The settings need to match what the PLC serial port is configured for. Can you post these from your .cxp file? One suspicion is that you are trying Hostlink from the simulator, yet the PLC is configured for NT link to match the NS...? The PLC needs to be configured for hostlink to match the mode you are trying to connect with from the simulator.

Just checked my install as well, & both those options are there!! As well as the project specific transfer settings! :-2 Well done Omron for making these simple changes to make our jobs easier.

He is trying to configure the AB to consume the data from the CJ2. He cannot change the Omron addressing as it seems that this machine has its own mini network, that all require the 192.168.0.xxx addressing. Best option is to get another ENBT for the L62. That way, the OEM configuration is still the same & the plant structure does not need to be modified either.

Simple thing, is there a way to display the new DTL the same as the old one? I really am used to pictures & seeing everything, not that I have to search is confusing me a wee bit I was so used to the old format...

Are the AB & Omron PLCs on the same subnet? What are the IP address's of each? To consume in the AB, all you need to do is create the generic profile with the correct IP & tag structure and it should work..

Peter, You really need to provide a picture of your layout. If I understand correctly, you are trying to measure the width of material based on time? There are better ways to do this more accurately. Where do you buy your Omron hardware from, are they able to provide support? Interrupt modules can be configured to execute a set task in the PLC when the input is activated, up to 16x tasks. This information is all in the manuals, do you have them? Is the 'pulse' the same device? Are you sure that the fibre sensor is seeing the change of state? If yes, then is the PLC seeing the COS?

We had a similar issue with an NS. Initially our suspicion was that itwas due to using the data-logging feature to CF, but I now wonder if it was due to the web server also being enabled. PMCR, have you had a NS running with web server for long periods of time, whilst also logging to CF? I wonder if it was specific versions that may of experienced these issues?

REPEAT Move(100) WA(2000) Move(-100) RETURN I suspect you may have other problems though

I will PM you my email address.

There is no difference in that programme to what I posted? You need to post a copy of the trace from CX-Protocol, as well as a wiring diagram showing all connections & switch settings, including PLC unit no's.

Yes.

Hex #10 = Decimal 16, which is preset multiple registers, so Function 10 should work. It may be worth doing what PMCR suggests re the address offsets, but I am pretty sure with Schneider that these address's would be correct. You should definitely be getting a response. Question: Have you programmed the ATV31's to be the correct Node address's, 1 & 2? I would be starting with just a single drive first, & make sure that will work. The trace data will be useful as well.

Cannot be done that I know of. Easier option would be do create the password in the PLC, then use a bit to interlock whatever you want in the screen. This way the PLC & NS can change passwords, just not using the NS security features.

I mentioned contiguous. To me, this means that the registers you are wanting to read are one after the other; 3201, 3202, 3203 etc. Perhaps consecutive would of been a better term. In the ATV31, they are consecutive. What this means is that it may be more efficient to create a custom Protocol Macro for the ATV31's. This would reduce the PLC code required for the Easy Modbus & free up some memory. To begin with though, lets see if you can get the Easy modbus functioning to a single inverter first. Another thing to check, are you using a single PLC for this, or something that is doing other tasks? Reason is that you need to be very careful that your other tasks do not use the same IO that the Easy Modbus does. if this happens, things will not work as expected!

If you downloaded the Easy Modbus from the downloads section, you would of got all the other information as well, including the coding sheet & instruction example for the MX range. Attached is a quick knock up of what I would do.. There is the coding sheet, then the setup of this in the PLC file, as well as some example code for starting/stopping the inverter.. There are 2x Read Commands & a single write command per unit (2 in total), reading/writing 2x registers each message. NOTE: This is untested, normally I start with a single unit & get the basics of what I want working, then duplicate through the rest... You may want to not use the example start/stop code as this may not be correct, you will have to test yourself for these particular drives.. ATV31.zip

With the Modbus Easy master from PMCR, there is a excel coding setup sheet, that can also generate the ladder code for address setup. I normally install the ladder as you have posted in its own task, then create a routine in another task called setup. In here, I paste the generated setup code. Did you download the excel setup file? I will have a look at the ATV31 manual later & try & post an example back.

Bob, It is a CP1L, it does not have to be enabled just the range code written & the 200ms delay implemented.

Can you post or PM what you have done so far? I've found the project that I did, pretty sure this start/stop & speed control as well as current but will confirm later. I'll try & find the ATV31 manual as well. The project I did didnt use easy Modbus, but that is ok..

Yes, but the manual also says 4-20/1-5v...

Peter, Have you looked at the Easy Modbus download yet? There is a help file (albeit for omron inverters), but all you need to do is change the registers you want to read from & it should work. Do you know the parameter no's that you are wanting to read from the ATV31's? Are they contiguous? If not, then Easy Modbus is your best option, if they are contiguous, then maybe customisation is more efficient. How many inverters will you connect to each serial line? Note: Jojo is using the new ATV312, whereas you have the ATV31. The 31's are the old Toshiba drives, whereas the 312 are schneider, so the parameters sets/no's will be completely different. I will try & dig out the 31 PMCR that I did a few years ago.

What range do you want the analogue inputs to be setup for? +/-10, 0-10 or 1-5? I would recommend you setup for 0-10 if the source is a voltage. But, since it appears you have it setup for 1-5/4-20mA range, I would suspect that you need to link the Vin & Iin terminals. Also, as per the manual, you should wait min 200ms before trying to read after power up. I see you have used the 1sec bit, I would also put a timer in series with this that takes 200ms after power up to become true.

Maybe have an external time clock that switch's an input at midnight for the sync?

There are string conversion instructions that convert HEX data to ASCII formats (ASC/STRx). I have done this for multiple applications/purposes. One is for an alarm log that has DateStamp & code, the other for PLC based data logging for later review. Bear in mind, the converted data takes up more memory, so you may need to think smart...

This is a sort of example of what happens, the Green U means Update, whilst I think the Yellow O means Old. There is also a N, which I assume means New

Compare for what Bob, do you mean the version in NS & PC? There is one sort of, you can see what screens are different when connecting. Not sure what other HMI's offer..?
