  1. I want to communicate my Q series PLC with Factory IO using GX works 2 software, I want to use modbus tcp/ip as server in factory IO and the ips are as follows plc CPU: 192.168.1.30 modbus:192.168.1.245 pc:192.168.1.240 (I have set the ipv4 settings with ip address that i wrote subnet mask:255.255.255.0 and default gateway: 192.168.1.1) local network: 192.168.1.1 I want a start stop switch as an example and a warning light so that i get to know how the communication works as it is not working currently I have done the communication through modbus tcp/ip as client but unable to do for modbus tcp/ip as server. the ladder logic code is as follows. the addresses for y80, y81 and y82 are , QY128, QY129 and QY130 I have done some settings for automatic communication parameters that are as follows   The auto refresh settings are as follows   or the factory IO i have created the following environment the settings for driver configuration is as follows Can you let me know whats the issue here as i am unable to communicate via the factory IO with the PLC . Can you guide me in any way?    
  2. Hi All, I need to start PLC Data Logging using an SD card in the CPU module for an iQ-R PLC.  I have not attempted this kind of logging before and I was wondering about any restrictions on the type of SD cards that can be used. The documentation I have found says "SD/SDHC memory card: 32Gb maximum". Does anyone know why can't I use a 64 GB SD card ? (maybe due to addressing limitations?) Also, when I look for SD cards, I see different speeds of data transfer such as 120 MB/s or 100 MB/s and I was wondering if there is any difference as far as the logging is concerned.  Does anyone know if there are any other restrictions, brands that don't work? Useful tips? Cheers    
  3. Is it possible to connect an old Beijer E300 terminal to a Mitsubishi FX5U base unit via a serial interface (RS422 or RS485)? And which protocols do I need to select?
  4. I am working on resolving issue in Press Machine where previous engineer has developed logic as per attached file. the atatched screen of HMI can only access by Engineer and only Engineer can set value of SPM (Stroke per minute). Once switch is set on the SPM of any job can not go beyond set value. The issue I am facing it when we power cycle, the switch get off and the register D2842 get SPM back to normal (set as per the die data) not by eng. How I can hold that data after Cycle power?  
  5. Hello,  I have two pressure transmitters connected to a tank. One at the top and one at the bottom. How can I calculate the level of the tank ? I know the height and Specific gravity of the materials.    Thank You  Pratik Jain
  6. I've setup an Omron NX102 PLC with two CIF105 cards communicating with about 40 MX2 VSD's (20 on each card). Generally it works pretty well. I used the attached document to set up the devices. The links on the document to the examples don't work, so I'm unsure if I missed anything. My problem is that every day, sometimes multiple times a day the communication seems to die. i.e I either loose the output to the VSD and nothing will run. Or it all runs but I loose the feedback, as in I get no running signal even though the drives are running causing a fault in my program. I'm at a bit of a loss as to what might be causing the issue. To resolve it, I put the PLC into program mode and back into run mode and everything is happy again.    Has anyone had a similar issue or offer any advise? MX2_Control_Serial.pdf
  7. Emerson (GE) memory map data types

