2.4 C300 Controller
The C300 Controller is constructed using the Series C form factor that employs an Input
Output Termination Assembly (IOTA) and an electronics module which mounts and
connects to the IOTA.
The C300 Controller supports configuration, load and execution of the standard function
blocks. Note that there are a few exceptions defined below.
Exceptions
The following function blocks are not supported by the C300 Controller:

CAB related function blocks other than the Custom Data Block (CDB).
C300 Controller redundancy
The C300 Controller may operate in both non-redundant and redundant configurations.
Redundant operation requires a second identical controller and connecting cables, which
is the typical configuration. The switchover time from the active primary controller to
the backup controller of a redundant pair is less than 500 milliseconds.
C300 Controller block
When a C300 Controller block is added to the Project tree in Control Builder, a graphic
representation of a controller module and its resident function blocks appears as shown in
Figure 2. The function blocks that are contained in the controller support multiple
execution environments. A Control Execution Environment block (CEEC300) and two
IOLINK blocks are contained in the controller and appear under the controller. When the
controller block is configured as redundant, the secondary controller block is added in the
Project tree.
