I'm new to using RSLogix 5000 and I'm not sure how to handle memory protection.  I build recipes from an HMI and store the data in tag arrays on the PLC. I'm used to doing this with the micrologix plc line and in Rslogic 500 I could simply mark the data file to not overwrite when downloading. Is it possible to do something similar with Rslogix 5000? if not, is there a better way to handle recipes? I just don't want to overwrite recipe data by downloading a program update.  

Have  you contacted Red Lion support about this?

Sorry it took me a couple days to get back to this. Yes I'm going to use one of the ml1400s just to handle a bunch of analog io. I'm just going to msg that data every few seconds to the other unit. thanks

One other question please. This system will have 2 micrologix controllers. One will just be used as an IO device. The other will do all the processing and needs to be able to read from the first controller. Does the Panelview support passing tags from one controller to the other? thanks

Gareth can you post what your are trying to do. I may have some code that I can provide.  

Thanks to both of you. I think the PV+7 is going to be the winner.  I'm the loser :)...  

I have a customer that insists on me using a panelview for his project and I have basically no experience with them. I have been using another brand exclusively for many years so I'm well versed in how to use an HMI, just not Allen Bradley. I'm hoping to get some advice about which unit to use. The system is a simple waste water facility and the controller will likely be a micrologix 1400. The customer wants something in the 15" range. Looking on the AB website I see Plus 6 & Plus 7 both seem to give me that size. Are major differences that I should know about? thanks     

So are you uploading or downloading? When using rslogix500 if you want to send the program to the plc you need to use 'download'.

Did you connect the dc common to the comm2 terminal? Also do you any load on your output or are you just looking at it not connected?  

I would try to isolate the problem a little more. If it's a noisy input, then remove your signal and give it a known source. You can put a resistor from a power supply in series with the input and then watch the value in rslogix. If it's a noisy output, then poke a value into the output address and measure the output with nothing else connected( you'll need a resistor of course if it's a current output). My guess is that if you're talking about an input, it's the device sending the signal to the plc and not the module.  I've used a lot of these older products and I still have customers that have systems from  the early 90's that are still going strong. Run some tests and let us know what's happening.  

You can use the NPN output of a sensor but if the sensor doesn't have a built-in pull-up resistor, you'll have to add one externally. Can you tell us what sensor and input module you're using?  

Just an FYI.  I re-installed the update this morning and it's still broken. All my other updates were 'up to date' so any patches to this problem should have been installed.... I should be programming instead of dealing with this mess.....  

I am using AdvancedHMI to log data to a sql database. If you know sql, it's easy to generate reports. It's very simple to use and if you are familiar with .Net VB or C#, you can have it up and running in no time. Also it's free and an excellent product with great user support. Just my 2 cents...

You would have to create the security settings within Crimson 'Security'. There is no facility to authenticate users from another device. You can however,  create a security database from within crimson and write/read with an SD card.  This can be useful if you allow users to change their passwords.  

Thanks Ken. I rolled back the update and set a group policy so it won't automatically install. I'm hoping a permanent fix is coming soon.