     I've always had this Allen-Bradley memory map taped on my wall in my office. It used to be handy to use, until I remembered al of the prefix letters for each data type. Now I am using Emerson (GE) the old proficy software now called PAC ME machine edition. Now I'm finding it's about impossible to find the data type list amongst the thousands of help files, videos, ect... it seems like a simple thing to find, but I'm not having any luck. They use I and Q for regular inputs & Outputs, but there are R files, M files, S files, N files, G files, ect.... this is old-school PLC software that doesn't use tag names.   Is there a steadfast rule for each type, or can they be used for any type of data? Dazed and confused...  
  8. Hi Everyone,I have a customer that needs a CQM1H (CPU51) replaced. They purchased the processor new-old-stock from a source they found online. It arrived in the original packaging and had the safety label around the top of the unit, so it seems that it is as advertised and no need to suspect that it would have problems. I purchased secondhand, a power supply to attach to it and program it from the bench instead of in the machine. The customer also provided me with an SD card containing the project file(s) for the machine. I am able to load the project in CX-ONE (running on Win 7) just fine. My computer has a native serial port (COM1) and I built a programming cable to work with the DB9 peripheral port according to a diagram I found online.The processor powers up right away with the ERR/ALM continuously on. No other LEDs came on initially, and after a bit of playing around with communications settings, I finally landed the right protocol and my computer seemed to identify the processor correctly. I compiled the source and attempted a transfer to the PLC. I got some failed message (or maybe messages) at the end of the transfer. It did seem to send all of the binary code, it just ended with an error message that I unfortunately didn't write down or grab a screenshot.Anyway, what I have now is a PLC processor with the ERR/ALM LED on always, I've never seen it in RUN mode, and now after the programming attempt, I'm seeing the COMM LED strobing at about a .5sec frequency (with or without a cable attached to the peripheral port), AND I cannot get CX-Programmer to again acknowledge the processor anymore. I'd like to reset this back to the way it arrived to me, but can't figure out how to make that happen offline. The DIP switches don't seem to cause that effect. I should say also that the DIP switch settings are all OFF except 3 and 7.Any help is much appreciated!Thanks,John  
  9. Hi there! I've been looking for some fault codes table for the 1734-AENTR adapters, since I'd like to show a message in HMI with some information when there is a faulty adapter, but I haven't found anything on the internet. So my question is, is there any type of table like this for these adapters? Right now I have a PLC with some AENTR adapters in the program for testing, and since there is actually no adapter connected to it, I can see a 16#2024 error in the module properties, but can't seem to find that info in the module variables.   Do you guys have any clue on how to find this information in order to show it?   Thanks in advance!
  10. Hi,  I write a CAM function to sync 2 axis (Rotary & linear). i am using a virtual servo as master, and 2 physical servos as slave. The problem i facing is, with the exact same CAM profile setting, when difference speed used will give difference result of movement. Below is my setting, Master axis     linear motor move 0-180degree   0-500mm 180-360          500-0   when running with slow speed, it move following the CAM profile setting, however, when moving in fast speed, the linear motor will only move halfway then start to moving back 0 already. Has anyone encounter this issue before? is it i missed out some setting? Thanks.
  11. HI, I am trying to write a program to read the timer up to 2 seconds, then use that time to calculate the frequency per hour the machine is running. Could anybody point me in the correct direction to Read  %TMx.V & store that value.  I have done this with Omron, but do not use SoMachine Basic very much, so am a bit lost, I used 2 timers, one 20Ms to collect the number of the 2 second timer, set read reset. add the 20ms back on then do the calculation then multiply by 60, to got sheets per hour of a printing machine. It was suggested count how many over 36 seconds then multiply x100, but that is slow, mine was close enough & instant. Thank you.  
  12. Hi All, I need access to a the Safety function blocks within a safety CPU using sysmac studio on a machine we are upgrading.. Is there a generic password available to gain access? Best Regards, Paul  
  13. I am trying to connect a Panel PC (Bartec RS-422) and an Omron PLC (CJ2H RS-232) I am using a Kinematics 2199 RS232 to RS422 converter. Results: Testing software Multiway v9.5 1) Using a usb to rs-232 cable on another PC     - I am able to send and receive a hostlink commands between the panel rs-422 converter and the PC rs-232. commands come through correctly 2) Using the PC to connect to the PLC     - If I connect directly to the PLC using the usb to serial cable and a short adapter I made to map the Omron PLC pin out 2-2,3-3, 5-9, I can send and receive hostlink commands to the PLC. Everything works as expected 3) Using the Panel and the USB Cable    - If I connect the usb converter to the Panel I am also able to communicate with the PLC 4) using the RS-422 port on the Panel     - If I connect the panel RS-422 port and converter and then connect to the PLC. I can only send commands; I cannot get any responses come through from the PLC. My converter box has LEDs on the RX and TX channels and I can see the PLC tries to send something. But something must be corrupted as multiway does not show and response.  I have tried a bunch of things but I am at a loss on how to diagnose this issue. Since I can get the two PCs talking to each other sending and receiving, I can rule out any wiring issue between the converter box and Panel.  Since I can plug the USB into the Panel and get it to work correctly, I can rule out any operating system issues and PLC configuration issues. The only link I cannot verify is that from the converter box to the PLC, I am not sure if the PLC can push hostlink data that has not been requested.  I have no idea why I can write to the PLC but not read. If anyone can provide any insights, I would greatly appreciate it, It has been two days and I am stuck. I am looking at maybe getting a logic analyzer to try and see what the PLC is sending back, but that will be months away.  I am happy to try any suggestions       
  14. Hello, In GX Works2, what do asterisks before function block input and output variable names mean? Thanks,    
  15. Send data TXD548)

