This variable structure is the one to use with your control and sequencing logic

when you want to send a request to read standard PROFIBUS slave diagnostic

data.

Variable Name Size/Type Description

GetPBSlaveDiagnostics

Single-bit

Boolean

This is the bit your control and sequencing logic will

use to trigger a read message that will retrieve

(1) whenever no other messages are active and when

you want to update the MNETDPV1_SLVDIAG data

variables.
