Invensys Triconex 3721 Module

Triconex 3721 Brand New In Stock

Information

The TCMI connects directly to an Ethernet port of the Tricon Communication Module (TCM) in the Tricon Safety Manager. The TCM implements the TSAA communication protocol on Ethernet networks for communication with the Tricon controller. TSAA Protocol is a messaging protocol used in application programs that read and write data to the Triconex controllers and is utilized by the TCMI. The TCMI requires the use of a pair (two; one-part number 4351A and one part number 4351B) of TCMs in the Triconex system. The TCMs connecting to the TCMI must reside in a single Triconex System logical slot and shall occupy the left and right module physical slots (which comprise a single logical slot). At least 1 port on each of the TCMs is required to configure a redundant TCMI pair. If empty ports are not available in existing installed TCMs, then new TCMs must be installed.
