  1. Hi! I'm new to this forum so please be patient with me. I'm trying to automate a cable cutter that uses Unitronix M90. I want it to load a certain length and quantity when I scan a barcode. Have any of you sirs connected M90's RS232 to the serial of Raspberry Pi? Is there a set of code to send to the M90 for it to be able to communicate? Sorry the machine is always running and I need data before I can try and test.
  2. I am trying to receive data from an instrument. The data stream is a series of binary numbers. The help file for the Protocol FB says that it can receive a variable as a binary number. However, in practice this does not seem to be the case. Can a V700 PLC receive a binary number and save it into an MI ? again using the protocol scan function I do not see how this is possible. Thanks for any help with this. Bill
  3. Hi! I have a communication developed with v230, v350... With visiologic, And now i have to do the same applications but in Unilogic environment, but i'm experiencing some dificult by the new plataform and new tools, theese applicatins was maded to "send and receive" messages through Rs232, to send messages i already have "some sucess", but it's not working to receive msg, i need to receive and shows the value received at the hmi in a decimal format, visiologic com_ok_2019 - Copy.vlp RS232_SEND_PROTOCOL_MULTIPLE_WORKING_RS232 - Copy.ulpr If anyone could help me I aprecciate a lot
  4. Im having issues with getting communication from a Unistream 7 to a syringe pump through a usb to RS232 cable. I am trying to use the message composer to send commands over but have not been successful. The brand of pump I am using is Chemyx (https://www.chemyx.com/support/knowledge-base/programming-and-computer-control/serial-rs232-commands/) The cable is good as I can take that same cable, connect to a PC, connect thru putty thru its COM port, and type commands without an issue. I enabled "USB for Serial Communication" under the PLC communication tab only changing the Baud rate t
  5. Hi all, I want to use a V700 and a device which also use RS232 connection protocol. There are some datas that should be read and controlling of ON/OFF status of the device. However, this will be the first time that I will use RS232 communication. How can I program this? For example, there is a command that I need to use below. I need to read those values and seperate the temperatures to different MI's. I believe I succeed to initialise communication port but not really sure. $TEA: Read all temperatures Command with checksum and carriage return = $TEAA4B9<cr> Resp
  6. I have multiple devices such as printers(2) and scanners(2) that I want to communicate to using only 1 COM port in V1040 PLC. Printers and scanners support RS232/RS485 protocols. Can someone suggest on how can I achieve this? I looked at options with Modbus protocols, but I didn't understand how can I assign network id's to my printers and scanners. If I am required to have any additional hardware, please suggest.
  7. Hi. I have a Unitronics JZ20-R16 (Jazz2) controller I’ve programmed to run a simple air ventilation system in my house (The thing is running great btw.). I also have a self made Arduino based data logger (I use it to monitor and log my energy consumption, temperature, etc.) I’m not building those things or mass producing, Arduino electronics is my hobby - I just use it to stay sharp. So I decided to cross-integrate my air vent. Controller with my data logging unit (I want to see the status of my air vent. Controller unit on Arduino). So for starters the task is to simply send a 16b
  8. Good morning. I am trying to print messages using the send protocol from a Vision120 to an epson lx350 dot matrix printer. I have the Com Init command and the protocol config command setup. I have it wired up correctly (I believe) from the RJ11 to RJ45 to the DB25 adapter to plug into the printer. This system has worked in the past, I inherited the project from a customer who's controls engineer left, and now I'm stuck on getting the printer to work. I have downloaded the program and HMI config and they are working fine. Does anyone have experience in something similar to this?
