the program works and not just a set of pointers to drive the HMI. Once I got it, its great. My program is functional. Its a bit big to load the file here but a snapshot of my implemented code using the function blocks to drive the decision making logic. Thanks again, Jeff
  12. Working on that today. Part of my problem is I've got too many things going on and I wear many hats here. I get sidelined with field repairs on a constant basis and then it takes me time to get my head back into the groove of this. I don't do programming full time. Let me play with what I've got in my head and I'll post an update at the end of the day. Again I do appreciate your help.
  13. Thanks for your speedy reply. Tommorow I'll have to delve into this and play around with the comparison functions and perhaps some conditional math to make it work. Cant do anything now, all my computers at home are Mac...I only use windows for work.
  14. Hello Gentlemen, thank you for your pointers thus far. I've been sidelined with other work and now I'm needing to return to this project. I reviewed the state machine example, Thank you @Flex727 for the Link, I could never have found it without that. I can more or less follow the logic of the comparison blocks but I'm trying to wrap my head around how I apply that to what I'm trying to do. One particular question: In many of the Comparison "Equals" blocks it is a Comparison between "A" and "B". The A parameter will be some MI value, and the B parameter will be a (D# x) where the x is some numeric value. I saw some at 10 and some at 20. What is meant by the D# ? Joe - you mentioned tying the step pointer to the text display, I guess I need to see how to set up this Step Pointer. (Walk before you run, Jeff) I took the code I have written thus far and stripped it of company information. Posting it here for you to review if you are so inclined. As I mentioned before, this is loosely based on an application written for a different PLC package but we were not using an HMI, and also not using an analog input, I had a sensor with a relay out. That application was functional & successful, but I need to condense it into this package. This project involves allot of firsts for me, IE first time setting up an Analog Input of my own and first HMI job from scratch. And a new software package to make things interesting. The full system will have an A and a B side. I've only written the A side as I wanted to get it functional first and then duplicate it for the B side. thank you both
  15. No offense taken. the application is fairly involved and probably not the best to learn on but its what I need to build. I've got multiple projects going on but tomorrow I will need to carve out some time on this. thanks for your input Jeff
