Ron, Why didn't you use the Ethernet connection to make the online edits? Sergei, I have attached a Knowledge base regarding the Online Edit Errors. I hope thiss helps G131159624.pdf

The ML1100 also has a RCP function file and the ML1100 has online editing. I hope this helps Here is a AB knowledge base about the RCP instruction A20203.pdf

Hello, Is your back-up power tied to a input? If so, this input may be what is putting the PLC in programming mode. Check the code and the connections. The Battery Backup may be tied to the "Run" input which can be programmed in the FX2N. If it looses power it may release the input and the program puts the PLC in run mode.

You may not want to wait this long, but the next release of RSView Studio will be able to upload and modify the .mer files. swimmy

If the RSLogix was purchased by your company you can transfer ownership to another person. Here is a link to the site: http://www.software.rockwell.com/support/regtrns/ You do not need to purchase a new copy of RSLogix 500, just sign-up for the Tech-Connect and you will be able to download the newest version. I hope this is of some help. swimmy

Here is a discription of the RSS feed that I found at www.RRStar.com After reading the description, I now understand what RSS is and how it works.

Claud, I had a similar problem last year with a PVP 1250. Come to find out I had a Compact Flash card in the external CF slot that was Formated Fat16. The compact flash has to be Formatted as Fat32 in order to function properly. I removed the Compact Flash card and the message about a corrupted Firmware did not return upon a powerup. I hope this helps. Swimmy

Not a problem. I hope that this will help you get the job done. swimmy67

Being that the VersaView 1200P is a Windows XP Pro computer, the first thing I would check is to see if the cooling fans are still running. Heat will cause the computer to freeze. It may be advisable to schedule a cleaning and inspection of the computer. Remember, the VersaView 1200P is still a computer. It may be a "Industrial PC", but it is still a computer. I hope this helps. swimmy67

TW, I thought you were looking for a 0-200uA converter. I suggested a Calex module that was 0-20mA but that was wrong. Panic suggest a 0-20mA and you tell him it will work. What gives?

TW, We use Calex modules. They might have what you are looking for. Here is a link to their site: http://www.calex.com/ swimmy67

so that you can select the correct file.I hope this helps.

I was reading this post and thaught I would try and find some information o nthe port splitter. Attached is the product profile for the 1747-DPS1. swimmy67 1747_pp018__en_p.pdf

I have one question, Why are you using a 1747-PIC module to connect to the ML1100? You can use the RS-232 programming cable that is used to program the ML1200 and the ML1500. The ML1100 can also be programmed by the Network port, only after a download from the serial port. swimmy67

You can also use the FROM instruction to get information from the FX2N-2AD module. Attached is the FROM and TO instructions taken from the Mitsubishi FX Programming Manual II. Please share your comments and code with the Forum. swimmy67 From_and_To_instruction.pdf

I think you have to initialize the fx2n-2ad card in your program first. Have you read the user guida that came with the module? I have attached the user guide for the fx2n-2ad module. swimmy67 FX2N_2AD_Users_Guide.pdf

Cristian Were you successful in establishing communication from the PLC to the Inverter? We are just courious to see how things worked out. swimmy67

Have you checked the cable from the PLC to the Inverter? Have you written the code for the communications? I see that you can communicate with your PC because you are using a different cable. You need to verify that the cable from the PLC to the Inverter is good. The code has to initiate the communication and receive a responce. The Inverter will not try and communicate with the PLC. I have attached a working program that I use on my machines. I am communicating with 4 inverters. 1 FR-A540, and 3 FR-E540 drives. The attachment is in a pdf format. Pay attention to the RS command and the timing of the communication logic. I hope this will help you. swimmy67 FX2N_to_FR_A540_and_FR_E520.pdf

What brand of inverter are you using? Attached is a communication troubleshooting page that I made up for a Mitsubishi PLC and inverter. I use a FX2N with the FX2N-485-BD. swimmy67 485BD_Comm_Check.doc

