ABB 216VC62A Processing unit
Description:
The 216VC62a is used both as a processor and as an interface to the interbay bus (IBB) in the substation monitoring system (SMS) and the substation automation system. The available 
communication protocols are:
SPA BUS
LON BUS
MCB interbay bus
MVB process bus
The 216VC62a has a 25 pin connector on the frontplate for the serial interface RS-423A, CCIT V.10. Data transfer takes place vie a unbalanced cable at a data transfer rate between 1200 and
19200 Baud. The signal level for the 216VC62a is approx. ± 4.5 V.
The PC interface (RS-232C) is initialised and appropriately set to communicate with the RE. 216 by the software.
The supply to the memory in the 216VC62a is maintained in the event of an interruption by a gold condenser so that the event list and disturbance recorder data remain intact. The disturbance
recorder data can be read via either the interface on the front of the 216VC62a or the object bus. The data can be evaluated using the “EVECOM” evaluation program. The internal clock of
the RE. 216 can be synchronised via the object bus interface of SMS/SCS systems or by a radio clock.
