SIMATIC FS600 Laser Scanner
a = Fuse 1.25 A
b = Restart button
c = Peripherals, e.g. ET200M with failsafe signal subassembly
d = Further processing by a failsafe PLC, e.g. SIMATIC S7-300F
Fig. 8.3-1:
All switching functions in this sample connection are controlled directly by the PLC.
The changeover of 4 zone pairs is achieved by way of the inputs X1-4 (FP1), X1-6 (FP2),
X1-7 (FP3) and X1-8 (FP4).
For applications in which the scanner must be separately enabled for its detection zone,
the signal can be given either by the machine controls or by connecting a command unit
for restart interlock. The SIMATIC FS600 Laser Scanner itself must be configured using
the "SIMATIC FS600 Parameterization Software LS4soft" user program so that the
operating mode "with restart interlock" is active.
