Configuring an Ultra 3000 Drive 213
Electronic Keying
Select one of these keying options for your module during initial module
configuration:
• Exact Match - all of the parameters described below must match or the
inserted module will reject the connection.
• Compatible Modules – The following criteria must be met, or else the
inserted module will reject the connection:
– The Module Types, Catalog Number, and Major Revision must
match.
– The Minor Revision of the physical module must be equal to or
greater than the one specified in the software.
• Disable Keying – Controller does not employ keying at all.
When you insert a module into a slot in a ControlLogix chassis, RSLogix 5000
compares the following information for the inserted module to that of the
configured slot:
• Vendor
• Product Type
• Catalog Number
• Major Revision
• Minor Revision
This feature prevents the inadvertent insertion of the wrong module in the
wrong slot.
ATTENTION
!
Changing the Electronic Keying selections may cause the
connection to the module to be broken and may result in a
loss of data.
Be extremely cautious when using this option; if used
incorrectly, this option can lead to personal injury or death,
property damage or economic loss.
