Below is a sample code for GX Works2  providing Modbus TCP/IP Client or Server functionality to QnUDE-series or L-series PLC systems with built-in Ethernet ports.  https://www.dropbox.com/sh/mtcjzlod7phfsns/AAC3Cr0Tz-M83zvEz5tSTAGXa?dl=0

Good morning You can't read structured projects from the PLC unless the symbolic information is stored in the PLC. Most programmers does not write the symbolic information to the PLC due to space available in the CPU. You will require the original program.

Good morning I trust you are doing well Below is a link for GOT training videos and a manual you can download. Part 3 covers the GOT https://www.mitsubishielectric.com/fa/assist/satellite/index.html You can also go to the link below for some additional training  https://www.mitsubishielectric.com/fa/assist/e-learning/eng.html  

Good day Sir I trust you are doing well The analog module you are using cannot work with sinewave signals. The module is rated -10VDC to 10VDC Please see attached manual for the module 12433.pdf

Good day You will have to save the Program on your local machine.

No problem Have a good day too

Good morning I trust you are well Please see link below with programming samples for Modbus TCP for IQ-F and IQ-R PLC's https://www.dropbox.com/sh/fi01zx0rr29vkz9/AABKu1oaa1mFihZDX6teaM1_a?dl=0

Good morning Please see attached manual and ladder sample for using greater or equal function. To access the function you need to type and<= and then your variable and then your setpoint. When you use a GOT to change the setpoint you can use a register. When you use a constant then you put K18000 as per example. K18000 will be a fixed value.  https://www.dropbox.com/sh/334n9g7liyk3l6y/AAAijUVidxY7eMINhijbyxWOa?dl=0  

So below is a sample of the Greater and Equal than function M8000 is a always on bit in the PLC. As long as the PLC is in run mode this bit will be on. D1 in my example will be from you analog D0 is your setpoint M5 is your output So when D1 is equal or greater than D0, M5 will be high. When D1's value goes below D0 setpoint value, M5 will be low

Good morning. I trust you are doing well What model of FX PLC do you have?  I will quickly write you some sample code on the comparison to switch on bit M5. Once I know what FX PLC you are using ill send you the relevant documents on the analog

Good morning Just some thoughtful notes regarding this problem. 1. PLC will need a battery installed to be able to store the values. 2. You will need to assign registers to the Latch 2 area to be able to have values available after a reset. Latch 1 will keep the values for a power failure but will clear when doing a reset. Latch 2 will keep the value till its cleared or over written. All Mitsubishi PLC's except for the Alpha range and FX5UJ has the same latch functionality. To access and setup the latch settings you need to go to the CPU parameter settings in the navigation bar. 

Fully agree with you. I come across a lot of installations that is scary dangerous. It sometimes makes me think that somehow a system needs to be implemented same like you need a wireman licence for instrumentation too. But companies are also at fault as they don't even know what the regulations is. It makes me sick to think I studied for 6 years and every second guy of the street is my competition.

Good Morning I would suggest installing a fuse on your supply to the PLC. If you are using the power supply of the PLC for your 24VDC please install a fuse there too. I often see beginners damaging PLC's due to there lack of electrical knowledge. Please see the installation manual for your PLC.

Good morning I trust you are well.  I would suggest shortening your time. Please see attached picture on how to calculate the time  

Good morning Sir I trust you are doing well. In GX Works 2 you can go to the Tool tab and from the dropdown you can confirm memory size. In the memory capacity calculation result screen you can chance your display option to steps. This will then show how many steps you have used and what is remaining in the device memory.  

Good morning Sir.  I trust you are doing well.  The FX1N does not support Modbus communication. I have attached a link for you with the Mitsubishi documentation. https://www.dropbox.com/sh/dmlmfxhsslmtqwx/AACu4qvID8R83r8Q1hJne0XQa?dl=0 This documents contain all the serial communication.

Good day Sir You can check the battery status by using the I/O monitoring in MR Configurator 2 The Bit BWNG is a battery warning bit.  Another test you can do is to leave the machine on overnight, if the servo have not lost position then you know the battery is faulty.

Another point is the FX5UJ only has a program capacity of 48K Steps compare the to FX5U that has a program capacity of 128K steps which can be changed on later versions

Good day Sir It sounds like you have a battery issue. Please check and replace the battery. 

Good day Sir One option you can have a look at it to use a SD Memory Card. You can story your FB Files on the memory card instead of on the PLC memory. The CPU will read the FB then from the memory card. Please refer to your e-Manual Viewer for more details

Good day Sir I trust you are doing well I had a look and the FX5UJ has a memory limit of 35K. User defined function blocks use up memory quicker that writing in standard ladder. If you do run out of memory you will have to consider a bigger PLC or changing to use ladder instead of function blocks

Good day.  No problem

Good day Sir The Simulation function is not supported for the FX5UJ CPU Please see SH081215ENG-2DB8 in e-Manual Viewer for CPU versions that is supported by the Simulation Function

Good day Sir I trust you are doing well. I have just checked on my side and see also that with the FX5UJ PLC selection the simulation does not work.  Ill Email Mitsubishi Europe now to rise the problem. As soon as I get feedback ill give you an update

Good day Sir No problem. Glad I could assist
