What is Black Fabric® Communication?

March 10, 2020 |  Kate Pinckney

The Black Fabric® communication consists of galvanically isolated, full-duplex communication channels. One or two channels are dedicated to the SPM modules while the remaining channels are dedicated to SIO modules. The number of channels available for controllers, SPMs, and I/O modules is dependent upon the BMI and Controller Type.

Each SIO module has the connections to a Controller. Each SIO module has a dedicated full-duplex four-wire bus connecting the Controllers and SIO modules. This allows a Controller to receive SIO data directly into its registers.
