( 7 ) Data Address (PARAM05)
Specify the start address of the data.
The address must be input in decimal or hexadecimal numbers.
Example: When the start address is MW01000, specify “1000 (decimal)” or “3E8H (hexadecimal).”
The range of data addresses may differ, depending on the function code.
The following table shows the valid ranges of data addresses when using a MEMOBUS or Extended MEMOBUS pro-
tocol.
* 1. Request for reading/writing coil or input relay: Specifies the start bit address of data
* 2. Request for continuously reading/writing register: Specifies the start word address of data
* 3. Request for discontinuously reading/writing register: Specifies the start M register number of the address table
Note: Address Table
An address table is used for specifying addresses indirectly in order to indicate discontinuous data. The
PARAM06 (data size) sizes of addresses at the beginning of the M register set by PARAM05 (data
address) are used as an address table.
When reading, specify the remote station's address to read for the data addresses 1-n. Read values are
stored locally according to the data addresses 1-n.
When writing, data stored in the local data addresses 1-n is picked up and written into the remote sta-
tion’s data addresses 1-n.
The address table used when discontinuously reading/writing registers is as follows:
