Remark: Framework epitopes = 3 fixed epitopes on the left + number of monitoring modules. (1) In the VMS8000 status monitoring system, the card slot on the left is the power module; the two card slots on the left are redundant power modules, and the redundant power module is optional. If redundant power is not configured, this card slot is reserved Power supply expansion channel; the three card slots on the left are communication modules, and the communication module is also an option. If no communication module is configured, the card slot is a reserved communication expansion channel. The card slot starting with the 4th digit is the function module card slot. (2) For the VMS8000 condition monitoring system, the number of chassis bits = 3 + the number of monitoring modules. | ||||||||||||
