6F2T0200 (0.15)GRE200 (1,2)- 508 -5.2.2 1/2 size case(i) Unit structureThe unit structure is shown in Figure 5.2-2 (a). A unit is made of VCT, CUP and BIO modules.They are jointed using HMI front panel. A case will be used to cover the unit. UBS port isprovided for the maintenance.(ii) Rear viewFigure 5.2-2 (b) and (c) show the rea view and schematic diagram of the rear view. VCT ismounted at terminal label “VT”. IO module “IO#1” is mounted at terminal labels “T1 and T2”†,whereas the other IO modules are mounted at “T3” and “T4”. Communication modules aremounted at terminal labels “C1, C2, and C3”‡.VCTT1 VCC1 C2C3IO#1-1Terminallabel T2IO#1-2T3T4IO#2IO#3FG terminalShort wires Ground terminalProbe[IO#1]T2 T1 VCC1 C2EFGC3T3T4[IO#2][IO#3]Slot identifiersVCT BIO CPU BIO TerminalsBIO BIOCasea.
