So if you were using Snap7 and the C wrapper, you can easily replace both with Sharp7 library. One of the biggest advantages of having the full library in C is during debugging. You can place a breakpoint in Visual Studio and debug the messages sent and received from the TCP socket without having to leave Visual Studio and without having to use network sniffers or other external software.

I dont know your entire layout so you need to consider if there are other factors involved But it is a bit more complicated than that. First you need to know what Compactlogix you are using. Then look at each module in the PLC5 rack and see if they make a similar module for your compact logix.

If they dont then this may throw off your module sequence and logic behind the way you are planning this. Also is the Compactlogix you are planning to use capable of having 10 expansion cards attached to it?

Do you need even more than 10? Best to plan what hardware you are going to use to replace each piece of the old PLC5 rack and go from there. For each expansion module you pick you can download a data sheet that will show you how it needs to be addressed.

Until you know exactly what you are going to use, it is hard to say how you will address it. You dont want to rewrite and entire program and then figure out "hey this is not going to work". Since you will be going to an entirely different platform you will likely need to upgrade your HMIs also.

BCS Edited 27 Mar Using Allen-Bradley Controllers via Message Block Most Allen-Bradley PLCs and PC-based controllers (ControlLogix, CompactLogix, SLC5/05, PLC-5, SoftLogix, etc.) support serial RS and Ethernet communications, either built-in or through an add-on module.

The Block Transfer Write in my PLC-5 would have the following settings: BTW, Rack 3, Group 0 Slot 0. Note: if you have PanelBuilder E software it comes with some great example programs and ladder files.

Hello Thorsten! Thank you for your feedback, we are were glad that the post helped you out 🙂 About the power supply: The Tablet will feed the 5[V] (in practice it’s more about 4[V]) to the Arduino UNO or in your case the the JeeNode.

The PIDE (Enhanced PID) is an Allen Bradley Logix family (ControlLogix, CompactLogix, FlexLogix, SoftLogix) function block that improves on the standard PID found in all their controllers. First impressions of this function block are quite intimidating. If you try to dive into it head first you may just end up banging your head against a wall. Many will be quite happy to stick with.

Apr 01,  · Hello, I am a novice also and woking on a similar problem messaging between Compact and Micrologix. Anyway from what I understand about the PLC5 system we have is that the specialty modules, Analog, HSC, etc, are not directly addressed in the programing and you have to use read and write Block Transfers to .
