Controllers / Re: Output Configured for both/either Sinking or Sourcing
« Last post by Lukey on May 30, 2024, 09:59:32 AM »
I've managed to get the pin to function as both sink and source with out issue on the PLUS+1 Hardware.

Issues arises with the relays I am driving externally.
As the configuration is basically 2 relays in series, the coil holding voltage once energised is high enough that the relays do not energise.
24V system, 2 relays in series, sees 12v across each coil, this is enough for them to energised.

I believe I can you some kind of diode configuration but I haven't worked out which yet.

Displays / DM1200 CAN connection protection
« Last post by BRIan on May 30, 2024, 03:05:06 AM »
Any idea what the protection is on the CAN pins? Reverse polarity, voltage, short?
We had instances where some CAN sensors (24V) didn't have an earth and this trashed the DM that was on the same CANbus.

Hi There,

Does any one knows if the ethernet function on the DM700 or DM1xxx now works?

and how to use that of course.

Danfoss already sells the DM700 with the ethernet port :-X :-X

Thank you

Displays / DM700 / DM1000 Ethernet Server Connection
« Last post by Mike_vd on May 29, 2024, 04:47:37 PM »
Good Morning Team,

Currently considering a project that utilizes an DM700/DM1000 for logging of data and then sending this data off to a server via ethernet at the press of a button. No need for constant communication. Example once a test cycle has concluded to send the results off to a server for record.

Couple of questions:

1. Firstly is it possible?
2. Does anyone has experience with this?

Any insight/expertise would be greatly appreciated.

My vote would be probably CANOpen, it gives you the flexibility to setup your devices to respond individually to SYNC messages.

For example, if you have a device that isn't required to have fast data response, configure that to respond to every 20 (or whatever) SYNC messages. The critical devices would be set to respond every SYNC message.  Using this method can help maintain your bus load.

Hi Lukey,

Is the output pin on a PVG type?  They can sink or source in this mode, but not sure of the current availability in this mode.

Displays / Re: Data logging limitation
« Last post by Lukey on May 21, 2024, 04:25:21 AM »
Mike I am using the applog for daily logging on a drill rig, logging at 1 second intervals with more that 20 points.

The work around I have is that I create 1/the 1st point that is my 'header' of the CSV file, using Commas as my delimiter between the 'points' I am logging, this 1st point is written only once at the beginning of the log.
This is done so that when processing the CSV in excel by using 'Text to Columns' feature, each column of data then has a header for reference.

The second point is a STRING of all the points that I want to log, using a POU and instruction CONCAT, I merge all my inputs together, inserting a comma delimiter between (for the reason above), and then outputting a STRING to the applog
This 2nd point is written at 1 second intervals.

I haven't found any character limitations using a STRING in this method.

See the screenshots, my 2nd point is actually 3 STRINGS, again separated by a delimiter of a comma for processing in Excel.

I also have the CS500 in my project, yes it is completely useless for applogging/datalogging, as it can't receive strings, signed values and is limited to 31 byte messages (U31).
PLUS+1Connect Reports and Charts don't have the capabilities of the applog. Plus+1HelpDesk has told me it's in the pipeline, don't hold your breath.

Displays / Data logging limitation
« Last post by Mike AA on May 21, 2024, 01:33:12 AM »
I am using the applog data logging ability to frequently record machine data, unlike most who use the logging for errors and alerts we are using it for daily logging. I have nearly 30 data points that I need to log. I know about the 20 point limitation and it really hinders data analysis and makes merging data much more time consuming. Has anyone had any luck on a danfoss work around doing more than 20 points? There must be a reason for the 20 point limitation since you can log data until you run out of memory. MY current work around involves having 3 machine data logs which I still need to further manipulate taking more time.

I am using the applog like was discussed in this thread
https://www.plus1forum.danfoss.com/index.php?topic=927.msg2884#msg2884

I am investigating the data logging properties of the CS10 and CS100 but they appear to be very limited to non existant.

I started looking at external data loggers but they add more complexity by needing to convert the log file.

PLUS+1 GUIDE / Re: Guide Text Box Tab

Hello Scott_MARL,

I did a quick test with similar texts in v2024.1.5 and it seems to work.

Can you do some test with the latest version of PLUS+1 GUIDE as well?
If you see the same issues please report it to plus1helpdesk.danfoss.com


Thank you.
