  1. Peer to Peer MSG CLogix to SLC (Help)

    Yes MSG Write and MSG Read will work fine between CLX and PLC5. Just use the PLC5 Typed Write or Read in CLX coding.
  2. Compact Logic

    Change your CompactLogix controller to Emulate 5000 Controller. Only Emulate 5000 Controller can be used for emulation. You need the RSLogix Emulate 5000 software.
  3. Compactlogix to RSview

    what version of rslinx are you using? the rslinx lite version cannot be used as opc server.
  4. Panel View Plus Login audit results to SLC 5/05

    Here is the solution if you want to track the current user in the SLC. Here I'm using FTView Studio ME: 1. I create a common memory tag name call set_login. 2. I create 2 macro, 1 for login macro and the other for global macro. 3. The idea behind this is to use the 1 macro to initiate the second macro only after the system/User tag has been updated by the current user name. 4. I use the first macro as login macro which will set the set_login tag to 1. 5. When the set_login tag change to 1 it will trigger the global macro which will write the system/User tag value (now with the current user name) into the SLC string and reset the set_login to 0 ready for the next login. Hope this will solve your problem.
  5. Panel View Plus Login audit results to SLC 5/05

    It is the login delay problem. As you login RSView will assign the previous system/User value which is "DEFAULT" in the the string in SLC. You can login the second time with the same user name and you should notice the string in SLC will be updated to the current user name. So your SLC is actually recording the user name of the previous user not the current user.
  6. sqo success

    How do you trigger the SQO, by timer or hardwire in put? How you trigger the output, by using indirect addressing? Do you mind post your PLC code so that we could take a look.
  7. IEC codes in specification sheets of AB hardware

    You can download the safety certification for the AB hardware here. You will find the EMC test is already included in the certification. You can print out all the relevant certification which proved that this particular A-B hardware already meet all the EMC requirement and show it to your client. I know that sometime some client might be quite demanding on this issue, but I never try to shown them how this particular A-B hardware comply to the IEC standard. This part already done by Rockwell and they already have the cert to prove it. I think what the client really want is just some paper work or document to present to their management that prove A-B hardware is reliable.
  8. ControlLogix and Keyence

    I'd experience with other serial devices, but not a laser controller. In my previous project I need to use the ASCII Read (ARD) and ASCII Write (AWT) that send command and receives data from the serial device via the PLC's serial port. Unfortunately both these instruction only work on a real serial port not the the Ethernet port. Maybe you can check out this product which add extra serial port to your PLC system.

    I'm not sure what is the problem here, maybe you can elaborate some more. Most of the time I'll set the PLC Ethernet port to Auto Negotiate there is no harm to try other Port Setting too.
  10. Panelview plus not talking to Emulator PLC

    Here is the proper way if you want to connect your PanelView Plus to RSLogix Emulate 5000 via Ethernet: 1. You must not delete the RSLinx Enterprise slot from the Emulator you must left the it running as shown in the following picture. 2. Open out your FTView Studio. Open any project and under the Communication Setup, right click on the Ethernet and select properties. Under the Ethernet properties tick the Listen on Ethernet/IP encapsulation ports and your RSLinx Enterprise's Ethernet communication port will be available through your PC's physical Ethernet port. 3. Open your targeted PanelView Plus project's in FTView Studio. Under the Communication Setup, right click on the Ethernet and add the device driver for RSLinx Enterprise (Check your revision, most properly will be Major Revision 2). You need to key in the IP address for the PC where you run the RSLogix Emulate 5000 4. Under the RSLins Enterprise driver add the RSLogix Emulate 5000 virtual PLC as your project device shortcut. Appreciate you could feedback on your process after trying this method.
  11. ControlLogix and Keyence

    First you need to determine what communication methods are available on the laser controller. Next you need to see determine whether these communication methods are compatible with ControlLogix. For your information ControlLogix have serial, Ethernet, ControlNet, DeviceNet, etc.
  12. NODE

    Here is the manual for your reference: http://literature.rockwellautomation.com/i...um006_-en-p.pdf According to the manual you need to give each PLC a node name this node name have nothing to do with the name you assigned to the PLC it is only the name for HMI tag reference. Each name name will corespondent to each PLC with different node number (indicated as Station in HMI). The node for the PLC is assigned during programming in RSLogix 500, so it cannot be change in HMI So if you give a node name LC1 to PLC 1 with node number 1, then in your HMI tag, the reference will be Node name: LC1, Address: B3:0/0. See the node number will no appear in a HMI tag reference because the information is already encapsulated in the node name.
  13. Panelview Plus 1500

    Try re-flash the firmware.
  14. NODE

    May I know what type of HMI are you using? As I know Rockwell HMI will not use the PLC name to get the tags from the PLC. In the HMI you need to create a device shortcut that point to the target PLC and you assign a name for the shortcut which later will be use as reference in the HMI tags.
  15. Panelview plus not talking to Emulator PLC

    You can try using the Emulator's Channel 0 serial port by connecting a serial cable between your PC and the PanelView Puls terminal. Btw you can remove the Slot 1 RSLinx by terminate the RSLinx Enterprise service. Bring out the Windows Task Manager and end the process called "RSLinxEG.exe". You will see that the Slot 1 is now empty. RSLinx Enterprise is the native communication driver for FT View product and it will start automatically whenever you start the FT View Studio.
