Hi All, We are currently upgrading one of our machines which is controlled with a PLC5/40E I think it is Series E Rev A. The reason I'm not 100% is that it also says DH+/RIO Comm Plug #1 Series/Rev: A/A. (I have included a screen shot of this) Anyway, we are looking at replacing some of the older drives with servo drives in a Master/Slave configuration. For this type of setup we communicate to the drives with a DeviceNet Scanner. Our plan is to use a Compact Logix Processor to control the drives and communicate with the PLC5 over Ethernet via messaging. I have not had any experience with this type of setup and am wondering if anyone knows of any problems we might face. My first concern is the PLC5 FW I believe it will need to be upgraded to at least D.1. I was also wondering what sort of Lag we might experience with the messaging between PLC's setup? Any advice/comments are gratefully accepted -
Thanks for your reply BobLfoot, I can see that your script will work. I think my question wasn't too clear... With RSView It seems that all the scripts are event driven? Is there anything built into the application where I can place some script that will be called continuously? or do I need to patch something together like your example script to simulate this? -
Hi All, I am writing some script to check comms between Logix 5000 PLC and SCADA running rsview se. I know what I want for the script, my problem is how to call continuously while the client is running. is there an option for this? Any replies greatly appreciated Thanks -
Hi, Yes I have discussed the VBA method and found the following to work I inserted a Numeric Display into a screen that is always open or every screen that would have focus. Then r-click add VBA and the following code ("Alarms Current" being the name of my display) Private Sub NumericDisplay3_Change() If NumbericDisplay3.Value = 1 Then Application.ExecuteCommand "Display Alarms Current" End Sub My display screen opens when the value goes high the only bug is that I receive a runtime script error in studio "Type mismatch" But its working. -
Small problem causing a big headache. I am running RSView SE 4.0 and want one of my displays to "popup" when a bit turns true. I have set this up as an event but when the bit turns true nothing happens in the client and in Studio I get a warning which says "the command "Display" is ignored when issued from a development environment or HMI server" Does anyone know why this is happening and how to get around it? thanks
