Twincat 2 with Motion control (Maxon motor) and torque sensor
TwinCAT Newbie posted a topic in Other PLCs
Hi, I'm new to TwinCAT 2 and i'm upgrading a long time design (hence the TwinCAT 2 reference), to read a more sensitive torque signal. I'm using a Beckhoff CX1030 as my PLC Controller. I needed to add 'homing' to my motor sequence and confirmed with Maxon, im using the function blocks correctly and in the correct sequence to establish my 'absolute zero'/'home' position. The motor has an output to write to: ControlWord, which tells the motor that the position it is sitting in is '0.' My program compiles, it runs, it writes each function block, but it's not seeming to get back to the test run opMode, even though i tell it to and the function block performs the 'Write' function. it's stuck at zero and not reading an analog input signal from my torque sensor. so im getting an artificial torque reading through every test. i think this is related to my tare motion. I start the program, home the motor, get into profile velocity mode, tare my sensor, enter profile position mode, go back to position 0, then back to profile velocity mode, run a test, sample data, go back to 'home' or '0.' I wonder 1st, is my variable not linked properly through the system manager? 2nd, i set a boolean variable to set the 4th bit to 1 in my control word write (setting the 4th bit high will set my current position to absolute zero), but did i not connect the program to the main sequence properly? looking to read a valid signal again and see that my motor moves back to 'home' each time. Do i not need to home the motor after the tare, since the tare nulls out the torque value after the tare? after this i need to program my sample period, instead of it being fixed, as it is currently written and then use my home position as my trigger to start sampling.... Beckhoff applications department is overloaded, currently and can't help and this is all beyond the knowledge of the general support line. I've gotten fairly far, on my own, but of course, the project is under a time crunch. Does anyone know twincat well enough to help guide me? -
I currently have certain amount of Recipe data located in form of Excel file on to a PC with static IP address. Is there a way to get that data inside the Nj501 without using an SQL server as I currently have NJ501-1300 which doesn't support SQL. I am okay to send data to the SD card I currently have on NJ PLC as it is easy to get data from SD card to the NJ501. If there is any example code or a link that helps me create i would be helpful. Thanks in advance. FYI: I am currently using NB10 HMI with NJ PLC.

Hi all, My Task: To control write to registers to my MSI430 safety PLC from Leuze Electronic using a HMI as a master. Protocol: Modbus TCP MSI430 (Modbus TCP - server/slave) Generic HMI (Modbus TCP - client/master) I'm reading Okay from the Register address 401101-40110 But I'm not able to write to the MSI PLC to address 402101-402109 Please see the attached images for gateway description for the device. Please advice/guide on how this could be done. I have tried using MBPoll and it says Illegal Data Address. Kind Regards NarkO Please find the below link for the manual

Hello everyone, I am working with a NB10W HMI connected to a PLC NJ by Ethernet protocol, I would like to know where to start regarding the sending of data from the PLC to the HMI. I have a 50x15 array and should show all those values in the HMI for read / write. How to proceed? I started working with PLC for a while. I'm using Sysmac Studio to programm the PLC and NB designer to the HMI.

Hello everyone, I need the help to do setting of datalink between CJ2 and LOGIX-5324ER. The Allen bradley PLC was programmed by contractor and I have no software of it, so I am doing the network setting in CX-one network configurator. I tried to do the instruction in the Quick Start Guides on Downloads section here under Omron, but I couldn't find the option to register tags in network configurator. Is there anything wrong here? or is it possibly because of that they not support to do a datalink in these version of PLCs? They appeared like these in the pictures.

Hello, I'm trying to make communication between a 315-2 PN/DP and MSA Gasgard XL. I want to read out 40010, and 40020 from GasGard, it works sometimes, but most of time the connection does'nt build up. The parameters i using are: Start address: 9 Lenght: 10 Recv_Time: 5s Conn_Time: 5S I did playing with Recv and Conn Time and it effected the rate of succesful connections, but it still drops too often. Also i tried to read only 9 and 19, but then it didn't read 19. Anyone knows how could i optimize the connection? Thanks

I'm looking at project with an OMRON NJ-101. I was planning on using Modbus TCP/IP from the PLC to talk to a MOXA gateway (MB3170) which would then talk to about 7 different slaves over RS-485. Looking at detail at the blocks that are supplied by OMRON (MTCP_NJ V1.3, available from https://www.myomron.com/index.php?action=kb&article=1245), I noticed that it doesn't send the slave ID, which will mean that it won't be able to talk to different slave ids through the one IP Address. I had a look through the actual code and it sends "FF" in place of the slave id. In particular I was looking at the "MTCP_Client_Fn03" block. Is there another way to get the NJ101 to talk the full MODBUS TCP/IP protocol? Is it possible to edit the blocks provided by OMRON? It seems to me that they are locked down. If I could edit it I could just add the functionality Thanks for your help in advance.

