Hi rswolff, Remeber to install the Mitsubishi USB driver if you start using the mini USB port. The driver is allready present when you have installed GX-works2/GX developer software on the harddrive of your laptop. Check this locaton: C:\Program files\EZsocket\Easysocket\USBdrivers If you goolge a little bit there are YouTube movies that shows how to install this driver. Best regards, Theo V.

Hi Oren_Yul, Codesys uses the standard IEC 61131-3 programming language. I have no experience converting from one PLC to an other but theoretically if your GX Works file is written in the same IEC code there must be a way to convert this for at least 80%. In basics the POU structure and functionblocks looks the same. I'm curious if someone here has done this before. Best regards, Theo V.

Hi DanielLeroy, Maybe this website can help you to identify the exact matching colors. Best regards, Theo V. Colormatching website for RGB: www.december.com/html/spec/color3hex1.html

Hi Donny, Did you set the transferspeed to the max. in E-Designer when you are using the serial connection to te PC? 15 minutes is rather long and I guess that you selected 9600 BAUD. This can be set to the highest speed. I agree that Ethernet is much faster than RS232. Good te read that the problem is under control and how you did this so we can all learn from this. Best regards, Theo V.

Hi Donny, That's great! How did you do it to get is up and running? Could you communicate with the default IP adres? Just courious.... Best regards, Theo V.

Hi Inntele, Thanks again. 9600 Baud should be more than enoug to communicate to the Scada computer. If the standard FX3U-485-ADP-MB module isn't working I wil look in this modem option as an alternative. Best regards, Theo V.

Hi everybody, I need to make a set up to start/stop and control the speed of a frequency inverter (Danfoss VLT Aqua) using a FX3GE PLC on an I/O base. The speed I'd like to control by using an analogue signal however, the inverter is aprox. 350 meters away from my PLC controlpanel in a second engineroom in the factory. Will this distance be a problem? Is there a smart solution to make the connection over such a long distance or is it possible with the standard analogue output from the FX3GE? I can use either a 0-10Vdc or a 4-20mA signal to the inverter. From the existing situation some shielded cables are available for the hardwired connections but the PLC function to regulate the motorspeed was built inside the frequency inverter and the other motors are located in an other engineroom and did just start/stop with digital signals without a PLC. I'm using GX-Works2 V1.98 Has anyone experience with a similiar situation? Best regards, Theo V

Hi Inntele, True, I only have a schielded 12x1mm2 cable not twisted pair available and Adam uses twisted pairs only. Today I checked out an other option, re-locate the PLC cabinet to the new engineroom and nearby the frequency inverter. That way I can start the other motors just with a contact from a local relay to the softstarter using the existing cable. This way I can be cost effective and save me a lot of headache with the connections. Only trouble would be the connection to the Scada computer but that is only 75m from the new engineroom. That should work with a RS485 left hand module and there is a cableway to that office. Thanks to all who helped me with good ideas, I really appriciate this! Beste regards, Theo V.

Thank you Inntele for this Gridcomm equipment link. I see that they also have a sales representant in the Netherlands. I had some good results with the brand 'ADAM' and Westermo to extend the RS485 to a Scada computer over a long distance in the past too. I look into it. Best regards, Theo V.

Hi Donny, You are using E-Designer I guess, If you click the SEND button at project transfer you will get the question to which Host IP you want to connect to. Is this allready set in your E1101 panel? I'm not sure if this is the first time that you connect to this panel but default there is a IP setting.192.168.1.1 subnetmask 255.255.255.0 You have to make sure the PC Ethernetport is in that same range. Also the PC and HMI must have a different IP adress (but within the same range) e.g. for te Ethernet adapter inside the PC use: 192.168.1.2 As an alternative you can set the IP first by using a USB or Serial connection with a CAB30 RS232 cable. Best regards, Theo V.

