RPDO default configuration disabled.

[jimlittlefield]

I have some RPDOs that I want configured to start/default to the disabled state. This would involve setting bit 31 of subindex 01 for the RPDO communications OD entry.

0x1404,1 COB-ID = 0x200 + $NODEID

Using the editor changed this to 0x80000200 + $NODEID hoping that the default configuration would have the associated RPDO to be disabled. My application code would later clear bit 31 to enable the RPDO.

After making this edit I was able to save the change, save the device xml file but on attempting to reopen the device xml file I receive an error...

Error parsing node id 0x3+0x80000200 nodes, System.OverflowException: Value was either too large or too small for a UInt16.
at System.Convert.ToUInt16(String value, Int32 fromBase)
at libEDSsharp.EDSsharp.GetNodeID(String input) in c:\Users\jal\Downloads\libedssharp-master\libedssharp-master\libEDSsharp\eds.cs:line 1433

Since COB-ID is UNSIGNED32 I presume that the editor is checking for overflow of the lower 16 bits of the value.

How can I create RPDO/TPDOs which are disabled initially?

Thanks
Jim

Looks like i'm parsing the data at some point into a Uint16 which is incorrect as the field is a UInt32.

The GetNodeID() function which has the job of parsing $NODEID only currently returns a UInt16, which usually makes sense as cobs are 16 bit, however as you found in some cases a 32 bit is allowed so i need to adjust this to cope with the full possible width that it may encounter

Hi Robin...thanks for the fix. I like the checkbox for invalid bit....good convenience feature!
