  1. Is it possible to add another AB Rockwell PLC to the network tree as a Generic Ethernet Module and use it as IO? Any idea where I would find information regarding assembly instance and size of I/O/C for AB Rockwell products? If possible, what are the pros and cons when compared to produce/consume and MSG instructions? Don't need to use it real world, just curious. Many thanks in advance.
  2. I have multiple PVP 1500's on the same network. From the one in my control room i need to be able to see what user is logged into what HMI. How would I address the system tag of another HMI on the same network would I use the IP address? thank you for any help in advance
  3. NX-105 Received Data

    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! 
  4. Delta PLC Analog Noise Reduction

    Hello All, I am Using Delta SE Series PLC and 06AD Module for Pressure Transmitter. But Analog input get fluctuate continuously. Is anybody have program for analog scaling.
  5. Hi guys! Can anybody help me? I have an existing controlnet network. How can I connected a new module? Like an 1794 IB16. What should I need to do after I connected the new module? One more question: What's the difference if I do not connected the new module right after the last module, but I connected between already existing module. Then what should I need to configure. If anybody want to help, please write like step by step. I'm a beginner, but I want to imporve myself. Thank you for your help. I almost forget, I need to work with Allen-Bradley PLC, and I have RSLogix 5000 software.
  6. 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!

  10. All, I am using Keyence CV-X422A vision controller for my application. It is interfaced with Siemens S7-1500 PLC on PROFINET. I am able to communicate with Vision controller through PLC logic command and status IOs. There is some communication issue in updating the o/p values from Camera Controller. I have tried with & w/o Handshake Mode with these settings. The camera display shows the reject but camera never turns ON the NG Status o/p. I tried different things told by Keyence Tech support but none of them worked.  He told me to have you enable the “Result ACK Flag” in the bit allocation area and send  a signal to it. Then trigger it again with a no good part and see if that fixes the issue. I tried setting the “Result ACK Flag” to 1 after I get the “Command Complete Flag” for the trigger signal that I sent. Sometimes this works but still it is not reliable. Do I need to send only a pulse to “Result ACK Flag”? Anyone here has ever faced similar issue?  Thanks for your help. AP
  11. My client is a pharmaceutical company and they want to interface their Blood Gas Analyzer (which is a RAPIDPoint 500) to a Controllogix PLC via EtherNet. I have attached a Spec that I found, which gives the initial information you would need to do this. It says that the BGA can transmit data in ASCII. However, it doesn't list what bits I need to send to the device in order for it to send the PLC the data. I've tried contacting Siemen's (who makes the BGA) and they were useless. I also tried searching the RA knowledgebase.  Does anyone have any insight on how to communicate with a device in this way? Thank you Tyler RP500_LIS_5_20_13_-_Rev_C_.pdf
  12. 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?
  13. I first saw AS-i at a factory this week and am trying to figure out what Allen Bradley modules can interface it. I am not finding anything, does AS-I go under some different name?
  14. RS485 Async

    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? 
  15. GX Works2 & MX OPC Server 6.10 issue

    Hello! What i am about to do is connecting an external SCADA system to a Mitsubishi PLC via OPC server. I have already made some FBs and included their instances in a program in GX Works2, then started a GX Simulator2 and connected it to an OPC Server. From the OPC configurator I have defined some tags with their corresponding device addresses (e.g. D12345). I am using structured variables which device addresses i am entering in the OPC configurator. Tried to make some full rebuild compiling and at first was happy that the devices remain unchanged. The main problem is that after some time this devices change which completely ruined my experiment. Maybe there is some point that I am missing or there is just no way to use a fully functional SCADA connected that way to the Mitsubishi PLC (by OPC)? The question is is there a way to tell a particularly used instance of a function block to have exactly the same device addresses ever. 
  16. Hello all  i'm looking for some software to record a 100 plus channels maybe with an ascii string from a PLC? i want to be able to assign each channel with a unit and a range, flagging feature would be nice.  - selecting the channels i want to view  - auto start recording - save file and start new automatically  -view and create reports  preferably no additional hardware because of the amount of channels. this is to record an operators every move so in events of damage or plant failure we can quickly identify the problem (point the finger)  many thanks dan

