It's been ages since I used E-Designer, but have you tried removing Transparent Mode from the Ethernet connection just as a test?

Hi! First of all: I'm assuming you have developed the code using MC 4E frame coding. Your request is not correct, I have only looked at the beginning: 540000000401..... (04 and 01 are both supposed to be 00 00) since they are [fixed] in the protocol spec. The last two bytes of the subheader are always 00 00 and not 04 01 like you have. So you should start with checking your initial request. Also: What does the asterix in your request/response indicate?

Do you have the original source code, or is this an upload from the PLC directly?

@Mani1424: You should start a new topic instead of hijacking someone else's topic when you are asking new questions. To answer your question, FIFW/FIFR (standard FIFO) will get you started. Post a new topic if you get stuck.

Again, could you post a screenshot of your peripheral config (see attached example).

What is your computers IP address?

Is AppDataTransfer (see picture) enabled in your application?

If I understand you correctly, you can reset the HMI and then download your project. However, after the first download you are unable to download to the panel again. You have to reset the HMI all over again to be able to download your project. Is that correct? Can you post a screenshot of the peripheral settings (all the ports)? My guess is that some settings are modified from the original, and therefore you cannot connect to the panel after the first download.

How are you downloading (via Ethernet or other communication)? Can you post a screenshot of the peripheral settings (all the ports)?

@David le: What do you mean by this? You haven't posted any questions before in this topic, and you don't describe what it is you don't understand. If you have a question, please ask it, otherwise start a new topic.

You need to calculate where the start addresses are for the specific node, based on the Station Information settings. For example: Slave 1 = 32 I/O Y1000-Y101F Slave 2 = 64 I/O Y1020-Y105F Slave 3 = 32 I/O Y1060-Y107F in other words, in the example Slave 3 will have a start digital output address: Y1060

It may also be that the HMI is simply using PLC data as a memory "container". Simply a storage space instead of using the internal variables of the HMI. I cannot guess why this has been done, and it sounds very strange, but it is possible. How did you verify that e.g. D14 is not being used in the PLC (but used in the HMI)? Note that variables doesn't always show up in search if they are used inside arrays. One example could be that there is a "HMI system array with indexing" from D0-D100 which is being used in both the HMI and the PLC. That way, D0 will show in search, but D14 will not if it's addressed e.h. D0Z1.

If I'm not mistaking your question, I would suggest a mechanical "cover" of some sort, hinged to the electrical box above the HMI. That way it can be lowered/raised on demand. Maybe talk to some mechanical guys? Or am I missing "the point"?

Yes, you can use it in Simple Ladder Mode, as long as you have "Labels" activated in your project. By using "Labels", you make sure that there are system variables available for random assignment, which these function blocks need to utilize. By activating "Labels" you can import the FB, and use it in your Simple Ladder code.

Hi! I do agree with @glavanov, however if you provide some more information like he suggested it would be easier to point you in a direction... It's often easier with "more minds" on the case when debugging random problems, so feel free to share some more information about your application. We'll ask for more if needed.

Great, no problem

Great. If "allowable" by your dealer, it would be great if they could share or you could upload the FB's... Probably others who will need this functionality.

I'm not sure if the built-in Ethernet port of the FX5U can act as a ModbusTCP Server ("slave"). I thought it only operated as a Client ("master") using the Pre-Defined protocol function. It could of course be that the functionality is bult-in be default in the port. Have you tested if you can get a connection to the Ethernet port by it's IP address, using a Modbus tool of some sort?

Yes, GX Developer (at least the last 5 versions released) supports FX3U.

GX Works2 must be purchased from Mitsubishi. I'm not 100% sure, but maybe there is a DEMO version of GX Developer (which can also be used for both CPU types).

You need to contact your nearest Beijer Electronics department to get the firmware loader and file. Check out their website: https://www.beijerelectronics.com

In addition to Motor:=FALSE; you should set the timer low again by adding the following line above or below: MY_TON(IN:=FALSE); In other words: ..... MY_TON(IN:=FALSE); Motor:=FALSE; ..... That way you will also reset the timer.

If you are talking about GX IEC or GX Works2 function block diagram it's not possible to convert from simple ladder to function block diagram. If you are talking about GX Developer SFC that is also not possible. Why did you develop ladder code if you want function block diagram?

What HMI were you thinking about? Most HMI's have DataLogger functionality (check the specs), and an export function of some sort to save data to USB stick. Which HMI did you have in mind (any particular one)?
