APPLICATIONS WITH MASTER AND SLAVE CONNECTION
Figure 4 - Master/Slave application
In several applications (such as robot cells, AGVs, etc.), there is a need to monitor sev-
eral zones that are not visible from just one point, e.g. two opposite sides of a rectangle.
In such cases, the use of several scanners is required. However, there may be just one
safety function (i.e. the dangerous movement that must be stopped when someone is
detected inside the safety area).
The Laser Sentinel can effectively solve this situation: irrespective of the use in horizon-
tal or vertical position, up to 4 Laser Sentinel units can be easily connected to each
other through Ethernet-based safe communication bus, working as a single system.
Only the Master Unit receives power, has inputs and outputs onboard, and must be con-
nected to a PC in order to configure the whole system. The Slave Units (or Remote Units)
are connected to the Master with a single cable that also provides them with power.
The synchronization of the four scanners is an integrated function. There is no need for
external control units.
