Before you trash the bad CPU or ship it to a Radwell or Rockwell for refurbish credit can I recommend you try a reset to factory conditions on the CPU.

With the old licensing the sector by sector clone would sometimes succeed as you proved. This was because the license was generating an invalid sector(s) that the licensing assembly code module could still isntruct the controller to read. But OS level copies skipped the faulty sector when copying breaking the license application. It was crude but elegant at the same time.

Just an off the cuff idea. What happens if you scale 3277-16383 to give you 0 to 50.
If that works stabily then divide that result by 100 and subtract 0.25 to get your final value.
I am suspicious that the SCL Block doesn't handle the negative value well.

Did not know that about the self learning router.

Had a rather strange problem with a 1756-DHRIO card on one of our systems today.
First the Hardware Layout -
PLC A - ControlLogix 13 Slot Chassis
Slot 0 - CPU
Slot 1 - 1756-ENET 10.5.1.10
Slots 2 through 11
Slot 12 - 1756-DHRIO 1 = Channel B Node 52
PLC B - ControlLogix 13 Slot Chassis converted to 7 Slot Chassis
Slot 0 - CPU
Slot 1 - 1756-ENET 10.5.1.20
Slot 2 - 1756-ENET 10.3.1.20
Slot 3 - 1756-CNB ControlNet
Slot 4 - 1756-DHRIO 1 = Channel B Node 32
PLC C - PLC 5 at Node 20 DH+
PLC D - PLC 5 at Node 1 DH+
Second the actions prior to the malfunction
PLC B was changed from a 13 slot to a 7 slot chassis with no change in other hardware.
Third the Issue with the system
Using RSlinx and Browsing 10.5.1.10 to Slot 12 and Channel B I see nodes 1, 20, 32 & 52.
Using RSlinx and Browsing 10.5.1.20 to Slot 4 and Channel B we see only node 32
Fourth - we moved the 1756-DHRIO to Slot 6 and it browsed the same.
Fifth when we changed the card back to Slot 4 and rebrowsed we saw node 1, 20, 32 & 52.
I can't explain why the card would start working after several minutes.

My employer just purchased a CNC system with a SINUMERIK 810D Controller.
Don't have any drawings or a lot of Siemens Experience.
Working with two S7-400's on another machine and in the thick of the learning curve right now.
How ancient is the 810D and when should we plan to have to upgrade it?

I am not an omron expert, but reading page 258 of the manual I propose the following:
You have two signals at play here - "Origin Proximity Input" and "Origin Input".
Using Detection Method 1 your system does the follwoing:
1) Moves at High Speed
2) Sees the "Origin Proximity Input"
3) Slows Down to Search Speed
4) Sees the "Origin Input"
5) Stops.
What I suspect is happening is your two sensors are close together and some times the system see the "Origin Input" at the same instance as the "Origin Proximity"
I would physically seperate the two sensor flags if practical and look for things to change.
@pturmel Tell me I'm not all wet here.
-
Can you provide a link for the manual?
Or at least the pages about Detection Method, not just Mode.

ME Station is the PC based Application which lets you run a Factory Talk View Machine Edition executable {*.mer) file on a standard PC.
Your edition of ME Station and your edition of the *.MER file must align.
Using Control Panel - Add/Remove Programs should tell you what edition of ME Station you have installed.
Opening the *.MER with Factory Talk View Studio Application Manager will tell you what edition it is. There is also a tool from RA to determine what revision it is.

3 hours ago, pszczepan said:What do you mean two-phase homing operation. I connected smartstep2 and PLC as it is in manual W450-E1-02 - page 232.
i dont have the manual or a lot of omron servo experience, but the detection method drop down currently is method 1. I'll wager one of the other methods does the find marker , lose marker homing that @pturmel suggested. And you will find that more accurate and repeatable.

It has been a couple of years since I worked with a Fanuc Robot, but let me see if I can answer your question.
First a joint move doesn't move the tool along a path it moves each joint individually.
The joints are different size servo motors and when your program stops them they decelerate to a stop.
They then resume when you ask, so the relationship of each axis to the others will be slightly different than when you don't stop mid flight.
This could result in a different flight path for the tool.

In my 35+ years I've touched Toshiba, Omron, GE, Schneider, Siemens and Rockwell PLCs.
Steve Bailey is correct having a depth of PLC and Industry experience makes you more valuable.
If you're set on staying temp / contract for the forseeable future, then I would focus on Wage, Environment and intangibles and get the best work experience you can rather than worry about what PLC you're working with.
-
I've not seen it before, but were I troubleshoting it I would.
1. Reboot PC and try again.
2. Repair Installation of Control Expert, not reinstall and Reboot, try again.
3. Call Schneider Tech Support and follow their advice.
4. Re-install and try again.
Just my two cents.

I may be mistaken on this, but I believe RSEmulate must be installed for each major firmware revision just like Studio/Logix 5000.
I suspect that someone installed Emulate v20 but not V32.
If you're in support on Emulate it should be a simple download and isntall from the RA website.

Firmware 5.011 has a limit of 400 tags per this manual - https://literature.rockwellautomation.com/idc/groups/literature/documents/rn/2711r-rn001_-en-p.pdf
Not sure what number that would be for your firmware level. And thats Panelview Firmware not CCW.

Currently have TECO software loaded and trying to work on a simple program to control my wood boiler. Currently not planning on using any analog controls - I will use the existing thermostats as inputs. Anyone out there willing to guide me through this?

If you're familiar with Relay Logic then design your Boiler Control as if doing it with relay logic. Then all you need do is what pturmel suggests and substitute the relay logic for plc logic.

Check out Ignition hmi from inductiveautomation.com .
I have heard good things about it's cost to benefit ratio from folks I respect.
And it has drivers for Omron PLC.

I would acquire and familiarize yourself with the Migration Guide. --https://literature.rockwellautomation.com/idc/groups/literature/documents/rm/2198-rm005_-en-p.pdf

You might want to check with your RA distributor. There are DNet Tools that run on a dedicated PC and can monitor the network trqffic and give you an idea why the F71 is occurring.
-
F71 is network loss.
Have you checked the node to node voltage drops.
Also curious as to system age?
Might need to replace a Comm-D card.

Moved this to the Schneider Modicon forum since you're working with Quantum PLC.
Looking at just One Building and One PLC are all your I/O Cards {DigitalIn, DigitalOut, AnalogIn & AnalogOut} in the same backplane Rack?
If not how are your Remote I/O Racks connected to the controlling PLC, {S410, Modbua, something elese?}?
-
Just a few questions to hopefully clarify things for us.
1. Is this running application that broke or is a new installation you're trying to make run?
2. What sub-model of L18ERM are you using is it Series A or Series B?
-
Might Also check the PCDC Pages - https://compatibility.rockwellautomation.com/Pages/MultiProductCompareSelections.aspx?crumb=113&toggleState=&versions=4237,61548,60506
Looks like 1.005 is out and the latest. for the IF16 series A and 2.005 for the Series B

The CompactLogix 1769 Bus is a DeviceNet Bus that runs card to card through side to side connections.
It is not uncommon for the Bus Connections to corrode over time and cause issues of this type.
First troubleshooting step is almost always to power down the unit, seperate all the modules on the din rail carefully and then re-seat them.

Micrologix 1100 - no outputs
in Allen Bradley / Rockwell Automation

The unit you have is relay outputs which are rated 10 mikkion cycles until you read the fine print and see they're actually rated for 30 thousand cycles in some applications. while not likely they all failed they are relays.
