Axis .data and .diag

Hello,

using AxisInterface, I'd like to get .data.actual.... and .diag.... feedback of the drive(s)

.Data.ActualPosition - WORKS

.Data.ActualVelocity - NO WORK

.Diag.Error - WORKS

.Diag.Message - NO WORK

.Diag.NumberMain - NOW WORK

Why do some work and some not? - see picture

Is it possible to read out the parameter directly, i.e. S-0-0040 or S-0-0084 of the drive(s)?

Working with: ctrlXPLC 1.12.3

Apps:

Motion: 1.12.5

PLC: 1.12.4

Re: Axis .data and .diag

The "Diag" part is empty as long as there is error present at the drive.

The actual values can only be shown as they are present in the PLC. The actual position is part of the cyclic data but in standard the others are not. If you need this actual values, you can configure S-0-0040 and S-0-0146 into the AT.

Of course you can read all drive parameter asynchronous. With the function MB_ReadParameter from the CXA_EthercatMaser library. Or also when ctrlX CORE - DRIVE Connect App is installed via a standard Data Layer read (CXA_DATALAYER -> MB_ReadParameter). See this thread as example.

Re: Axis .data and .diag

OK, found another solution.

Till now, I used IndraDrive MLD for drives, so I am a greenhorn, especially with ethercat...

Now, I know how to config ethercat - data and to add parameters to write/read via ehtercat as well as to implement them in PLC.
