Thanks for all of the responses and information provided. It looks like I have just 2 options... RS-232 or the 1756-EWEB module. It would be nice if I could print from the 1756 controller directly to the Zebra printer using the existing ethernet network, but it appears that some additional hardware is going to be required.

I would like to generate bar code labels in a system that contains a control logix controller and a Zebra printer. They are connected via an ethernet card in the PLC rack and a router. I have experience generating labels for this printer using a PC and the ZPL programming language, but I am not sure how to do it using a PLC. Is it even possible, and what commands would I use to do it? If it is not possible via ethernet, RS-232 is an option. Any suggestions would be welcome. Thanks!

I can do this, but I was hoping that the panelview could restrict access depending on the operator while still using the PLC to control the screens.

Does this mean that I have to use an operator tag and also restrict screen access via the PLC? I changed the security settings under the Panelbuilder 32 application settings as you suggested, but I can still go to the "secured" screens while logged in as an operator for whom I haven't given access. The settings do not appear to apply when using a screen tag and selecting the screens via the PLC.

Yikes! I thought I had issues to resolve.

I am using a Micrologix 1200 controller and PanelView 300 Micro interface. I have several configuration screens defined, and I need to password protect them. However, I also need to select the screen using the controller and a control tag that I have defined. The "Secured" option in Panelbuilder 32 only works if I disable the control tag and define a "go to screen" button. Is there a way to password protect certain screens while still being able to control the screen selection via the PLC? Any help would be greatly appreciated!

I figured out the powerup issue. I changed the value of bit S1/9 (startup protection) to "0". The factory default was "1" or on.

I changed the PV configuration by unchecking the "write to controller on startup" option. This seemed to work. Thanks! However, I have discovered another issue that has me scratching my head. If I have a power outage, the processor faults when the power is restored. In the processor status file, I see the following error: "Startup protection after power loss. Error condition exists at power up when bit S1/9 is set and power down occured while running" Is this a setting that I can change? I want the processor to restart and run when the power is restored.

I am putting together a system that includes a ML1200, an analog input module, and a PV 300 Micro operator interface. I have defined several PV screens that allow the user to change scaling constants and test limits using numerical entry fields. The tags point to addresses in the floating point file of the ML1200. This works good, but I have noticed that if I download to the PanelView or if the communication to the PLC is interupted, it reinitializes all of the values in the PLC to the default values of the numeric entry fields (all zeros). When this occurs, I have to download the program to the PLC to restore the values. Is there a way I can prevent this from happening? If I protect the F8 file, it will prevent the user from changing the values through the panelview screens. I am thinking of making a copy of the F8 file and copying the values back to the F8 file if it contains zeros, but I am hoping there is a better and easier way to protect the values. Any help would be greatly appreciated!
