Additional Module Parameters
Additional module parameters vary, depending on the module type. Some modules have only a
few parameters. Others have several. The additional parameters that must be configured for
more complex modules are explained in the individual module documentation.
Carrier Type:
The carrier on which a VersaMax module is installed is chosen to meet the needs
of a specific application.
Report Faults:
Specify whether or not the module will report faults to the PROFINET Scanner.
DC Filter Select:
This field selects additional filtering time for the module’s DC inputs to
compensate for conditions such as noise spikes or switch bounce. During operation, a filter time
of 0ms, 1.0ms, or 7.0ms will be added t
o the module’s basic input on/off response time.
If this is set to 0, no additional filter time will be added to the module’s basic maximum input
on/off time:
Basic On-Off Time Module Types
0.5ms
IC200MDL631 / 632 / 635 / 636 / 640 / 650,
IC200MDD840 / 842 / 843 / 844 / 845
0.25ms
IC200MDL643 / 644, IC200MDD851
Outputs Default / Hold Last State:
When the module has outputs, this field specifies how the
PROFINET Scanner will handle the module’s output data if it loses communication with the IO-
Controller
. Select either Hold Last State or Default Value. This setting applies to all the module’s
outputs. If Default Value is chosen, default values can be set up on a per-point basis.
Note:
VersaMax analog modules latch their last outputs when configured for Hold Last State
and hold that value as long as field power remains on the module.
In contrast, discrete modules transition to module defaults of zero, even if Hold Last
State is configured, when they lose connection to the PROFINET Scanner.
Default Output Values:
If the module has discrete outputs, a default value of 0 or 1 can be
selected for each output. Outputs without a configured default value will default to 0.
All VersaMax Analog modules except MDD841 and ALG331 support only a default Analog
value of zero.
Note:
Unlike other VersaMax Scanners, the PROFINET Scanner does not contain input default
actions and default values. In PROFINET, these settings are part of the IO-Controller
configuration.
