I/O Mapping Areas

The Slave Area tab displays the mapping of the I/O data from/to the allocated
slave devices on to the PLC memory areas. The mapping can be made auto-
matically, but can also be changed by the user, before downloading.
The Slave Area tab is shown below. Only the Output Allocation tab is shown.
The Slave Area allocation tabs define how the I/O data of each of the slave
devices is mapped on to the PLC memory. The Slave area tab contains two
tabs, one for Output Allocation and one for Input Allocation. Each tab contains
an overall module list, showing all the output or input data per slave, along
with the Module names, sizes, data types and start addresses. This data has
been transferred to the Master DTM by each of the allocated slave DTMs. If
no slave devices have been allocated, or configured, the list will be empty.
The Module List Box list contains the following information (refer to figure
above, the table applies to the lists in the Input and Output Allocation tabs).
Column
#Addr.
Index

Each Output/Input Allocation tab also contains two areas on to which the I/O
data can be mapped. The areas will in turn be mapped to the PLC memory.
By default all data is mapped to Area 1, in order of ascending slave device
address.
Note 1. When mapping, the modules are copied from the module list to the map-
ping Area and not moved. This means that the module list acts as a re-
source for the two Mapping Areas, below the module list.
Station address on the network, obtained from the slave DTM.
Index number of the I/O module.
Device name, obtained from DTM.
System generated name.
Module data size, unit of type mentioned in next column.
Module data type, e.g. Byte, Word etc.
Mapped address area in PLC memory. For example: CIO3200,
equals CIO Area, start address 3200.