  9. Hi All - I am working to connect a barcode reader to a Vision 120 PLC via RS232. I have two barcode readers on hand - a Motorola Symbol LS4278 (which reads 1D and 2D codes), and a 1D-only Royal PS700-LSR. Both readers are set up the same way - serial cable with external power input into the scanner, connected to the PLC by a DB9 to RJ45 adapter. When connected to a Serial-to-USB converter to the computer, both scanners send the same data to the Serial Terminal (I am using Hercules). But when connected to the PLC, the Royal scanner data is read as expected, but nothing happens when sc
  10. Hi! How to change Unistream UAC-01RS2 module RS232 serial port communication parameters within ladder function? Connected serial device (Kamstrup Multical M66 type energy meter) use different baudrate for Rx and Tx communication. I need to swap Unistream serial port baudrate between 300 for Rx and 1200 for Tx to get data from energy meter. Also Unilogic serial port configuration allow minimum baudrate only 1200, but there is a need for 300! In Visilogic it is simple, there is a "COM Init" function block for this purpose, that i can use within ladder. How to resolve it within Unilogic l
  11. Good Morning I have not written my program yet, but I want to be able to communicate a string from my new Unistream to a RS232 device, in fact a Hitachi Printer I have successfully done this with a Vision PLC, but now all of my inbuilt FB's have gone with Unistream, and I am struggling I have added a Com device to the unit, and configured it ( I think) I cannot see however to set the pre amble and post amble for my strings what I want to do is On the HMI have a string called lot and another string called Julian Date I then want to be able to send those
  12. update: 12-10-16 I take that back, I failed after two weeks of trying every conceivable configuration to implement a complete working model of serial MODBUS with read holding register and write coils exchanges to four vision slaves over RS232 radio modems. Has anyone out here successfully setup a Unistream master to a Vision slave, serial, 232 over modems (RF), read registers (more than one) and write coils; without errors? For example sequentially reading five 16 bit integers and in next line of periodic slave table writing a 10 bit array of coils (or a single 16 bit write regist
  13. Hi, I 'm new to samba and Visulogic programming, and I'm having some problems to use the samba sm35-j-t20 serial port to send data into a chinese printer(csn-a2-r), it uses rs232... I initialize the the com with the printer parameters and I configured an protocol, but when I try to send the messages something goes wrong, The data is not sed correctly, it appears ramdom stuff in the printer. obs.: the printer is 12vdc so I hacked it with a lm7812 to be able to use it with the same power supply. Someone have done something similar and/or can help please?
  14. Hi I have two old units but i haven't got original cable. I dont know if they work good so i tried to connect to them with my pl2303 rs232 to USB converter and an rj11 cable. Tried it on Windows 8.1 64bit and Windows 7 64bit. Evertime it say that it can't synchronise with PLC. I use proper COM and got good drivers and good settings.
  15. Hi everybody, Greetings to all, another newbie here... Having some issues on getting Modbus RTU messages to work on JAZZ PLC. My setup: 1) JZ20-R16 PLC with MJ20-PRG adapter (?) plugged in it. I'm using MJ20-CB200 cable (RJ11 plugs on both ends) and MJ10--22-CS10 adaptor (DB9 female connector). Using this gear I can query the PLC with modbus RTU messages over RS232 serial line. Serial line settings I use: 9600bps, 8(data bits), none(parity), 1(stop bits) 2) Gemalto modem (BGS5T) as a modbus master. It has DB9 female connector on it as well. 3) Serial to USB converter c
  16. When I connect TC35i modem to PC via USB-to-RS232 converter everything works greate. Doing "Prepare PLC-side modem" in Modem Services in VisiLogic OPLC IDE result in connection and success. Making a test dial from Modem Services also results in success. But when I connect my PLC (it is V560) with the modem using a 4-wire RJ11 programming cable (ended with MJ10-22-CS25 and simple Male-to-Male adapter) then the Modem Init fails and SB 83 bit become 1 (SB 83 is Modem Init Fail for COM 2). I suppose that something wrong is with the cable. How am I supposed to connect V560 to TC35i? Tha
  17. Am using Red Lion display, model PAX2D, with an option card for RS232, and want use Modbus RTU to display values from a V350. I can get successful comm. by connecting RXD from display to RXD(pin 3) on V350, and TXD to TXD(pin 4) with no ground. As soon as common (pins 2 or 5 on V350) are connected to RS232 common on display, comm. halts. By wiring as above, I can read values from registers in the display, but they seem to be random numbers, not anywhere close to what they should be. For instance when reading register 40483(display baud rate), a value of 8960 is returned no matter wh
  18. Good Morning, This has driven me to drink, well it seemed like a good excuse! I am trying to connect a Microscan HS-1 Barcode scanner through RS232 to Com Port 2 of a V120 PLC From what I can see I have everything set right, but when I trigger the hand held scanner the information that I have scanned does not appear to be sent to the PLC I have all my Baud rates, pre ambles and post ambles set right in the scanner, I feel if I have everything right, but I just cant get the flow of information. I have attached the program and am looking for someone brighter than me to see where my dumb
  19. Good evening I have written a program for a barcode scanner that reads a barcode and parses the info to the screen, and then communicates it to a printer I do however have a couple of issues 1) If I plug the scanner into the port of the V120 it doesnt work, however I think that must just be me, as I downloaded a program called termite and plugged in the PLC to one port and the scanner to another, set my ports to forward in the program from the scanner to the PLC and it works. The major problems that I am facing is that unless I switch screens the HMI does not update, cant work out how t
  20. Hello, I have a .net application that connects to a 570 via RS-232 using System.IO.Ports.SerialPort. Normally, it will connect. However, when playing with different baud rates, it sometimes does not connect until I connect the same PC with any Unitronics software (Visilogic or Remote Operator). My question is this: With VIsilogic, it appears that you can define the baud rate to anything in the connection properties and it always connects. How does the controller adapt accordingly? I think "out of the box", the rate is set to 115200. If I change my application to 57600, it failes to
