Description of the interface module parameters

DP interrupt mode
This parameter allows you to choose between DPV0 and DPV1 mode of ET 200pro. If DPV1
is set, the system generates interrupts (diagnostic, process, swapping interrupts).
Requirement: The DP master also supports DPV1 mode.
Diagnostic interrupt
This parameter allows you to enable or disable diagnostic interrupts. Diagnostic interrupts
are only generated when ET 200pro is operating in DPV1 mode.
Hardware interrupt
This parameter allows you to enable or disable hardware interrupts. Hardware interrupts are
only generated when ET 200pro is operating in DPV1 mode.
Swapping interrupt
This parameter allows you to enable or disable swapping interrupts. Swapping interrupts are
only generated when ET 200pro is operating in DPV1 mode.
Operation with preset <> actual configuration
If this parameter is enabled and
● you hot-swap an electronic module, this will not cause a failure of the ET 200pro station.
● the preset and actual configurations do not match, ET 200pro can still exchange data with
the DP master.
If this parameter is disabled and
● you hot-swap an electronic module, this will cause a failure of the ET 200pro station.
● the preset and actual configurations do not match, ET 200pro cannot exchange data with
the DP master.
Identifier-related diagnostic data
This parameter allows you to remove identifier-related diagnostic data from the diagnostic
frame. This action reduces the length of the diagnostic frame by the length of identifier-
related diagnostic data (4 byte).
Module status
This parameter allows you to remove module status data from the diagnostic frame. This
action reduces the length of the diagnostic frame by the length of the module status data
(9 byte).
