  • Page 3 ™ Fieldbus configuration tool. Function blocks provide logic such as AND, OR, NAND OUNDATION etc. as well as latches etc. Link master capability allows the DC302 to work as a backup LAS for greater availability of network communications. The DC302 may be installed close to the sensors and actuators, thereby eliminating long wire runs and associated marshalling panels and cable trays for the conventional I/O, with subsequent savings further reducing overall system cost.
