  1. Hi all,I'm completely new to ASCII and trying to figure out where I'm going wrong here.Application: I need to send 2d barcode data to a KGK Jet model CCS3000L Inkjet printer. Only protocol possibility is ASCII. PLC I have is a Micro850, and the only port option for ASCII is the serial port. I modified one end of a 2707-NC11 cable to connect PLC TxD to printer RxD, PLC RxD to Printer TxD, and PLC SG to Printer SG. I jumpered CTS and RTS at the printer connector, and the 2707 cable I'm using doesn't have wires on the Micro850 CTS or RTS pins.Printer company verified that I can just jumper RTS and CTS on their side and not connect their DTR and DSR pins (since I'm not using hardware handshaking). I don't really need any flow control for the application ( I don't think...again, ASCII noob here).Do the CTS and RTS on the PLC side need to be jumpered? Does the DCD pin need to be jumpered or connected to something if I'm not using handshaking?I downloaded the Micro800 ASCII read and write functions and function blocks from Rockwell library, and they seem to be working, except that I keep getting ABL error id "7". This error states, "Cannot complete ASCII send or receive because channel configuration has been shut down using the channel configuration dialog box." I have the serial port enabled and configured to ASCII, no handshaking, baud 9600 same as printer, no parity check, 1 stop bit, character length of 8.Any help in pointing out what I'm doing wrong or things to try would be greatly appreciated!   ASCII_TEST.ccwsln
  2. Hi guys I have an control logix plc im looking for a module which is the same as 1769-ascii module. I know that module is for compact logix. Unfortunately i didnt find a good one for that purpose.  Anybody can help with that ? Thanks ahead.         
  3. Sorry new to working with PLC's,  I am trying to write text to a ST file on an RSLOGIX 500 machine, its for a LED display, I am just trying to update the screen to new texts, it all works I am just having trouble inputting the text properly into the string file. I would like to read about it if anyone can point me to a good document or manual that can explain what characters to use?  I see many posts about using VBA using Excel work on RSLOGIX 500? But would like to know how to do it manually first.  Thank you

  5. Hello people! I'm using a NX1P2 controller combined with a CIF105 serial card installed on it. For my project, I get some data that are in ASCII form and I want to keep that form when are extracted in a .csv file. I have established the communication for getting the data but, the problem is that I cannot extract the data in the ASCII form. Data extraction comes in Hex form. I use the NX_SerialRcv instruction for the communication and the AryToString conversion for the data. When using the Watch Tab Page I can display the data in ASCII form but, as far as I understand, this is only for online monitoring. I went through topics here and OMRON manuals for finding any Hex to ASCII conversion instruction but the only info I came across was for CX controllers which cannot be implemented to NX controller. Is there any similar instruction for NX controller or I should create a new Library for the conversion? Any tips and/or a sample would be highly appreciated! Thanks! Man31    
  6. Now I working on omron CP1H PLC, i'm receiving ASCII number from another PLC which is something like this  "#3031 #3030 #3030 #3030" which mean 01000000. How to convert the ascii number to real number or bcd without separate them? I know how to convert them which is using HEX but its turn out the number will separate into this 0100  and 0000.

  8. I am working on project where I need to program delta PLC to receive ASCII code from scanner. I anyone know how to program it helpls me alot.
  9. Hello all, I am working on a project where I am communicating with a Mensor CPT6100 pressure transducer using a Micro-850 PLC. For this, I have used an AWA instruction to write some ASCII characters to the sensor. The sensor then responds to the write instruction by sending ASCII characters to the RX buffer and I used ACB and ARD instructions to read the ASCII characters. Now, I have set the ACB trigger type to 0 (msg triggered only once) and it successfully reads from the sensor. However, when I set the ACB trigger type to 1 (msg triggered multiple times), I do not get any reading in the ARD block. As a matter of fact, the ACB Q bit switches off every time the program is executed when the trigger type is set to 1. I am trying to get continuous readings from the sensor, but when the trigger type is set to 0, the program latches on to the first and only reading and it won't change. My question is, how can I change my program so that it can continuously and autonomously read from the sensor without me having to manually trigger the AWA and ACB instructions every time. I am attaching the program to this thread for your reference.  ASCII_Test_Copy.ccwarc
  10. Hi guys, so i'm trying to send data to plc omron cp2e-n40dra via RS232C, I use RXD and TXD but it looks like my programs are wrong, the indicator of RS232C are on everytime i send the data so it looks like PLC receive my data but when i see it in memory PLC D i can't find any data stored. Can anyone help me please? I attach my Gdrive for pictures since i can't upload pictures in here *The data that i sent is in ASCII https://drive.google.com/drive/folders/1GPXa1U1PLMU2WKmo4YRPe32wHHyVCGUv?usp=sharing
  11. I have been working on a PLC project that requires sending ASCII commands/queries to an external pressure transducer using the Micro 850 PLC (2080-SERIALISOL module) via serial port communication (ASCII protocol) and in response the PLC would read pressure readings from the transducer. I was able to write a ladder logic program that reads ASCII code from the transducer and converts it into string and inversely converts string output from the computer to ASCII and sends it to the transducer. However, I am uncertain as to how I should send the command string from my computer so that the external transducer receives it, recognizes it after the <cr><lf> is encountered and sends a pressure reading. Any suggestions as to how I can type in commands from my computer and receive responses from the transducer?
  12. I have a function that reads ASCII code from a transducer, converts the code into characters and places the characters from the serial buffer into a string. Now, I am trying to convert the value in the string into a 64-bit float number. Any ideas on how to do that on the CCW?

  19. I am new at PLC programming, I have tried some ways to convert a text into DINT and I haven't found the right way yet, maybe somebody can help me. I want to convert "Hello" to DINT, for example. I tried converting it on here  https://www.branah.com/ascii-converter  to decimal and then using it as an input for a ROUND, FLOOR, TRUNC blocks to get a DINT, but when I get the result and use as an input in a DI_R i block the output doesn't match with the first conversion of "Hello". Any tips on how do I get it to work, please? Thanks in advance.

  21. Hello All,                 I am in the process of installing a DPM Scanner to one of our machines.  I am trying to program an ASCII String Compare to compare the scanned part number, stored in a string as ST14:0, to a constant value stored in ST15:13.  I have used this tactic before in other applications and it has worked fine every time, except this time.  Am I doing something wrong?  Is there a setting I am not aware of?  Please see the attached image.  Thanks in advance!    
  22. Hi all, I have a micrologix 1400 plc and an SIC E10 engraving machine. the engraver requires its marking info ( day/year/random sequential number etc) to be sent to it via rs232 connection. the manuals have nearly melted my brain and I have no clue how to convert and send this type of info via rs232. please help.   thanks       NOTPROTOE10V6US-R04.pdf
  23. 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,
