
Revision. Revision is divided into major and minor revision values.
The major revision indicates the revision of the interface to the module.
Valid values are in the range 0 to 127. The minor revision is used to
indicate the firmware revision. Valid values are in the range 0 to 255,
with 1 being the default value. As releases occur, these numbers will be
incremented.

Address/Host Name . Enter the IP address or host name for the
module.

Electronic Keying. This option prevents the inadvertent connection to
a module of the wrong type. The following fields are checked for either
an exact match, or a compatible match:
-
Vendor.
-
Product Type.
-
Catalog Number.
-
Major Revision.
-
Minor Revision.
During initial module configuration, select one of the
following keying options:
Exact Match. All of the listed parameters must
exactly match or the newly installed module will
reject the connection.
Compatible Module. The following fields may match
as follows:
Major revision. Field does not need to match
as long as the module in the chassis is
greater than, or equal to, the software’s
configuration’s major revision.
Minor revision. Field of the physical module
must be equal to, or greater than, the one
specified in the software.
DANGER Hazard of personnel death or injury, damage to property, or
economic loss if keying is disabled.
Disabling keying could lead to a module being incorrectly
connected to a programmable logic controller, resulting in loss
of connection and/or improper controller function.
When using this feature, exercise extreme caution.
-
Disable Keying. When selected, the controller employs no
keying to check whether it is connected to a compatible
module.