    Hi,   After a long time, searching for missing communication I think to have found the cause. In this CMP2A plc there is a receiving device connected to the RS-232 port. . During operation it can happen that in the same cycle there will be 2 functions to send different data.. I never receive those 2 data,  only 1 is received. I can set a delay for sending this but this seems to be 'overkill', Is there a simpler way to do this..? The 2 pics are part of the program. After putting the P_off before the other transmits, I always receive the TXD(48) DM1621...   Please advise,      
  16. Dear reader, I am writing a C# program using the library  ‘EasyModbus’ that needs to communicate with Siemens WinCC via the connection type ‘Modicon modbus’ I have written a version using the ‘float’ data type in WinCC and that works perfectly. Here my code fragment: Method to convert ‘double’ to bytes in C#: public static byte[] DoubleToModbusFloat(double value) {     byte[] bytes = new byte[4];     float floatValue = (float)value;     int intValue = BitConverter.ToInt32(BitConverter.GetBytes(floatValue), 0);     bytes[0] = (byte)(intValue >> 24);     bytes[1] = (byte)(intValue >> 16);     bytes[2] = (byte)(intValue >> 8);     bytes[3] = (byte)intValue;     return bytes; } Call of the method and loading of the modbus registers in EasyModbus: Bytes = PublicCode.DoubleToModbusFloat(TmpDbl); int n = (int)ModbusStartAddress + ((i - 1) * 2); mb.ModServer.holdingRegisters[n + 1] = (short)((Bytes[0] << 8) + Bytes[1]); mb.ModServer.holdingRegisters[n + 2] = (short)((Bytes[2] << 8) + Bytes[3]); So far so good – this works fine. But I also want to be able to use the ‘Double’ data type in WinCC because I sometimes need more precision than the 7 figures of the ‘float’. I thought it would simply be a case of doubling up the code so I wrote: Method to convert ‘double’ to bytes in C#: public static byte[] DoubleToModbusDouble(double value) {     byte[] bytes = new byte[8];     long intValue = BitConverter.ToInt64(BitConverter.GetBytes(value), 0);     bytes[0] = (byte)((intValue >> 56) & 0xff);     bytes[1] = (byte)((intValue >> 48) & 0xff);     bytes[2] = (byte)((intValue >> 40) & 0xff);     bytes[3] = (byte)((intValue >> 32) & 0xff);     bytes[4] = (byte)((intValue >> 24) & 0xff);     bytes[5] = (byte)((intValue >> 16) & 0xff);     bytes[6] = (byte)((intValue >> 8) & 0xff);     bytes[7] = (byte)(intValue & 0xff);     return bytes; } Call of method and loading of the modbus registers in EasyModbus: Bytes = PublicCode.DoubleToModbusDouble(TmpDbl); int n = (int)ModbusStartAddress + ((i - 1) * 4); mb.ModServer.holdingRegisters[n + 1] = (short)((Bytes[0] << 8) + Bytes[1]); mb.ModServer.holdingRegisters[n + 2] = (short)((Bytes[2] << 8) + Bytes[3]); mb.ModServer.holdingRegisters[n + 3] = (short)((Bytes[4] << 8) + Bytes[5]); mb.ModServer.holdingRegisters[n + 4] = (short)((Bytes[6] << 8) + Bytes[7]); However, this code does not work correctly. I have tried all combinations of byte and word reversal, and whatever I do WinCC either displays nonsensical values or ‘####’ showing that it cannot display the value. I have tried reading as much documentation as I can but it still looks to me as if I am doing the right thing. Also, I have downloaded a number of ‘modbus master’ code examples, and they seem to be able to read the ‘Double’ from my program without any issues. In WinCC I also see that there are two types of double – ‘Double’ and ‘+/- Double’ – I am also unsure as to why this is – there is no ‘+/- Float’ data type, which seems inconsistent to me. I am obviously missing something, but cannot seem to discover what exactly. I hope that someone can point me in the right direction as to what I am doing wrong. Please see attached word file for a picture of the configuration of the connection in WinCC.   Thanks in advance for any help !, Dave Long Double trouble.docx
  17. Does anyone know how to delete the row labeled as, "63 - station number" and "Driver - Host Name". Our IPs range from .50 - .90, I would like to associate the station with an IP that correlates to one another.     For example, Station 50 = xx.xxx.x.50, Station 51 = xx.xxx.x.51, etc However, when I go to add a station 63. I get the error dialog that tells me 63 can not be added because it already exist. I have had this problem in the past, but never got around to wanting to figure out how to solve it.    ** Jumped the gun ** (modified)  You can rename 63 to whatever number you choose it to be....

  19. Hi All, I am Data Transferring Arrays of WORD's from a HMI to NX PLC. This Transfer may be a variety of data types, Likely just UINT and STRING[20]. It will be Imported to NX as an Array of Word What im trying to do is Populate my Structure from this Array of Word. I can do this by mapping them individually just fine. But i was hoping i could add them automatically. Much like when you assign EthernetIP tags and can link them to a structure and User Offset the Bytes. But i cant seem to Link the Array of Word to the Structure e.g. SENSORS_STORED:=DATA_2_IN; Says its impossible Anyone have any ideas how i could Populate this structure from a WORD Array without manually mapping and Converting Each? SENSORS_STORED.Fixture_ID:=WORD_TO_UINT(DATA_2_IN[0]); For Example is a workable way but is long winded and was hoping there is a easier way Thanks in Advance Dann  
  20. Data register over flow

    Hi, data registers are getting full, because of extremely high speed pulsing is there any way , if the data value in register goes above the capacity of 32 bit register, it automatically attaches itself to next set of data registers so lets say if data was written in D10,D11 Upon reaching the limit, it goes to D10, D11, D12, D13 please share if there is an alternate way to do this

  23. As the industry of plc and scada softwares continue to integrate more and more programming languages into their IDE, what is the most common language that should be learned by controls engineers (excluding Ladder Logic)?  I mainly use Python and VB for scripting but I am curious what languages other SCADA and PLC programming environments use. Should I be sticking to a specific language and learning it well or just know a little bit of them all? Let me know your thoughts!!
