DFB Get PROFIBUS Standard Slave Diagnostics - M340
MNETDPV1_BASICVAR_PB_SLVDiagnostics Variables - M340
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
Out - TimeOut 1
16-bit Integer
Used to hold the amount of time in milliseconds to wait
for a response to the Modbus TCP/IP command before
assuming a communication error has occurred and
setting the In-MessageError status bit
Out -
GetPBSlaveDiagnostics 1
Single-bit
Boolean
This is the bit your control and sequencing logic will
use to trigger a read message that will retrieve
PROFIBUS slave diagnostic data. Set this bit to one
(1) whenever no other messages are active and when
you want to update the MNETDPV1_SLVDIAG data
variables.
Out - MailBoxData Multi-variable
nested DDT For details, see Modbus DDT (page 98).
In - MessageDone 1
Single-bit
Boolean
The DFB will set this bit when the Modbus TCP/IP
response is successfully received and the PROFIBUS
cyclic input data variables have been updated.
In - MessageError 1
Single-bit
Boolean
The DFB will set this bit when the Modbus TCP/IP
response is not successfully received. When this bit is
set, it indicates your control and sequencing logic
should retry the command.
