  1. Hello I have a scenario that's been bugging me for some time now. The scenario consists of a Micrologix 1400 that I need to control it's output from modbus/tcp. In detail what I really need is to be able to manipulate the O0:0 through modbus/tcp. The PLC would be the master and I would be the slave that triggers the connection to the master. I'm using a Modbus-Client on my PC and that should be the slave. Any idea as to how I can manage that? Currently I can send data to the master but everything is "stored" on B10 and I have no idea how I could write directly on O0. Thanks a bunch guys. PS: I'm borderline noob. 

  2. Password Protected LS Master K

    AkumaShi posted a topic in Other PLCs

    I have a customer that has a LS Master K PLC, and he needs me to make some changes to the program. I am not the original program writer so I do not have the original program nor the password. And the company that originally made this program does not exist anymore. Does anyone have any suggestions on a software or a device that can help me either find the password or just bypass it. I need help ASAP Please!!!!! I saw there is a password breaker while i was googling, but the software cost $50, and it looked a little sketchy so I am kind of hesitant to trust 1 purchasing the software and 2 downloading it only my work laptop. Please help!!

    karim_ posted a topic in Other PLCs

    Hi, I’m trying to control 10 Safety switchgear using AS interface, and since I’m using Beckhoff as a PLC I want to use "KL6211 | AS-Interface master terminal" as a Gateway but since this is the first time I’m using Beckhoff I’m a bit lost, So my questions are: -          Is it a good idea to use a Beckhoff ASI terminal? -          How to configure it? -          Is there a possibility to configure it using embedded PC ( I’m using CX2030)? Excuse my English.

  10. Master/Slave Communication

    MZohaib92 posted a topic in Other PLCs

    Hello guys, I am using Fatek PLC's to communicate with each other as a Master & Slave through zigbee which is connected through RS485. And I succeed. But the issue is that I have to communicate each other at a distance of about 2km where zigbee out of range to each other. I am bit confused here; 1) whether I use RF booster? Does it work? 2) Should I introduce extra PLC as a repeater between master slave? But this(extra added) PLC repeater also become as a master(Master Repeater).or any idea? Most important I can using Fatek Protocol or Modbus RTU or Modbus ASCII prootcol.

  16. Hi,  i want to read real time and date in simulation mode. How can i do this in Unity pro? Thanks for helping
  17. Hey Guys,i'm working on implementing the master side of a custom serial master-slave protocol between a B&R PLC and an electronic card.As part of the data i'm sending and receiving is used to close various loops(e.g. cascaded temperature control where the temperature sensors and actuators are connected to the electronic card) , but other data is not as usefull (e.g. various data used for display or at specific times), i believe i will also need to implement some sort of priority mechanism.my first question is - based on your experience - how would the general master side SW architecture look like? (for example - the send side of mine is comprised of 3 tasks all running under the same cycle - lower level task in charge of opening the port, sending the data etc, a mid level task in charge of creating the packet based on command from upper level, giving commands to lower level and using status from it to continue and finally - an upper level task in charge of deciding which messages to send).my second question is - how would you implement the priority mechanism?thanks

  18. NB Display MASTER SLAVE

    manowar posted a topic in Other Omron Software

    Hello.   I have a question regarding NB series display. The comunication is made through RS232 / RS485 comunication. I would like to use NB display as MODBUS MASTER and SLAVE aplication. - Display would work as MADBUS-MOSTER to talk to plc controllers. (Working through COM2 - RS485) - Secondly, Display would work as MODBUS-SLAVE to talk with (SCADA). (Working – Registers LW, LB))   What I have trouble with, is: - I would like to change variable in the PLC - for example : Regime_PUMP (address: 0x0001). - Regime_PUMP variable should be settable from all three devices PLC <-> DISPLAY <-> SCADA So: - If I change Regime_PUMP through PLC it should refresh also on DISPLAY and SCADA. - If I change Regime_PUMP through DISPLAY it should refresh also on PLC and SCADA. - If I change Regime_PUMP through SCADA it should refresh also on DISPLAY and PLC.   Does anybody have an example for NB series of display to do this?   Best regards.

  21. Good morning, I'm having an odd issue with CX Programmer and have hit a wall. I'm trying to upload a previous version of a program to an existing PLC (CS1G-H CPU42) and I keep getting the following error when I compile while online: "The read protection properties which are not supported by the connecting target PLC are set. Check the unit version of the PLC." This prevents the program from being uploaded. I have a first revision CS1, manufacture in 2005 from what I can tell. This exact program has been uploaded previously, but a modified version replaced it recently and I need to go back to the older version. Things I have tried so far. without success: - Removed UM Protection - Made sure Task protection is off for all tasks - Check DIP Switch #1, which is write protection, and made sure it is off - Used "Remove Password" and "Release access" functions from the PLC/Protection menu - Used the auto-verification to confirm the configured PLC is correct - Reuploaded a full backup of H & D memory, from the older program I am able to compile the program when offline, but it chokes when online. I am connecting to the PLC via a serial cable. I haven't found any help from the CX Programmer help, or the CS1 programming and operation manual. This error message is nowhere to be found. Anyone has a clue ? I'm at a loss right now. Thank you !

  22. PLC Integration by SCADA

    Jairus posted a topic in Siemens

    Hello Experts, Good day to you all. I just can’t figure how I will integrate five S7-300 PLC. CPU 315-2dp. (1.Blow moulding-> 2. filler-> 3. labeller-> 4. packer-> 5. Palletizer) I just want to get the speed of its machine, the output rate and the alarm, this is purely monitoring, archiving, no need to control anything here. I planning about SCADA system. I’m thinking if I could do the same way in my previous project, which I’ve done in profibus master/slave for two s7-300. But this time the five PLC’s already set the profibus as master to the danfoss drive, sew drives, ET200s and many more profibus slave. I plan to buy 1 PLC as master and I will set all as slave, but how since all the five existing PLC, its profibus already configured as master. Thank you very much. All your inputs is really appreciated.
  23. Hello All, I want to read data from a Control Logix PLC, into a PLC5/60, using Ethernet and a MSG instruction in the PLC5. When verifying the MSG instruction in the PLC5, I get an error message. "Target Address in invalid". Once I figure out how to do this I need to replicate it in another PLC5. Scope is to read the status of 4 paint pumps controlled by the CLX. If any of the 4 stop, the PLC5 needs to know, because it is controlling the paint application equipment. Source data resides in a Control Logix 1756-L63. The tag is INT type, 4 elements long, and the name is PUMP_STS_B2. The IP address of the CLX is 4.2.6.230. There are 2 ENBT cards, one in slot 1, and the other in slot 3. 4.2.6.230 is slot 3. PLC2,5 / SLC Mapping has been created in the CLX. File=421 Name PUMP_STS_B1 and File=422 Name Pump_STS_B2. The file mappings represent a binary file created in each of the PLC5's B421:0~4 in Booth 1, and B422:0~4 in Booth 2. The PLC5/60 is Enhanced series E model using the Ethernet side card. The IP address of the PLC5 is 3.26.5.61. I also created MG file types in each of the PLC5/60. MG420:0~19 in each processor. This was necessary to use the MSG instruction in the PLC5. I have searched the forums for examples of how to do this with no solid results. I am trying to follow the best practices of reading the data into my PLC so anyone who follows can tell where it is coming from. While the IP addresses are not closely related they should be able to communicate. I say this because all of our PC's are on the 4.2.6.XXX network on a 255.255.252.0 sub net and we have no issue communicating with the 3.26.5.61 IP address. Any help and advice would be greatly appreciated. Regards, Mike Carter
