The entire bus system is duplicated,There are two master stations and two remote bus channels.Every individual multi-purpose processing station is connected in parallel to both remote bus channels.As a result,data transfer can take place only on one of the two remote bus channels at a time.
The prcessor of the master station (consistingof the modules 88VA01/VA02,88 VP01/VP02，88VT01/VT02) handles the data communication on the connected bus system,However,it is only authorized to do so when permitted by the higher level coupling module 88 VU01.
The main task of the coupling module is to grant the master station processor permission for data communication or to withdraw such permission.Normally,one complete system cycle is performed by every master station in alternate succession(i.e.,complete dataexchange from and to alstations connected to the bus system).The exchange of information between coupling module88 VU01 and the master station processor is performed by way of the master station bus inter-face, First,the coupling module switches off signal MRST(Master Reset).Now the processor can ask the couping module permission to start datatransfer on its bus system.The coupling modulethen grants such perission(aS "START CYCLE"_command),authorizing the processor to performthe system cyce.The processor signals the beginning of this cycle to the coupling module (as"BEGIN CYCLE"-annunciation).
Application:
The couping module for monitoring station is used within a PROCONTROL master station.
The processor of the master station exchanges information with the coupling module.It receives permission from the coupling module to carry out data transfer and reports the end of the transfer cycle to the module.The release of data transfer is dependent on certain conditions in the total system.
The module is available in two versions :
88 VU01-E/R1010:Equipped with function PROM foruse in master station A
88 VU01-E/R1011:Equipped with function PROM foruse in master station B
