    Hi,

    i had a play around with it and managed to work out how to convert between the 2. like you said, its just the first bit of the first line once you open it as a text file ;)
    we had the original file and the information designer demo would open it and allow changes, but could send any changes :(

    my only gripe was that i didnt want to pay for a piece of software for a single screen that is on an ageing bit of plant.
    we have e-designer and was hoping i could convert, make the change and then upload via e-designer, but alas!

    thanks for the mail message. will see how i get on :)

     

    regards
    Duncan

    i have an E-designer project which i would like up upload to the equivalent beijer HMI.

    the beijer screen is an Exter T150

     

    has anyone tried this? will it work?

    i dont really want to purchase the information designer software as we only have 1 beijer screen in the factory and it is on an oldish bit of kit. alternatively, replacing it with an E series isn't cost effective.

     

    any advice would be appreciated.

    So the moral of the story is, I should slap the programmer who wrote this bit of code! It is a relatively newly installed  piece of plant and I got complaints of counters resetting when we had any power outages.

    Thanks for clearing that up

    cant seem to find much info on this?

    i know a lot of the SD registers are for system related functions, but i believe there are some user settable ones?

    we have a piece of software using SD270 to store a totaliser figure. this is then copied to D270. is there any reason for doing it this way? are SD registers retentive when the power is cycled?

    could someone please explain?

     

    thanks

    the error is due to interference. an invalid character is causing the error. We have replaced the cable and run it a different route and this made no difference.

     

    i didnt know if there is a way to account for invalid characters in the code to stop the issue from happening?

    i have a re-occuring operational error which is bringing on the error LED on the CPU.

    i have attached the section of code that is causing the issue. every now and then, we get an invalid ASCII character which causes an error in the conversion.

    does anyone have any ideas on how i can error check the ASCII code to account for the erroneous figures that come through?

    we have tried replacing the cable and made off the screen at one end to try and stop any interference, but this made next to no difference.

     

    many thanks

    it has been a little while since I have done any real E series terminal work, but one of our systems has a set number of recipes available 1-9 I think. you set the values on one page for all the different amounts and then you just select the recipe number you wish to use and load it to use those values in the process. hope that makes sense?

    have been trying to get communication between 2 PLCs to transfer a data register. we have a Q01U with a QJ71E71-100 and I want to send a single data register to a Q02(H) with a QJ71E71-100 I have managed to get things working in a really basic program, the data is transferred ok. the issue I have is when I get a fault. I am not sure how to deal with it as it brings up a comm fault on the card and it doesn't appear very simple to restart the communications. the only way I can clear it is to stop writing to the send/receive buffer. close the connection. reset the comm error and then open the connection and restart the send/receive. even when I do this manually it isn't 100% and doesn't always work first time. please see attached of both programs. I just need a way to account for any faults with the connection. can anyone help me out? thankyou

    our company laptop is the other way round. the inbuilt serial port is spot on, but the usb to serialport adapter is iffy. I would try and download the free xpmode virtual machine and give that a go. do you have any random powersave settings that put communications ports to sleep or something strange like that? any programs running in the background that are interfering?

    J Ross is correct. you didn't need to use the extra relays if you use the PC terminal to the output card. if you start using random 24v supplies you wont do the drive any good. there is no problem with the way you have done it. some of our equipment is wired like that as we have used existing prewired output cards which are often 110vac. whether you use sink or source logic, the rules are the same.

    either use source or sink logic, set the jumper correctly, then use the PLC to drive relays for whatever you want the vsd to do. (PC) is the 24v common terminal. if you used a relay output card on your plc you could drive all the outputs from that, using the PC terminal as your 24v supply to the relays on the card. for a simple stop start 3 speed setup using source logic you need to have a switch between 'pc' and the speed you require ('rh', 'rm, 'rl). you will also need to either link 'pc' and 'stf' or have this switchable too if you are running both directions. if you connect an analogue output from your plc to terminals 4+5 you can use that as a variable speed control. hopefully that makes some sense?

    even if D12 was being written to elsewhere it wouldn't effect D11. however, D11 could be written to elsewhere perhaps? I have just compared your program to a working one and the digital inputs on that card are the same. the code to retrieve the analogue value looks the same, other than we use K11 instead of H0B. im not sure what else to suggest. im sure you have done this already, but have you done a plc reset since fitting and setting up the card? have you set up the card correctly in the plc parameters?

    may seem stupid but have you tried just double clicking the file to open it rather than trying to open it within gxworks? I have had a similar problem where it wouldn't see the file in gxworks, but would open it up ok if I just double clicked the file from the desktop.
