88VA02E ABB Control Module for Transfer Procedure

The control module for transfer procedure is part of the entire master station processor (comprising the modues 88VA01/VA02, 88VPO1/VPO2 , 88VT01/VT02).  As an"auxiliary module" of the processor, it performs certain subfunctions of the entire master station program. However, each of these subfunctions is only executed after aspecific command from processor modue 88VP01/VP02.The comands resuit from the command fields of the 48-bit data word in the program memory (see module description "Master station processor module 88VP01/VP02"，GKWE 705180). The commandsare transferred in coded form via the general-busand are decoded on the modue (the decoders are not shown in the functional diagram).
In the following, the most important functional blocks are specified and their functions with in the entire program of the master station processor module are described (see also“Functional diagram" ).
