The self-hosting feature is recommended only for use in FCP270s which are used with 200 Series FBMs. All of the information necessary to reboot 200 Series FBMs is included in non-volatile flash memory on the FCP270. However, the flash memory on the 100 Series FBMs and related products on the 268k fieldbus does not include this information, and they require the workstation host to be present to reboot. More details on the self-hosting feature are available in DIN Rail Mounted FBM Subsystem User’s Guide (B0400FA).

The Foxboro Gas Chromatograph is not supported.

BASEPLATE:The FCP270 is installed on a modular, DIN rail mounted baseplate in a dedicated slot that is keyed for the controller, so other modules cannot be placed in these slots. For further information on DIN rail mounted equipment, refer to PSS 21H-2W1 B3 and PSS 31H-2COV B3.

LED INDICATORS

Light-emitting diodes (LEDs) on the front of the FCP270 module provide visual indication of the:

FCP270 operational status

Communications activity of The MESH control network A and B links

 Communications activity of fieldbus A and B

 Infrared communications activity.

The MESH control network path Tx LEDs indicate which controller is primary as well as the network path it is using; these LEDs are only active on the primary module.
