Definitions of Active and Passive Hardware Modules
This section details the definitions of the hardware modules.
Active Versus Passive Module
An Active module is defined as a module that sends or receives specific commands and
checks. The control communication is done via the BUS serial protocol for all active devices.
A typical example is the motor for the X-Axis which has to be accelerated to a certain speed
and stopped after a defined travel distance. The motor records the position at every point of
its trajectory and is reported back to the processor via the BUS using the X-motor (Servo
motor X-axis).
Another example is an Agitator where the temperature and motor for sample agitation have to
be controlled and monitored.
A Passive module is a static device. Typical examples are non-temperature programmable Tray
Holders, a TR Station, or a Standard Wash Station.
You can easily distinguish the difference between active and passive devices by checking for
any serial connectors at the device. See the example in Figure 24 , which shows the passive
module TR Station on the left, and the active module ATC Station for three Tools on the
right. Every Active Module has two connectors for daisy chaining to the next module.

Example of Passive and Active Modules
At the level of the RSH Firmware, it is important to understand other differences between the
two classes of modules:
