MSG Message from a Micro800 to a Powerflex 525 Drive 

Thanks, those would be good topics

Yes that is the nicer option in my opinion. Putting out a video on it next week.

@@TimWilborne It has a lot of good stuff to use in the block. Excellent videos, keep them up!

That would be a good one John. I'll put it on the list.

I have a PLC training class this week so no time to look but the same code you used in the Micrologix 1100 should work in the Micro800. You would use the CIP Generic Message.

It should be possible but it is going to take some modifications to the UDFB.

Here you go Tim. www.rockwellautomation.com/search/ra-en-US;keyword=95943;startIndex=0;activeTab=Sample_Code;spellingCorrect=true;facets=;languages=en;locales=en_GLOBAL,en-US;sort=bma;isPLS=false;sessionID=b144a2f6-46ca-fa1b-5507-f1ef18de2efc;deepLinking=false

Which adapter are you using to connect the Powerflex 523 over Ethernet? Also what are you trying to control it with?

@@TimWilborne I am using a Micro850. All of my componets are connected to a main switch. I traditionaly download the PLC with usb. I have successfully uplaoded VFD parameters through ethernet (port1 on the VFD) with CCW implying I have a solid connection to the VFD. Thank you so much for your quick reply!

@@dylanimbus3659 The messaging parameters are different for the Powerflex 523 but the User Defined Function Block method should work fine with it. See link below. twcontrols.com/lessons/control-an-ab-powerflex-525-drive-with-a-micro800-micro820-plc-with-a-user-defined-function-block

dyan you can by a ethernet card for the 523, or you can use the analog on the drive to feed back info.

Just create BOOL tags

It is assigned some special purpose such as an interrupt. Click on the controller at the top of the left pane then go to the Interrupts section and see if the program is shown there.

@@TimWilborne ahh! I have indeed assigned an interrupt. Do you know if there is documentation for this or did you just learn through experience?

The one learning curve that I have not overcome in Connected Components Workbench is its use of symbols to indicate things without any text. I can't decide if it is a bad design or my struggle to embrace emojis to tell me what is going on with a machine.

@@TimWilborne I'm glad it's not just me then! I also get warnings telling me I should UID/UIE protect code to lock threads. When I do this it continues to tell me I should do it, even though I've already done it! I know they are just warnings but I'd like not to have 20 of them every build! I'm sure the software will get there eventually, it's no TIA portal or Unity that's for sure! But the price keeps my employer happy!

@@lewsut Yes and Rockwell Automation has continued to tweak the software to make it more user friendly. Probably what is missing from these icons is some type of mouseover function telling what they mean. Also, the mystery icons are an improvement over RsLogix 500 where it didn't tell you that a routine was used for a special interrupt.

Yes, otherwise a message instruction will only execute on the initial scan.

@@TimWilborne Thank Lord Tim, don't need to trigger, micro800 to acs580 ODVA. with your advice, i put the default ip adress on micro800, i put the same range of ip adress on the 3 ac drive. now it work find ! thank you. how much cip generic message we can drive in 1 scan on micro800 ? (sorry for my english)

@@silluc21 There is a limit of the number of messages you can send per scan. I don't recall what it is off of the top of my head but you should stagger the messages. Google cascading timers, it is how I usually do it.

Yes, for the most part I like the improvements of it. I might do a quick video on the changes of it in my next batch of videos.

@@TimWilborne that would be great

It is on the list Andres.

You need to change your PC's IP address, you are getting a duplicate IP address when you plug into the Ethernet switch since it is the same as the Powerflex 525.

Okay thank you!

I should do that, I'll put it on the list.

@@TimWilborne much appreciated mate Thanks again...your videos are much informative n detailed

Hi William. I have one coming on stepper and servo control with a Micro850. I'm struggling with the feedback for a Powerflex 525 drive. I'd like to be able to do it with the 3 phase fan that is on the trainer. Any thoughts?

@@TimWilborne Hi Tim, Thanks for the reply. My experience with micro 800 series and CCW is only from watching your channel. 🤔 Haven't even got our hardware yet.. Thank you for all the great videos on CCW btw. I work on omron most of the time Siemens Schneider and the rest never AB done some slc500 PLC's but not motion. I have a project coming up which is using a micro 850 with 6 3ph motors using 6 encoders for position.(servos must have been too expensive) It's for lifting machinery off an agv in a manufacturing cell with x,y and z movemment, so 3 pairs of motors. The vfds have not been specified but the plc has to be an AB , we have went with micro 850 again because of cost. So I was thinking powerflex 525 just because of the ethernet IP comms capability with the micro850 rather than a different brand of vfd. So the plan is 525 with encoder add on module, the Micro 850 to a send the position setpoint over EIP to step 0 on the vfd (L200...L214 step no.s). I believe the value is sent to 2 consecutive addresses so L200 and L201 FOR STEP 0. Hard wired switches in the plc for home/zero pos which I read in the manual can be done over Comms aswell. Hard wiring the steps would be no good as it's limited to 8 positions. I need at least 25. I would like to have all Comms over Ethernet apart from safety. I downloaded a user FB from the Rockwell site which has the functionality for position control although it just sets the bits for vfd step positions rather than dynamic values from the plc, although this can still be utilized but I need to send a setpoint before triggering the step 0 bit. I think it's do able, the position setpoint may need to be done with the messaging instruction you used on a previous vid. For your test rig you should have all the equipment although not sure how you would have the encoder reading the fan rotation. I think you would need a small motor as it would be hard to use your pulse simulator.

@@williamhaggan4812 Look at the specs of the different Micro850s, many of them have built in high speed counters. You would still need plug-in high speed counters but not as many.

I'm going to do some messaging video soon and that will cover the Powerflex, Compactlogix, and MIcro800.

@TimWilborne please can you include RS500? It is still very widely used. And for beginner-improver like me, this is a very good choice because of its price and versatility. Thank you :)

That is what I mean. I'll be doing Micrologix videos on how to communicate with each of those. But you should be looking looking for a Micro800 with Connected Components Workbench. Its software is free and there are economical PLCs as well but it has many more capabilities.

@@TimWilborne Thank you!

You are welcome
