Commissioning Commissioning is the process of writing the LONWORKS addresses, the binding information and the configuration to the Excel 10 Controller. E-Vision is the tool used to perform these activities, as described in Appendix B. Job Commissioning The CARE database that is generated for the Excel 10 FCU Controllers and associated Zone Managers contains information concerning interrelationships and network identifications. For this reason, it is mandatory to commission (assign ID and download) all Excel 10 FCU Controllers and the Zone Managers from a single database. ® containing its Neuron ID number. This ID number is on a removable sticker on the side of the W7752 housing or on the adhesive sticker on the top of the W7754 housing and can be typed in manually. E-Vision is used to perform both methods (see E-Vision User Guide). Configuring the Zone Manager The Q7750A Excel 10 Zone Manager sends a one-time LONWORKS message containing its 48-bit Neuron ID after any power-up WARMSTART or when the Excel 10 Zone Manager is reset by pressing the reset button. IMPORTANT Pressing the reset button on the Excel 10 Zone Manager causes all application files in the Q7750A, including the C-Bus setup, to be lost. [. . . ] Bug Fix Number: Network variables are unchanged. A change to the algorithm, network interface, or physical input/output subsystem was made that does not affect compatibility with other nodes or the equipment controlled by the node.
