We are upgrading our A900 GOTs (finally) and I'm looking into updating our key switches to rfid readers. Does anyone know of a good rs232 rfid reader to pair with a GS2107 GOT Simple? Also if anyone has had luck with scripting for security levels and could post a sample (be it GOT1000/2000) it would be awesome sauce.

Can I write modbus rtu over RS-232 interface of the CPU module Q01UCPU
JohnStudio posted a topic in Mitsubishi
Hi, First as i know we can communication in MODBUS RTU as summary below 1.FX series, FX3U-485ADP-MB + ADPRW instruction 2.Q series, QJ71C24 <Serial interface module>+ Pre-defined protocol 3.Q series, QJ71MB91<Modbus interface module Three thing upper, i think it will ok The question is 1> FX series, Cloud we use < Serial communication only not Modbus adapter> + RS instruction to do Modbus and How to do that. 2>Can I write modbus rtu over RS-232 interface of the CPU module Q01UCPU and how -
Hello every one. I have three FX3U plc needed to be communicate over a wireless network. I'm using serial adapter FX3U-485ADP. I got E-byte data trans reciver E-30 for wireless communication. Now need help to setup the whole thing. Previously the PLC's serial connectors were connected through a flexible bus but when the platforms are running fast there is interruption in the communication. So we want those PLC's to be connected over wifi. Thanks in Advance

Here is a link to a thread on a recent post showing how to communicate serially to an Omron PLC using VB.Net. This uses the Omron Host Link serial protocols. (C-Mode Commands) It will read 10 DM registers and display them on the form. http://accautomation.ca/implementing-the-omron-host-link-protocol-vb-net/ Here is the source program that can be downloaded.

Hi, I have a self-bought usb-serial cable converter for CP1E. Currently can't connect to my PLC using PC. CX-One says "Failed to the PLC". I am supposedly to use "SYSMAC WAY" as my Network Type in PLC settings? EDIT: The CPU type is N30 I've checked the following settings: 1) COM number is correct ( as checked from windows Device Manager side) 2) Cable driver is installed, there is no "unknown" driver in my windows Device Manager 3) My RS232C LED in PLC is not lighted up. Any other suggestions to check settings ive missed out would help, other than buying a new cable for the moment. Regards, Summerstone

Hello, PLC: NX1P Comm module: NX-CIF105 I am running a serial (RS485) network to control several motors. As a trigger for to read the serial port I am using the ( Ch1 Receive Data Exist) bit, which is an internal bit that's ideally should be energized when there's data in the Receive buffer. However, this bit isn't reliable at all. I am reaching out today to figure out if there's another way to trigger the receive command ( preferably without a delay) thank you all Cheers!

I recently purchased the SIEMENS CONNECTION KIT (6ES6400-1PC00-0AA0) with its corresponding serial cable to connect to a MICROMASTER 440. I connect my RS232-USB cable to the serial cable. But I can not connect in any way! What do I do wrong? 1. In the micromaster 440 I put the following USS configuration parameters (USS = serial communication): p2010 = 6 p2011 = 0 p2012 = 2 p2013 = 127 2. I put the DIP of the Connection Kit (Ref. 6ES6400-1PC00-0AA0) 1 ON, 2 OFF, as indicated in the manual. I connect the connection kit module with its serial cable to my RS232-USB cable. And I connect the USB to my PC. 3. Open "Set PG / PC interface" and select PC COM-Port.USS.1 4. I go to the properties and I am selected COM1 without problems. 5. But I do the transmission speed test and can not find anything. 6. Also in the diagnosis of PC COM-Port.USS.1 I do the test and can not find anything. Supposedly my RS232 cable is correct (I have tried several tests). And the configuration of the COM port in "device manager" also looks correct. What am I doing wrong?? Zhanks!

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!

Hello All, What are the methods to get the monitoring data from A series PLC? I know its not supported any more, interface modules are not available..., So the basically, If I want to write customer software (may be embedded) what is the protocol I need to follow? I am connected to CPU unit by the way, there is no other modules except few digital and analog interfaces on PLC. Thank you in advance for your direction, direction in any way would help!

Morning Guys, For my latest project I need to read a gas sensor via 485 from a Momentum PLC. I've been through the help files, but they seem to only raise more questions than they answer, they only seem to reference PLC -> PLC comms. I've had a play with the 'MBP_MSTR' & 'OUT_IN_MBUS' function blocks, but i can't seem to get anywhere, Has anyone got any examples of reading in data via 485, or can anyone lead me in the right direction?

My issue is trying to receive data from a Datalogic PM9500 barcode scanner onto a Siemens ET200S (IM151-8 PN/DP) CPU using a serial interface card (6ES7 131-4BD01-0AB0) with the ASCII Protocol. The software that I'm using to program the PLC is TIA Portal V14. I made use of the built-in function block S_RCV to try and receive the data into a data block that I have created. I connected the Datalogic's base charger unit directly into the PLC's SI module. (I cut the DB9 plug off) So, Pin 5 (RXD) of the SI module is connected to the Tx wire (Brown) of the scanner, the Tx is also connected, as well as the ground, to the SI module, however, I only require the Rx. There is no flow control. Upon scanning a barcode, the Rx LED on the SI card flashes, indicating that something was received. I have tested the scanner using a terminal program called "Hercules", and I am receiving what I should be when I scan something. The parameters such as Parity, Stop Bits, and Baud Rate, etc, of the scanner corresponds to that of the SI module as well. I paramatized the S_RCV block as follows: 1.) EN_R is always ON. 2.) R is defaulted to the instance DB that was created with the function block's tag. 3.) LADDR is set to "100" as that is the start address of my SI Module as defined in the device configuration. 4.) DB_NO is set to "2" as it is the number of the data block I created for storing the received data. 5.) DBB_NO is set to "0", which I understand to be the data blocks offset start point from where to start inputting the data. The rest of the NDR, ERROR, LEN, and STATUS outputs of the function block are also defaulted to the instance DB tags. I only want to see if I'm receiving the data from the barcode scanner into the datablock. I created an array of bytes and I also tried with characters from 0 to 30 to store the data. As I mentioned, the problem comes when I'm trying to scan something, the RX LED on the SI module pulses, but when I monitor for any changes in the Function Block, as well as for any changes in the Datablock itself, nothing happens at all. I don't know what If I'm missing something, this has been bugging me for some time now, I'm quite new to the whole programming scene, I would appreciate any help I could, get also I've attached the project file too. =) Yumi_Panel.zap14

hello, Maybe somebody know how need send only hex numbers via rs232 in the external device? I tried to use SEND_RECV_MSG function block, but unsuccessful, because send ASCII code. Need send 16#AE number, but I don't have any idea how need do it. I am waiting your advice. -
Hey guys I don't have much experience in PLC serial communication and I'm tasked to integrate 6 OP-905 scales with our EATON based control system. The scales are rs485 asynchronous serial communication, my concern is that if the device is not designed to be an RTU then I cannot use modbus. And if that is the case how do I talk to multiple scales using the async protocol. Has anyone done this in a similar platform?
