Interoperability
If a device is to be replaced with another manufacturer’s device, or a device
from the same manufacturer but from a different model series, this
replacement falls under the category of interoperability.
Interoperability will require a complete recreation of the control strategy
function blocks in the failed unit. The existing blocks in the failed unit need to
be deleted and then replaced by appropriate function blocks in the existing
strategy. The resulting strategy will then require a complete download of the
entire network.
Interchangeability
Interchangeability is the ability to replace one failed device with a good device,
provided that the devices are from the same manufacturer and class. In this
case, replacement can be accomplished by moving blocks from the failed
device to the replacement device. The replacement device can then be
downloaded without any need to edit the strategy or download the entire
network.
If interchangeability is an option, there are two possible ways of accomplishing
it:
