    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.

    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.

    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.

    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.

    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.

    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.

    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.

    If you choose to compile your runtime in version 3.10 or earlier all the user accounts setting in the Runtime Security remain unchanged even you do some modification to your project file, so don't worry just go ahead with your download. However if you choose to compile your runtime in version 4 or later all the previous user accounts setting in the Runtime Security are ingonred and you need to create new user accounts under the "ME Runtime 4.00 and later tab"
