C300 Controller execution environments
The C300 Controller supports three Execution Environment (EE) function blocks. One is
the Control EE block, (CEEC300). The other two are I/O Link blocks, (IOLINK). The
IOLINK blocks in the C300 support connection and communication with all Series 8 I/O
modules.
CEE function block
The CEEC300 block provides an execution and scheduling environment in which
Control Modules (CMs) and Sequential Control Modules (SCMs) execute user-
configured control strategies. Existing control strategies can be ported to a C300
controller, although manual editing of these strategies is required to support the C300
controller configuration. The CEEC300 block contains a peer-to-peer communications
layer which is used to communicate between other controllers.
