  1. Does anyone have an example piece of ladder logic, created on a Micrologix 1200, using ASCII to READ and Write to a serial device?  I am building a ladder on a Micrologix 1200 that will send data to an old CNC once a certain ASCII instruction is received on the PLC.  For example, when the machine spits out an ASCII "1", the PLC will see the "1" and send out a three digit number depending on a sequence of discrete inputs.   Thank you,
  2. Fuel tank level automatic report

    Hello, I have a fuel level reading system in a 2000 gallon diesel tank. the system has a slc 5 05 of rockwell.

  5. SCPI Communication

    Has anyone been able to set up back and forth communication with a device that uses SCPI? I have a D2-260 and 5 Kikusui power supplies. The PLC already utilizes a RS485 Modbus network and also has an Ethernet connection. The power supplies only have a RS232 connection and uses SCPI commands. I have searched the web over and there are Modbus to ASCII converters but how to make it where to catch the response in a register for the PLC to find? I am open to anything, 5 small PLCs to there is no possible means to do this. Any direction would greatly be appreciated!
  6. good day! I would like to put some ascii code in a device: D3000..D3009 has to be filled with 0x5F54 0x4F5F 0x4150 0x6F73...  ("_TO_APos")  When I fill it using an ascii-input-field in the designer and press "enter" it works. But I would like to put this text automatically in D3000 and following register, when the user press a switch-object. I tried with an 10 actions  "keycode" but I don't see how to say that the key code shouls be saved in D3000. Can somebody tell me the best way to fill more word devices with only one object switch? Thanks in advance   MEBoerner  
  7. My client is a pharmaceutical company and they want to interface their Blood Gas Analyzer (which is a RAPIDPoint 500) to a Controllogix PLC via EtherNet. I have attached a Spec that I found, which gives the initial information you would need to do this. It says that the BGA can transmit data in ASCII. However, it doesn't list what bits I need to send to the device in order for it to send the PLC the data. I've tried contacting Siemen's (who makes the BGA) and they were useless. I also tried searching the RA knowledgebase.  Does anyone have any insight on how to communicate with a device in this way? Thank you Tyler RP500_LIS_5_20_13_-_Rev_C_.pdf

  9. ASCII !@#$!@#(*&^

    Hi Guys, I need help/advice.  First, I'm not new to PLC programming and design. I've been doing this for 30 yrs.  OK that said, 30yrs ago I cared about things like PLC5 serial communications sending ASCII characters as it was a common thing.  Well, I've slept and drank a whole hell of a lot in 30yrs so I really don't care now but I need to do it again. I'm working on a PLC5 to Control Logix conversion.  The company will not update this ancient chamber environmental control.  So, the ASCII coms need to stay.  The old PLC5 took the command string to change the temperature and did a AWA command and out port 0 the new temp setting went.  Logix however, it is not that pretty.  I'm using a Prosoft Technology PLX31 Ethernet to ASCII.  My problem is, the Prosoft device data table in the Logix is data type SINT.  How do I get the command string "L1S"+temperature value, example 27C, so the command would be "L1S27" into the data type array of SINT.   The header is constant.  The only thing that changes is the digits.  So would you guess I convert the L & 1and put those in the first address, S and the first digit of the temperature in next address and the remaining digits in the 3rd word?   Perhaps I'm making it all too difficult.  From what this old memory is telling me, I need to convert each character into the ASCII Hex or Decimal equivalent.  So anybody out there still familiar with this s....tuff? 
  10. Hello everybody, I have network from : PC - PLC - I change this option in FX5U PLC in GX Works3 for Network Ethernet port --> Application Setting -> Security -Disable Direct connect with MELSOFT : Enable/disable -DO not respond CPU module search : Respond / not respond and I upload program to PLC. After upload program to PLC and restart it was impossible to connect again. I Have ping between PLC and PC, but could't write program. Always writes me Error <ES:0180840b> So to disable Security Option you should to do : 1. Open Works3 2. New Project (Choose your PLC - FX5U) 3. Online menu 4. Specify Destination Communication 5. Click twice in PLC module 6. Set Connect via hub (In my case i connect PC and PLC directly !) 7. Choose IP Address ( in my project : , PC must be in same network 192.168.3.X) 8. Give OK 9. Connect Test. With steps I disable security options and it was enable to connect to PLC and Write data on it. I Hope that will help to other with same problem.

  11. Hello all  i'm looking for some software to record a 100 plus channels maybe with an ascii string from a PLC? i want to be able to assign each channel with a unit and a range, flagging feature would be nice.  - selecting the channels i want to view  - auto start recording - save file and start new automatically  -view and create reports  preferably no additional hardware because of the amount of channels. this is to record an operators every move so in events of damage or plant failure we can quickly identify the problem (point the finger)  many thanks dan
  12. FX-3G MODBUS

  13. Hi, New to the site,  seeking help with an Inkjet Coder that the company I work for recently purchased. A customer is wanting us to have the printer message selection automated, because parts got out with the wrong print on them. We purchased a Linx 5900 and want to use the serial port on a slc 5/03 to send a command to select the message based on a selector switch's position. I've been pretty desperate trying to find help with this issue, because this is my first time messing with a printer. I've got the AWA instruction set up and it will send a string, but I'm not sure what to have in the string or if I have everything configured right. I've attached the program for you guys to look through, the AWA instructions are at the end of LAD 13. I'm using the serial port to make changes to the program then hooking it into the printer to try the changes out so its a bit frustrating, but I don't have a pc with windows xp sp2 so using the DH485 port is not an option. Any help will be greatly appreciated.   CNTRPUSH_4_2017.RSS
  14. 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
  15. 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 
  16. 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
  17. 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.*&lang=en&hl=en&sort=date:D:L:d1&wc=200&wc_mc=1&ud=1&filter=0&q=ASCII   62119.exe
  18. 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. 
  19. 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?
  20. 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
  21. 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

  23. 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    
  24. 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.    
  25. 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