Are you running any antivirus software? The EVRSI file residing on the C:\ drive will get corrupted from the antivirus software scanning it. Rockwell recommends to put the EVRSI file in the exception list of the antivirus software to avoid scanning it. You may have to reset your master disk, this can be done online. Delete the EVRSI file from drive C: and then move the activation back to drive C. swimmy67

Patriot, If you are using a 20 Hp motor then the FR-F740-00310 is the drive to use. Is the 20Hp motor going to be used for a heavy duty application? Then the FR-F740-00380 is the drive to use. Look at the ratings on page 3 of the manual that TW posted a link to. For the drive you are using it lists a 75amp breaker. If you look at the specifications on page 90 you will see the maximum output and the input kva. Base your breaker on these ratings. I have been using Mitsubishi FR-A740 drives and I size the Breaker to the rated amperage on the nameplate. For example I use a FR-A740-00230-UA drive for a 15Hp motor. I install a 50 amp breaker for the drive. The breaker for the Drive has never triped at powerup. The new numbering systems of the Mitsu drives has the current rating in the part number i.e. FR-A740-00230-NA means 23 amps. For the Kw ratings a 11Kw is equal to a 15Hp motor. 15Kw is equal to a 20Hp motor. 18.5Kw is equal to a 25Hp motor. 22Kw is equal to a 30Hp motor. swimmy67

Patroit, With the input current rating of the drive, this should be the fuse or circuit breaker rating. The input rating is the maximum current of the drive. I hope this helps, swimmy67

The GT1000 programs with a standard USB cable and you can program the Mitsibishi PLC, if connectrd to the GT1000, with the USB cable through the GT1000 touch screen. The GT1000 HMI will allow you to passthrough to the PLC while still operating the touch screen program. Also if you are using a Mitsubishi PLC the GT1000 will upload the ladder diagram and you can monitor or even change some settings without connecting your laptop to the PLC. I am not sure of the features of the E- terminal as I have only used the GT1000. The GT1000 I feel is over priced and it still has touch cells instead of analog resistive touch screen. The use of the touch cells means that a button must be a certain size and in a certain position. I hope the information I have provided helps you. Thanks, swimmy67

I agree with Crossbow. The programming software for the Mitsubishi PLC is very powerful. While I have been checking the Siemens Programming software, it feels cumbersome. The Siemens Representatives visited my facility and were touting their software as being user friendly and very easy to program. From what I saw the programming software is not very user friendly and not at all easy to program. Some people like the Wizards that are incorporated into the programming software, but I feel they are a waste of time. Granted, the Wizards generate the code required but some of the code can not be viewed beacuse it is Siemens Protocal. I like to know what is going on with my program. I do not want to rely on something that I can not see to run the program. Here are some things that I personally do not like about the Siemens Programming software: 1) The components can not be double clicked on to bring up a dialog box to be able to change or enter information. 2) There is a set number of "Networks" that are in the Ladder and when these are used then you have to insert new networks to be abld to continue with the program. 3) There are way to many Wizards in the programming enviroment. 4) The programming enviroment should be user friendly. Siemens MicroWin is far from user friendly. 5) There is a big learning curve invloved with the Siemens MicroWin software. 6) Drive communication is Siemens Protocal. USS. If you want to communicate Modbus/RTU there is required a separate module. 7) The RTD module only has two inputs. To get four RTD inputs, two RTD modules is required. The Siemens, I see, does have a Ethernet module and a Modem module. With sending our equipment around the world, it is a requirement that I be able to communicate with the PLC with either Ethernet or over a Phone line through the Modem or even a cell phone modem through serial or Ethernet. swimmy67

TW, If the activation is currently on the hard drive, use the EVMOVEW.exe located in [ start, program files, Rockwell software, rslogix 500]. Insert a blank floppy disk. Move from drive "C" to drive "A". How is this for an answer? swimmy67