Hello all, Thanks for all this input. I think I'll try the solution with two compact PLC's like Inntele advised with a RS485 connection trough separate left-hand modules considdering the note from Crossbow about the distance >100m. That means unfortunatly that I can not use the existing cables so the budget needs to be adjusted... :( Thanks a lot, best regards, Theo V.

Dear Quarter20, Did you use the right retentive registers to store your data in? There are EEPROM buffered words and Capacitor buffered words. The battery suggestion from Colandra is also a good option to keep your data in the memory. To keep it cheap, just leave the power on but that is probably too simple... Best regards, Theo V.

Dear Ben, If you use a 32Bit instructions like DMOV I guess that you can not move the result with a 16Bit instruction (MOV). The register is just too smal to contain data larger than 32676. I don't know why this was working in the FX2 PLC but if you still have this FX2 running you can monitor the value of D12 and D226 to see the actual values in your situation. Best regards, Theo V.

Hi Flippyr, Medoc is a MS-DOS based program and will not run on Windows 7. You need a XP machine to run it or a virtual server program to emulate an older OS. Do you have the existing conveyor program on disk or in a print-out? If you don't have this you can make an upload from the PLC in Medoc but this will be a ladder diagram without labels so you will see for an example input X2 but is does't tell you that this is the start button so you need an electric diagram to see what is connected and make a label yourself. If you have the Medoc file of the conveyorbelt installation and are able tot open it you can use 'print to file' and import the file in GX-developer 8. Medoc is fun to work with, I did this for many years and still 80% of our machinery is running on this but since XP is outdated, and banned by our IT-department, I'm transforming all old Medoc software to GX-Developer enviroment or replace old PLC's for modern types like FX3GE or Q-series in GX-Works2. (My younger collegues don't understand this Medoc so 'grandpa of the team' has to do the job... ) Good luck and keep us posted of the progress. Best regards, Theo V.

Tauqeer, Yes if you start a new project in GX-Developer select the PLC series: FXCPU and PLC Type: FX0(s) and it will work for the Fx0. First make a simple program with two rungs or so to see if you can communicate. If not change the setting of the PLC type to FX0(N) Good luck Best regards, Theo V.

Hi Sailor, I checked in E-Designer the driver options (I use version 7.52) There are two drivers available to let the MAC E-terminal communicate with a "beSAIA" PLC. One is a serial driver and one is an Ethernet driver. This should implicate that you can connect the terminal to a Saia PLC but still the terminalprogram extention is not correct and the download will not start I think. The serial connection settings from the PC to the MAC terminal is RS232 9600 baud, None, 8, 1 The connection from a MAC to a SAIA PLC is S-Bus serial/S-Bus V4.05.00 If you want to give it a try you can use a serial cable (CAB30?) to Com port 2 of the MAC and a converter from serial 9-pin to USB for the PC but I'm not confident it works with the file at your D:\ drive. Look for a collegue in your neighborhood who has E-Designer installed before you spent money on this software. (not freeware) Beste regards, Theo V.

Hi Sailor, It depend on if your update is written in E-Designer too. Normally E-Designer is the standard program for Beijer MAC terminals. Looking at the file you have selected to download to the terminal it is not a E-Designer format. This will standard end with the extention ".MPA" The SAIA software is from Burgess PLC's. Best regards, Theo V.

Thank you Crossbow for the explaination, The K3X3 came from an example from my trainingbook but I could not see it trough how this would work. I assumed that the K3X3 was reading the status of the 3 input positions starting from input X3. So I assumed that if X3 and X5 where high, the reading is 2 but it wasn't. After testing at the workbench I know this was not what I was looking for and made a simple workaround with a rising edgde of the inputs X3-X4-X5 and INC D100 and falling edge to DEC D100 and compare the result in D100 with a constant value K1/K2/K3. After a comparisment [D110 = K1] etc. I made the outputs Y0-Y1-Y2 switching on/off. It worked but I'm not satisfied yet. I will try your suggestion and see what happens and see if this is easier to use and at least learn from it. Thank again. Best regards, Theo V.

