Thanks for that :) i think i'll tackle the online mods first as they seem to be easier than going straight to installing a new card on a remote io scanner.

Nice one kaare_t, your a star!!!!!

Hi, i have to do a firmware upgrade of a e1101. i've been told (other forum post) that the firmware is on the Mitsubishi edesigner CD, the problem is that don't have access to it at the moment. But i do have edesigner on my laptop. Is there a download i can get? online. Also i need to know what mode the dip switches need to be in when upgrading the firmware. Thanks Stuart

I knew it was somewhere, thanks :)

Hi, today i connected to our Q-series plc and tried to go into monitoring mode but got this warning "no binary, POU, DUT found" also when i verified the project i got a similar message. I definitely know there's code on the plc as it runs. Can anyone tell me why this is? As im trying to go online. Stu

Hi, thanks for the response. I built the code with no errors, then i did a rebuild all. The compile was cancelled due to number of warnings, this code is current. So not sure whats going on Warning in NW32: C9131 The bit output function EQ_E is changed in every case because the project specific option to SET/RST is not set.

Hi, i have a Q series PLC and an E1000 HMI. The HMI connects to the PLC via the front connection on the PLC. What i'm wanting to do is connect to the PLC via the HMI using ethernet? So i can use the HMI and monitor whats happening. Also i'm using GX IEC developer as it a older system. Stu

Thanks for the reply

Thanks, reason why i ask is i use IEC 61131-3 standard and they only have one output when using functions. Stu

Hi, very simple question. When creating a function (FC) you declare the inputs you want to have and you have only one output. Is that correct? Stu

Hi, can anyone explain how an encoder is read into a PLC. My understanding is it use pulses? is that correct? How does that work? Thanks Stuart

Thank You

Hi, Thanks for the reply. I am correct in saying that depending on what PLC is used, that the way the PLC interprets encoder is different? and the encoder outputs are different too? Stu

Hi, i'm using Mitsubishi, Siemens and beckhoff. What you said about upload is what i thought, but like you say Upload is vendor specific. It can get confusing sometimes when trying to learn different vendor PLC's. Stu

Hi, my understanding of an upload is to get a copy of the code on the PLC. But what else is it used for? What can you do and not do with it. Stu

Nice one, thank you very much. Sometimes the syntax can be very confusing

Hi, i want to call a function block from within a function block. What I want to know is, what the syntax should look like and how you can use the output from the FB you are calling. Stu *in title it should be "call function block in a function block".

Hi, no you have not miss understood the question. I've forgot to put for "Structured Text", sorry. Stu

Hi, as it is an older system. Tibbo will be used instead of purchasing a card. I had a chat with a contractor we use and he said he always had trouble connecting to the E1070. He says that its due to always never knowing which ip address to use when setting up the E1070 through e designer. The last time he tried to connect to the E1070, he had to reset the E1070 back to factory default to get the ethernet connection to work. So this might be why i'm having trouble connecting. I've connected to lots of other systems e.g. Beckhoff, Siemens. Just never had so much trouble connecting via ethernet to this system. Then again it might be just as easy to connect directly to the PLC as you can't use the HMI in pass through mode anyway. Thanks for help, much appreciated.

Hi, shortly i'm going to start using Mitsubishin GX IEC. I'm looking for some advice, tips etc on how to get the most out of using GX IEC. I've used Beckhoff Twincat IEC using structured text language for about a year, but i'll be using ladder logic instead of structured text for GX IEC. Is there any good examples, tutorials to speed up my learning of this?? Stu

Hi, Thanks for the response. I think i may have confused people in what i want, the second part of your answer is exactly what i'm doing. I will be programming and monitoring the PLC through the HMI in transparent mode or pass through mode. What i'm strugging with is why i can't establish comms with the HMI through ethernet. Even though the ip addresses of the PC and HMI are on the same domain. Thanks for your help, its much appreciated

It seems i need a piece of software called TIBBO as well.

Hi, Thanks already done this. Still having communication issue, going to check cross over cable and laptop to see if there is an issue there.

HMI panel set-up, just having trouble establishing access through the ethernet. Keeps displaying no network access, will the ip address be the one i've setup on HMI or a manufacturer default address? Then i will be able to use the same domain. Or do you still need the e designer software running to do this?
