Write Mapping:
The write process data represents cyclic data sent from the AC20 to the PLC, this is mapped into the table
Option Comms Output Mapping.

Note: String-type parameters cannot be mapped.
Default Mapping: The process data mapping will contain a factory default mapping. The default mapping
may be overwritten if required.
Assembly mapping object instance
The process data is represented as dedicated instances in the assembly object (CIP), the Assembly object
uses static assemblies and holds the Process Data sent/received by the master. It allows data to and from
each object to be sent or received over a single connection.
Process data “Input” will produce data on the network and process data output will consume data from the
network.

Cyclic Data Exchange
Cyclic data exchange will occur when a Class 1 connection is established (active or idle). However, the
read process data will only update the mapped parameters when in the PROCESS ACTIVE state.
On a transition into the PROCESS ACTIVE state all read process mapped parameters will be updated.
When in the PROCESS ACTIVE state, the read process mapped parameters will all update only when a
change in the read process data occurs.
