    Hi, i need to modify a program in rslogix 500. I'm use to using mitsubishi's gx developer, so i base my experience on veryifying, going online and downloading from this. So first of all, i want to verify this existing program is the correct before i do any modifications, then do a download. The PLC'S that are used are SLC500's one with serial and one with ethernet. The mod i will be doing on one PLC is replacing an existing analog input card with a digital input card. The other PLC i will be modifying will have code added, so i can read an analog input then output this value to SCADA. Can one give any advice on the steps to do this? Ive had a look at a few youtube videos but just need a little more expert advice. Thanks Stu

    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

    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, 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, 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, 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, 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, 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

    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?

    Hi, i use Siemens (i know you can upload the code from the plc with no comments etc) Beckhoff (no option to upload) and Mitsubishi. I am correct in saying with some PLC's you can upload the code, then you can download that code to go online and monitor whats happening. or can you upload the code, saying if you have no source code and go online at the same time. Just trying to get my terminology correct. Stu
