DataLayer: DL_TYPE_MISMATCH reading node with PLC

[alink]

Hello,

I try to read out node 'diagnosis/get/actual/list/amount-errors' into PLC to check if there is one or more error in CtrlX to confirm, get more info, and so on....

I use this code like in online help:

Decleration:

Code:

When executing an Access_Error 'DL_TYPE_MISMATCH' follows.

Error description does not help much, at least to me.

As I read in description type is set by node? So why wrong type, don't understand.

Any ideas what's wrong, thanks for help

Types are check in both directions reading and writing. The value you are reading is a UINT64 and your node gives you back a value of that type. You attached a string variable to the output, so the function block says type is mismatching I cannot put the data there.

General documentation for ctrlX Data Layer errors see here.