  18. Hello,             I need to communicate Power meters ( GE Multilin EPM 5500P) to  GE Multilin EnerVista Software. The present communication system uses Ethernet for communication from LAN Switch to Computer. There are a few existing Power Meters which need to be connected to the  Network. The Meters having output ports as RS485. I need to use a convertor for that right. So when I contacted GE they told me to use GE Multilinet Serial to Ethernet Convertor. But due to the price and unavailability of the material I am thinking to use a universal convertor. Is that compatible for Multilin Devices?? and In Case of using a universal Convertor does we need any other drivers for that. Please Help Me.. Thanks In Advance  mnetman-a3.pdf multinet (1).pdf PM-GE.pdf
  19. NB7W System Error

    I’m programming a OMRON NB7W-TW01B with NBDesigner and after I download to the HMI updates I made to the program, when the HMI initializes it shows “[0] System Error” for a while and then it disappears, not showing again until the next reboot.   The manual only says it is an HMI internal error and nothing more, leaving me clueless about what I can do to fix this issue… I already have updated the kernel and rootfs of the HMI, nothing changed.   What do you guys think the issue is, what should I check to try to fix this problem?   Thank you very much for the help.
  20. Looking for some servo application help. Software: I have GX works 2, GT Designer, and GX Developer.  Hardware: PLC L06CPU-P, GOT2000 HMI, MR-J4-350B servo amps, HG-JR35JK motors, LD77MS2 Pulser I have (2) AC servos that will simply move an aluminum frame backwards and forwards using a FESTO belt mover and I have a servo gear reducer 20:1. I have a "simple motion module"and all of this hardware and software, plenty of time, and would really like to finish this project off. But this is my first servo and my first hmi project. I have some experience with Omron, Mitsubishi, and Allen-Bradley plc's, and consider myself novice at best. Any sample programs or help getting me started would be greatly appreciated!  
  21. Hello, I am currently working on programming my first sortation system.  Attached is a blue print of the in feed conveyors and their loadout lines.  As boxes merge together they will be scanned by the barcode scanner.  From there we will be told which lane each box must go down, from the WCS.   My question is, without encoders, what would be the best way to control this system? Counting the packages as they pass through the photoeye? Or setting timers?   Thanks, James Sorting Conveyor Layout.pdf
  22. Hi, I have encountered an unexpected "PRI" LED indication of 1756-RM Series B module. When the affected redundancy module is set to primary, the status of the "PRI" LED indicator is blinking red. On the other hand, it is set to a solid red when the RM is set as secondary. I have read the manual and there are only two expected behavior for the "PRI" LED indicator, green if it is set as the primary and off if it is secondary. Does someone encountered this scenario already?   P.S. The RM does not have any minor/major faults when accessed. The status indicator indicates "PRIM" when the affected module is set as primary and "SYNC" when set as secondary. Manual switchover between controllers are done and was successful. Thanks in advance! Regards, RIValencia
  23. Hello everyone, I have difficulty to setting up the GSM configuration or the serial RTU configuration so that I allow you with another RTU. I use Schneider CPU Modicon M340 in conjunction with RTU communication NOR0200H and a Modem Schneider SR02 MOD02. This is the first time I'm working on this kind of project, want to help me, I'm stuck and I need a solution, thank you for your time.  
  24. Hi to everyone,    I have done an intense search on the web and this form, also went on to the download section here to try out a simple RS232 program, so far I can't get it work. Long story short, I am working on a PLC CP1E( w/ built in RS232) to communicate with the PC hyper-terminal . PC will send a string of messages to the PLC, then the PLC will convert the message to a pulse parameter, eg. computer will send ( 90, 40) to PLC, then the PLC will take the string 90 to pulses parameter( PLS2) and 40 will be the duration period. I am willing to learn and try out your sample program, let me know! THank you in advance.  
  25. hello everyone, I'm trying to connect PC with Micro830 with RS232 cable for transfer serial data. However, the PLC can not receive the character from PC. I used ARD function block to read the characters from PC.  there is no error and the output of ARD function block is 0 when I debug ladder programme. the serial communication state LED illuminated once I send a character from PC to PLC. the channel of input is 2 which is the embedded serial port. I use an adapter from USB to RS232. Email: jeremietang531@gmail.com
