C200HW-PRM21 PROFIBUS Master DTM
Address Table Tab
Memory Layout
Note
52
Note The mapping in the Address Table tab does not define the mapping on to the
PLC memory areas. This is done by making the appropriate settings in the
unit's DM areas, which are described in the C200HW-PRM21 Operation Man-
ual (W349-E2-@).
The Address Table tab contains an overall module list, showing all input and
output data per slave, along with the Module names, sizes, data types and
start addresses. This data has been obtained by the Master DTM by each of
the allocated slave DTMs. If no slave devices have been allocated, or config-
ured, the list will be empty.
The Memory Layout box list contains the following information.
Column
#Addr. Station address on the network, obtained from the slave DTM.
Device Name Device name, obtained from DTM.
Module Name System generated name.
IType Defines the Type of the Input:
• IB: Input Byte type
• IW: Input Word type
IAddr (Word) Start Address of the Input data of the Module, relative to the start
of the internal memory of the Unit, containing the Input Data block.
IAddr is expressed in Words.
OType Defines the Type of the Output:
• QB: Output Byte type
• QW: Output Word type
OAddr (Word) Start Address of the Output data of the Module, relative to the start
of the internal memory of the Unit, containing the Output Data
block. OAddr is expressed in Words.
1. Modules consisting of one single byte will occupy a full word address.
2. A total of up to 512 Input bytes and 512 Output bytes can be mapped on
to the Unit's internal memory. Therefore, the maximum permissible ad-
dress value is 255 (Words). However, the C200HW-PRM21 to PLC mem-
ory mapping is limited to a total of 300 I/O Words.
