  2. 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?

  7. Hello, I am new to the connected components workbench software. I am working with an AB panelview component Hmi and would like to create numeric buttons to load integers into user variables in a schnieder LMD servo motor. The motor uses Modbus TCP to communicate. It appears that if I click on the numeric buttons properties there is a "Write Tag" of which you can use some default tags or create a new one. I am assuming that I need to create a new one with the motor's addressing but I'm not quite sure how to accomplish this. Any help would be much appreciated!!! Thanks, Steve   
  8. Converting DI to Ascii code

    Dear experts, i'm in learning curve to understanding converting DI to Ascii code. i'm attach here my solution that i'm think should be no problem. may i'm know how to send special symbol plc to printer. communication using modbus TCP. Printer format was: JDU |HEAD1|HEAD2|HEAD3|HEAD4| <CR>  
  9. FX3U-ENET and Modbus

    Hi There i have heard from our local mitsubishi dealer, that there is a Fx3U-ENET module which also supports Modbus TCP. so i ordered one, because i am planning to do a Project using a atv71 FU and a Codesys PLC, so the plan is, that these 3 Devices are able to communicate together over Modbus. has anyone done something similar before? what do i need to setup in FX-Configurator EN, and how can i send modbus commands through that module. i am using GX-Works 2 and have a Structured project. any help would be appreciated. thank you jason
  10. hai, im newbie in PLC, anyone can help me to connect PLC LS, expansion XBL c41a to servo L7S through modbus protocol? thanx and best regard
  11. 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.
  12. 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.
  13. How To Implement Modbus TCP Protocol Using VBA with Excel We will use Visual Basic for Applications (VBA) to communicate to a PLC using Modbus TCP protocol. Reading ten registers in the PLC and displaying a bar graph in Excel. Previously we have used VB6 to communicate Modbus TCP. The following steps will be done:1.Explain Modbus TCP protocol2.Install OstroSoft Winsock Component– Winsock API Calls for communication on network3.Develop the Excel and VBA application (Microsoft Excel 2010)4.Communicate to the PLC and sample code (Do-More Simulator)Read the rest of the post...

  14. 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
  15. Hi, i am start a aplication whith modbus for a simple comunication(read/write), some analogic imputs and outputs, whith, AB Micrologix 1500 LSP (1 com port Rs232) and whith a Omron PLC CP1L-L + CIF01 (rs232). I using CP1L like a master, but i try a lot of time and no read/ Write happens, just the recognition of Node (1) and the error code 88, no mather whith Function code i use. I use Modscan32 whith Micrologix 1500 and works fine, com settings are right to, i try 38k, 19,2k, and now 9,2k None stop bit 1, setting on CP1L are in serial Gateway. If i take the cable the reponse memory go to zero, so the communication is happen, just dont in right way. Is possible to use, RS232 whith CP1L, for Modbus communication right ? I already see PCMR code for modbus, but is to complex, for my aplication. No ofense. Someone can help me?

  18. Serie L and Modbus TCP

    Hi, We have to use a modbus tcp in orden to configurate several festo motor controllers via modbus tcp, We are going to use an L02P CPU because mitsubishi says modbus tcp protocol is implemented in its ethernet port. With FX3u we can use the function ADPRW, Is there any special function in serie L por modbus tpc? thanks in advance. pd: Any experience with MODBUS TCP with a GOT14?
  19. Good day I have a scenario where I need to connect to Ethernet ST-lite units to an L-series PLC. With a Q-series you will use the Modbus card and create a Intellgent Function Module to do this and specify the header addressing for the unit. With the L-series, you have Modbus on the build-in Ethernet port, but how do I now setup and specify the addressing for the for the ST-lite unit? Please help...
  20. On Ethernet/Modbus-TCP, if a device is a Master, can it get polled by another Master? i.e. Can it act as a slave as well. Thanks, Arun
  21. Is possible to comunicate an Eaton/Cutler Hammer INCOM/IMPACC network with a Modbus network ? Any experience ? Many thanks in advance.
  22. http://accautomation.ca/now-you-can-have-robust-data-logging-for-free-part-1/ YouTube overview: https://www.youtube.com/watch?v=6Xa2HYVOxE0 Robust PLC Data LoggerWith traditional loggers, software will read the memory of the PLC and store in a local computer. If the network stops or the PLC communication fails then the logging will stop.Creating a robust PLC data logger allows the communication to be stopped for a period of time without losing any of the data for collection. This is accomplished by storing the data locally on the PLC until communication is restored. All of the data is then read without loss. The amount of time that the connection can be lost will be dependent on the memory size of the PLC and the frequency of the data collected.This series will walk you through the steps to create and implement a robust PLC data logger using the following equipment and hardware.

    There are two Proficy ME projects in the zip file one for VersaMax and one setup for 90-30 CPU364 but is the same for all of the 90-30 processors, but read the Manual GFK-2220 to get the correct port information for your CPU and configuration. They are both working and well documented. They were done quite a while ago but I do not recall what version of PME is needed to open them. It is my recommendation that we all use the latest version. Good luck and have fun with it. R~ <))>(
