I'm not sure I fully understood your setup. Do you have an existing Q12 (GX IEC) that is working as it should with JP_READ, but when "converting/upgrading" it to the Q13UDEH (GW2) it will not read/exchange data using JP_READ. This is the problem? What are you reading data from? Which CPU and what is it developed in?

I don't think there exists any free open libraries for this. However, you should be looking into ModbusTCP which has loads of free libraries/classes for C# on the internet. I don't remember if FX3U-ENET-ADP supports ModbusTCP, but there are libraries for the non-ADP module from Mitsubishi, and most built-in ports from Mitsubishi now supports ModbusTCP. Which CPU are you using? It's fairly easy to develop on ModbusTCP so this is a good and solid choice.

As @Knox writes there is a software for this. I use FR Configurator2 which also includes FR-A740. You can do "everything" from the software, and you connect to the inverter via the built-in USB port and a USB cable.

Can you take a screenshot of how "Key Customize" looks like in your version? And which version are you using? My guess is that it should work anyway. Also, as @nehpets states, why haven't you updated to the latest version?

As Gambit states... See picture under Key Customize... At first glance it "looks" wrong since some of the ladder symbols are "missing" shortcuts, but if you just test it you will soon find that everything works as it should.

I would say it depends on your application. I've used A800 with encoders, both one single axis (feeder board), and also 4 together (elevator application). If you don't need high-speed point-tables, cam-control/virtual axis then it will most often work with frequency drives and original motors... What's the application?

It would be nice to also have a screenshot of the error code, including the error number. Have you made the remote PLC work (the one with Coax cable) - "N01"? You should start with making one of the networks work, then proceed with the next one to be sure that you are debugging in the right place.

It was a good thing you are a "chickenkiller", and NOT a "catkiller", as I can imagine by panic_mode's picture he/she would be quite upset...!  I agree with everything that @panic mode writes, and would emphasize SCAN: PLC's are scan-based and NOT event-based. This is basically often the first pitfall of many non-PLC programmers. A returning "issue" for people not familiar with scan-based programming is how to correctly debug for example a bit that is constantly set to a state (high or low), without the use of breakpoints. I normally recommend to use a temporary bit and a SET/RST or alternatively a MOV instruction together with the "problem" device, so that you can see if, in the specific line of code, the state is what you expect and if the device is being modified later down the code.

We need screenshots from the network parameter setup you have in GX Developer... It's a bit hard to help out without knowing what config you have downloaded to the PLC. As a side note; you do realize that you are rewriting the code to a CPU that has been out of production and spare parts for years...??

You need to purchase GT Works2 from your Mitsubishi dealer/representative, it's a paid software.

Hi, sorry for the late reply. Set IP to 255.255.255.255 (accepts all incoming IP's), and port to 65535 (accepts all incoming remote ports) I'm not sure how the SCADA setup looks like as I don't have MAPS or Citect... Can you find out if it's possible? Should be set to UDP and IP of the ENET module...

Hi and welcome! Can you take a photo of the error message/display on the screen?

First of all, Diesel is hazardous so I would suggest contacting a distributor of sensor equipment to get a suitable sensor for your application. When that is said, you can mostly use any kind of sensor and just calculate the level in the tank. To take an example with a pressure transmitter you would need to know the min/max level of the pressure transmitter, and calculate what level of pressure corresponds with what level of height in the tank. Example water: Sensor 0-10bar equals 0-10m of water (regardless of diameter in tank). Diesel has a different viscosity and would be a little different...

By selecting UDP connection, you can connect several clients to the same socket (e.g. Citect/Maps...)

Hi again, Not sure why you decided to go with Socket Communication instead of ModbusTCP, but in both cases you can read and write devices in the PLC. You need to go into the parameters of the Ethernet port, "External Device Configuration" and add the elements you want to use for comms. For ModbusTCP you would need "Modbus/TCP Connection Module", for socket communication, select the one that suits you (I always prefer UDP for socket comms since error handling is built into the protocol already and causes less network overhead).

It looks like the original attachment in this topic has been removed (it's no longer available for download). I don't have the files either, but I bet that colmid50 have them. You can try to contact him directly via the message system here in the forum (I don't know his real ID/address) - just click on his name ("comlid50) and press the "Message" button - hopefully he is still active. I don't have any better suggestions. Sorry.

You can use ModbusTCP. There are tons of free examples of ModbusTCP implementations for VB.NET on the internet. Your VB.NET will need to be the client ("Master"), and your FX5 will be the server ("Slave"). You can setup the areas for read/write in the parameters of the FX5. That way you don't have to deal with MX-Components, and you can find a lot of information for free on the web.

You can use "MOD" instruction to check if it's dividable by 2: MOD D3012 K2 -> NE 0 -> "FlagIndicatingOdd" If you receive the flag, it indicates that you have an odd number, and you can remove the 8 bits and possibly generate a number of words increased by one (compared to the division by 2 earlier).

Does it matter since the gap is obviuously located between system setup range and measurement range? What I mean is that 754...763 is multiplier factors, model code and so on which obviously does not have anything to do with realtime measurement, while 768...788...xxx is the realtime measurement area where you want to do the high-speed calculation. So in other words, I would read-out 754...763 during startup of system, and then continously read 768...xxx for measurement purposes. Or am I missing something here?

You are correct that "." are limited to specific addressing only. The way "around" it is to define variables in global lists and then use the variable name (you can assign a labelname the address D100.1 for example).

As Gambit states, it's not possible to use ModbusTCP Server (slave) in the R-CPU as of now. But if you must have it the way you are describing it (Q = Client/Master and R = Server/Slave), then you have to add some components in order to communicate between them. I would do the following if you "must" do it your way: If you already purchased the R-CPU, then also order an Ethernet card RJ71EN71. Alternatively if you haven't purchased the CPU yet, just replace R04 with R04EN (which has 2 built-in extra Ethernet port that can be configured with CCLinkIE Field. Buy a Modbus Server (slave) <-> CCLinkIE Field gateway to convert between Modbus telegrams and CCLinkIE Field network; https://www.anybus.com/products/gateway-index/anybus-xgateway/detail/anybus-x-gateway-cc-link-ie-field-slave---modbus-tcp-server Hopefully you haven't purchased the CPU yet, since you can just select the R04EN CPU with 2 extra built-in Ethernet ports which can be configured as CCLinkIE Field ports (or regular Ethernet ports).

So you have not set ANY other parameters in the amplifier, and you're using DIO for positioning data, can you disconnect IO from the amplifier, and just use MR Configurator. Boot the amplifier and turn some revolutions, monitor the value, reboot the amplifier and see if the value is stored. This is normally very easy, just connect the battery and set parameter: Absolute positioning is working

We cannot see any picture(s)...

Which parameter(s) did you change, and to which value, to enable absolute positioning?
