CS1/CJ1W-PRM21 PROFIBUS Master DTM
Section 2-3
Slave Area Tab
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.
Allocation Areas
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.
Module List Box
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).
I/O Mapping Areas
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.
Column
Description
#Addr.
Station address on the network, obtained from the slave DTM.
Index
Index number of the I/O module.
Device
Device name, obtained from DTM.
Module
System generated name.
Size
Module data size, unit of type mentioned in next column.
Type
Module data type, e.g. Byte, Word etc.
Addr
Mapped address area in PLC memory. For example: CIO3200,
equals CIO Area, start address 3200.