Hi all, Im looking for a function to add and substract in a simple ladder program in a FX1N PLC. I use GX-Works2 V1.98c. The idea is to write a program to control the speed of a dustcollector fan in 3 steps low-mid-high speed. The more machines are switched on the higher the fan speed of the dustcollector must be and reverse. If one machine is started the fan must start too at low speed. If a second machine starts I like to add up a counter that increases a D word. If machines are stopped I like to count down and the result of the D Word must set the speed of the dustcollector by using a compare command. I tried a function [DMOVP K3X3 D3] and at the same time [DINCP D3] but that results not in adding 1 per machine (machines are conected to inputs X3-X4-X5. I like to use a PLS to the inputs to add up and PLF to substract the number of machines. I hope this explaination is clear enough for you all to make a suggestion which function is best to add and substract in the above situation. Kind regards, Theo V.

GOT1000_-_Connection_Manual_(FX3U_Ethernet)_SH(NA)-080719-B_(10.08).pdf The link shows you a video how to set up an GOT/FX3U PLC communication trough an Ethernet connection. Be sure to set the IP range properly. I suggest you programm the GOT wit IQ-Works software. To make a simple test: Place a light (lamp) on the screen from the library and set as a trigger M8013. If your communication is working properly the light should blink in a 1 second sequence. I attached the MIT manual but I'm not sure if this went wel (not experienced with attachments in this forum) Have a good day, Theo V.

Dear Wisperer_here, Maybe your local Mitsubishi distributor in Pakistan can help you out with the password problem. If you do have the PLC ladder program on your computer you can make a printout and re-type the complete program without passwords in it. It is a drastic solution but if it is your last shot just do it. Best regards, Theo V.

Hi Stevie_Ray, Check your com port settings in your Windows controlpanel. You will notice that the same Com-ports are different in virtual mode compared to Win7 mode. Just set the commsetting in your program the same as the port says in the Windows controlpanel and it will probably work. One thing i didn't found out yet is the transparentmode of the GOT using a virtual XP-machine but still you can load the files of PLC and GOT seperatley by plugging the cable to one of the devices. Best regards, Theo V.

Hi Raybbr, Did you also tried to connect trough the GX-developer that is build-in the GX-Works2 software as an alternative? you made a succesfull connection to the PLC, if you are making an upload just not mark all the checkboxes in the left hand table. Only programm and parameter should be ennough. Other functions are not available in this FX and causes error message while you start to tranfer data between the PC and PLC. Best regards, Theo V.

Hi Hayden, I don't think that it is directly possible to copy the complete project of the MAC E1070 to an USB-stick. As far as I know you can copy settings as recipe's, graphs to an USB-stick but for a full project backup it is recommended to save it with E-Designer to your computer/laptop. Just make a cable connection to the terminal, receive the project and save it to disk. By the way: Regarding to my distributor in the Netherlands (Koning en Hartman) the Beijer MAC panels are pushed more to the background in favor of the own brand GOT1000 and GOT2000 series screens of Mitsubishi. They increased prices for the MAC terminals to make it easier to stop with Beijer MAC panels. It is possible to migrate around 80% of your application from MAC to GOT touchscreens. Still I have some doubts about the migration, most of the time this is introducing problems instead of solutions. Best regards, Theo V.

Hi Knowledge Greedy, This Keithley cable is a 9 PIN sub-D connector with at one end a male and at the other end a femaleplug. It is a straight trough cable but not a nul-moden cable. Actually an old serial mouse extention cable should do the trick for you. Still I wonder how you will communicate with a FX3GE PLC. It has no serial SUB-D connector on-board. Do you use an extention module? See also the link below to the cable guide of Keithley. Selector Guide and Data Sheet for Cables - http://www.keithley.com/data?asset=4672 Regards, Theo V.