PROFACE HMI AND SIEMENS TRANSMITTER
0608jai1990 posted a topic in Modicon / Telemecanique / Schneider Electric
Greetings everyone, I have a Proface HMI(LT-4201TM Modular type DIO) connected to a siemens flow transmitter(MAG6000). Communication between these two devices is using modbus. The modbus register that im using to get the data/reading of a totalizer from siemens transmitter are 403022 and 403023. I managed to display the exact totalizer value from siemens transmitter on the Proface HMI screen. But I couldnt get the exact totalizer value at the ladder logic side, the value that i get at the ladder logic side seems like a raw value. For an example, the totalizer's value is 147083(real value), but at the ladder logic side the value for 403022=15598 and 403023=17316. Can anyone guide me to solve this issue. Thanks in advance. -
hallo, i have problem here. i want to connect HMI OMRON NB7W-TW00B to weighing indicator with Modbus RTU rs485. i use this link https://www.myomron.com/index.php?action=kb&article=1538 for wiring diagram for rs485. and the baudrate, databit, parity check and stop bit is same between HMI and weighing indicator. but the output in HMI is "[2] PLC No Response: 00-01-2" i think the problem is my rs485 connection. can you help me? thank you.

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?

Hello, I wanna be sure before I'll spend some money, will I be able to control Turck devices (ie http://pdb2.turck.de/cz/DE/products/000000170000c8000003003a ), from I've found here on forum and on internet it looks to me like it should be possible, but I'm new in field of automatization. Thanks in advance EDIT: I'm talking about Modbus

I am connecting a WeinTek eMT3105P to a CompactLogix L2 series PLC via the WeinTek Rockwell PLC (CompactLogix) - Free Tags driver and I cannot for the life of me get the thing to connect. I have all my tags imported and have played around with all the settings in the manuals I can find. Any help/advice would be greatly appreciated. I know my IP addresses are correct and if I connect my cable directly from the HMI to the PLC I still get the "PLC no response" message

Hello everyone. I got the project where plc Q00UJCPU with the module QJ71MB91 connected to the slave device via 485 channel . This plc takes some values (like current/voltage etc). i dont have access to this plc cause he is on guarantee on another service company. So question is... How to connect to this device as a other plc FX3U via 485ADP-MB (and i think RS command) module in parralel to QPLC already working link? Is this possible without harm QPLC and all the data which he takes?

Hi everyone, I'm trying to use the cam control data by using an MR-J4-A-RJ and MR Configurator 2. When I switch the input "CAMC" to ON, I see that the output "CAMS" is switched to ON which means that the cam mode is activated. When I switch CI0 to ON to choose the Cam Data No.1 and switch ST1 to ON...nothing is happening like if there is no Cam Data. Please, have you any issue or idea ?? Thank you in advance Omar

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?

I am developing an application with fx5u with inverter d700, it fails to send a command to the inverter, only running the application and monitoring the clp does not appear to fail, only when it sends a command. Attached photo of plc configuration and error. Do you have any secrets to doing communication, can I do it with a normal network cable? I'm doing with just one inverter, as the terminator should be at 110 or 330 ohm.

I need some help with G.input and g.output commands. I have a Q04UDEHCPU and my slots are as follow: slot 0 - QJ61BT11N cclink slot 1 - QJ61BT11N cclink slot 2 - QJ71C24N-R4 2-channel RS4222/RS485 I need to have 2 separate RS485 stings going to different devices. I cannot find the way of setting up the g.output command. G.Output "Un" (s1) (s2) (d) "Un" says it is the start I/O signal of the module, but I am not sure what that means. What there be a different "Un" number for each channel?

CompactLogix PLC Family 5370 Data Byte Order
Muhammad Azeem posted a topic in Allen Bradley / Rockwell Automation
Hi, I am working on a project in Digi Module ConnectME9210 and sending data to Allen Bradley PLC (CompactLogix 5370 family). I am not sure which endian I should use to send data. Does Allen Bradley receive Data in Big Endian or Little Endian? I have another question as well. Can I make an EDS file to tell the PLC to receive data in UINT16, not as a single byte?
