(Supports Hot Swap and Device ID)
Part Number
FB-700 (Fieldbus Module)
Description
The FB-700 is a Fieldbus interface card for the LC700 programmable controller. It integrates the
discrete control capability of LC700 with Fieldbus.
The Foundation™ Fieldbus interoperability feature assures that the FB-700 will work perfectly with
any other FF device, even from manufacturers other than Smar.
The FB-700 is directly attached to the LC700 backplane. The LC700 accesses it as a regular I/O
card, which supports many digital and analog I/O points mapped to the FB-700 function blocks. For
proper operation, both CONF700 and SYSCON should configure the card.
