  1. As part of a startup initialisation I want to set some 400 memory tags to a string value. I use this routine: Public Sub WriteValue(val As Variant, TagName As String, Fm As Display)     Dim TG As TagGroup     Dim WriteTag As Tag         Set TG = Application.CreateTagGroup(Fm.AreaName)     TG.Add TagName     Set WriteTag = TG.Item(TagName)     WriteTag.Value = val End Sub   It Works well - but it is slow. Making about 400 writes takes 40 seconds. I thought maybe the creation of a taggroup before every write was slow (like it's done with the use of this WriteValue routine), so I tried making a taggroup with all 400 tags first, set active=true for this taggroup and then do all the writes. But it's equally slow. How do I speed up the writing of such memory text tags? I have a had similar read-issue - here the many individual reads is slow, but if I create a large taggroup with active=true - then reading is fast.   I use FTview SE 7.0 on Win 7-64
  2. I would like to send a character on a Micro830 using ASCII. I wish to send the character to a pc by using Real term or terra term on PC. Can somebody please let me know how can I configure the ladder diagram, I tried various commands including THE AWA, AWT and also the MSG_modbus however I can initiate the communication. I think that I am missing something cause I don't have a reference ladder diagram. Thanks 
  3. Beckhoff 2.11 simulation mode

    All, When i work with a 2.11 IDE from beckhoff in simulation mode i must everytime when i change a input give a write commando. I think it must be possible that the outputs changed automaticly when i give or change an input. What do i wrong?? best regards Frans
  4. 1769-ASCII

    I'm using a 1769-ASCII and need help with one part of it.  I have no issues with sending data.  The manufacturer shows the following as the process...   My question is: how do I evaluate the XON\XOFF?  The machine states "This communication protocol tells the status if it can receive any data or not to the host by sending "XON" (HEX 11H) or "XOFF" (HEX 13H) to the signal line."  I never receive any data so I'm not sure what's wrong or if what I'm doing is correct.  The attached file is same code downloaded from AB's website which is what I based my code off of.   http://search.rockwellautomation.com/search?client=samplecode&oe=UTF-8&ie=UTF-8&output=xml_no_dtd&proxystylesheet=samplecode&site=sample_code&getfields=*&lang=en&hl=en&sort=date:D:L:d1&wc=200&wc_mc=1&ud=1&filter=0&q=ASCII   62119.exe
  5. Hello Everyone, I have a Omron CJ2M PLC, and I have configured the Ethernet/IP port of this PLC to communicate over ethernet connection. I want to read/write the DM, HR memory areas of Omron PLC (CJ2M) using eip protocol communication. Is there any protocol specification which explains the telegram structure to be sent over ethernet to be able to read/write the values in omron plc over EIP? I want to know the command structure which can be sent to PLC and PLC will respond with the proper response. 
  6. Would someone please help me how to convert an integer to ascii?   For example if the output tag is an ascii string, of 3 characters and my numeric input is integer.   When user input a value of 5, I would like the input value to be convert and assign to output ascii string tag of "005".  How do I set the conversion format in either tag assignment or tag expression?
  7. ok i have a rotary encoder to a HSC on my tm221, im converting that to ascii and outputting the value to a lascar HMI over rs232. example of value sent: 1234     value received: 2143 there don't seem to be any options to set the LSB or MSB , any ideas?? Dan
  8. ASCII Code 8 Byte In Twido

    Hey Guys!!!! I'm trying to use ASCII 8 bites in TWIDO PLC and on MOD BUS TCPIP it connected to WinCC , where I'm trying to read the ASCII in as a STRING char that to in 8bits. The problem I'm facing is that it is getting swapped like if I'm writing VA in PLC then on SCADA it is showing AV. In WinCC there is no setting for word swapping. Therefore Kindly help me for this in plc end

  10. GX PLC RS232 Communication Code

    I have been using Mitsubishi PLCs for the last 17 years and to be honest whenever I need to shift data I generally use an Arduino. But I have existing PLCs that each need to be connected to a PLC running Biometric Readers. The handshake between the PC in a box (running the biometric readers) and the PLC (running an access control turnstile) will be 8 bit ASCII code via RS232 connection. I am struggling to find any working examples of code to run an RS232 BD card on an FX3G PLC, I have set up an FTDI RS232 UART and I can see data coming in from an Arduino but I can't get the FX3g to send any data via RS232. I can't even get the PLC to communicate. Unfortunately the tech support offered here in the UK is awful. Any help would be appreciated. Regards Julian    
  11. Hello, I am using an NJ301 PLC with an NA series HMI. I am communicating to the PLC via FINS protocol using the DotNet FINS UDP application by Jay Anthony found under the downloads section. I am finding that when I write a string to an address, the bytes order are reversed. For example,  I am writing the string 'Test' to variable 'FINS_String', which is a String data type at memory address D20. My FINS command is the following: 010282001400000254657374 0102: Write 82: Data Memory 001400: Address 20 0002: Write 2 words 54: T 65: e 73: s 74: t The value that appears on the HMI and in the watch window is 'eTts'. If I write 65547473 (eTts) as my command, it appears correctly as 'Test' on my HMI. I debugged the application and I see that the byte array is being sent in the correct order, so I'm not sure what the matter is. I can't imagine that to pass a string through FINS protocol the hex values need to be switched every time.  Any help would be appreciated. Thank you for your time.    
  12. 1769-ASCII Setup Help

    All, I have a 1769-L24ER-QBFC1B processor with a 1769-ASCII card that I am trying to get working on the bench. I have a standard serial cable hooked up from Channel 0 of the ASCII card to the COM1 port of my computer. All I'm trying to do at this point is a simple bare-bones hello world program with a terminal (termite or putty) so that I can verify my setup and understand how it works before I try to implement it on the plant floor. I have the card set up in alternating mode and am using the pre-canned program found starting on page 35 of the user manual(1769-um012) .This is my first time using the ASCII card I am familiar with the CompactLogix processors and the RSLogix Suite. Any insight you can give would be greatly appreciated. Thanks, Lucas
  13. I have a Micrologix 1400 and one PC which sends 102 Characters in RS-232. I need to read all characters with Micrologix 1400, Is there any way to read all characters? I know the limit of ARL and ARD instruction is 82 characters. I do not know if two ARD instructions could read all characters. Do you have any experienced like that? Could you help me? Thank you in advance
  14. hex to ascii

    I need to know if there is an easy way to convert a hex value to ascii without going through all of the math. In the ContolLogix 5000 software, I can find how to do a string to decimal (STOD), but the problem is the initial value. For example, the hex value for ASCII 3 is 31, ASCII 4 is hex 32, etc... If I do a STOD to create a string from the value of hex 31, I get a string of: '31'. I need to send this value out to hyperterminal and read a 3, not 31. If it was only reading one source and did a simple subtract and mov commands for the values of 0 through 9, that would not be a problem. However, my problem is that I am continuously reading multiple valuses from several sources and I don't want to have to write the code for each character from each source. I could do and AOI or UDT, but isn't there a simple instruction in the logic?

  17. Sending Ascii from PLC

    I have an omron cp1le plc and a sato s84ex printer I need to learn how to send print jobs to it. I know I can use the Serial card option and send the code to the printer over RS232. I am using the NiceLabel software and printing to file which extracts the SBL code. That is where I am stuck. What part of the code do I use and where do I put it in the CX-Programmer. And what instructions should I be learning to send Ascii to the printer. I am very new at all this and just want a few hinters and direction. Thanks.
  18. I am needing some help developing a string, and setting up communications that will be interpreted by a printer. I have thus developed my string, setup my com ports on my 1766 micrologix and setup com ports on my schmidt styliner scribing printer with win7e. Essentially this is plc to computer running software for a printer. the software has been setup to the best of my knowledge. My problem is creating a string that will be recognized as start/stop transmission at the printer. I have never done ascii so I am unfamiliar with how to get the two components talking. This is a simple application that only requires writing a string to the printer, but i have tried all that i can without any luck.
  19. How would I use "ASC-String Search", ACN-Put 2 strings together, ACI-Convert Integer to String" from rslogix500 and the micrologix series PLC -- with the Micro800 series and "Connected Component Workbench" ?? I'm trying to convert an Micrologix 1100 communication package to the micro800 series. I think it can be down if I can figure out how to convert ASC, ACN, ACI, into functions for the micro800 plc. Would appreciated any ideas/help you can offer. Thanks
  20. Hi all and nice to meet you here! I hope that someone with experience helps me and I hope in future to offer also my help to someone. I am having problem with a Mitsubishi plc with A2N (S1) cpu installed on a machinery. The machinery stayed 20 days switched off and with battery empty as I realised when switched on and the problems come out. I changed the battery but the problem didnt resolved. The plc gave error with stable error led and flashing run led on the cpu. Also an error led stable on a (double role) module of printer and ram. I have to say that I have never used GX developer environment before and it is my first contact with Mitsubishi plcs. Reading some manuals (found on the internet) and by using GX developer I read from plc the faults. Register D9008 was set at 12 error meaning MISSING END INS. I Followed the described flow charts from a2n manual for reseting faults but the situation was the same always as described above. I tried to read the program from plc and succeded to read it. It is a lader with about 6000 lines. Anyway I have no previous experience of the GX development environment but I tried to put the missing END in the program as sugested also by the flow chart in the manual. At this point I have to say that it was automatically added from gx developer as I can remeber from an appeared message. I verified also many times the program on gx developer with the plc and the only difference was that missing END at the last line of ladder program. Anyway I tried to write back to plc the program with correct end but it was not possible. I tried several times. The error mesages took with Gx developer was the following : "THE SAME T/C COIL EXISTS IN PROGRAM (MAIN) AND/OR PROGRAM (MAIN-SFC). THE VALUES ARE SET TO BE THE SAME AS IN THE FIRST FOUND T/C COILFROM THE TOP OF PROGRAM" "THERE IS A DEVICE IN THE PROGRAM (MAIN) THAT IS OUTSIDE OF THE RANGE. CHECK THE PROGRAM AND CORRECT THE DEVICE THAT IS OUTSIDE THE RANGE." Anyway I decided to delete the plc memory. After that the run was stop blinking and the error led went off. Only the error on the printer-ram module was on (This module was changed with a know functioning one witout any variation on behaviour). I thought that problem has gone now that the cpu is empty. I tried again to write the program to the plc but again i take the above mentioned messages. Now I have an empty plc and a program on the Gx developer that cannot be written to plc!!!!!!!!!!!!!!!!!!!!!!!!! I am desperate!!! I do not know how to proceed. I am not knowing the mitsubishi development environment. Other than Gx developer I tried to install the GX simulation but it not works to my computer. At this point I dont know even if the ladder program is somehow corrupted after the described above messages. I can sent the code (GX developer project) and any other information to someone expert, if necessary, to have an opinion. Please help!!! Let me know how to proceed!! I have to write back the code to plc !!!!! Thank you all in advance!! Now i realised that there is SFC that is my problem. Could someone help please? Big part of ladder is in yellow color. How can i proceed?
