7.5 How to Use Data Mapping
When this communication method is used, 16 types of data (mapping data) can be specified as desired for
the Z-TIO-G module, and read/write can be performed continuously.
Data range
Register address to specify mapping data 1000H to 100FH
Register address to actually read/write data 1500H to 150FH
Register address of data which can be mapped Refer to 8.2 Normal Setting Data (P.8-3) and 8.3 Engineering Setting
Data (P. 8-9).
For the data mapping address list, refer to the 8.5 Data Mapping Address (P. 8-24) .
[Example]
Mapping the CH1 data “Measured value (PV), Manipulated output value (MV) monitor, Event 1
state monitor, Event 2 state monitor” of a Z-TIO module to register addresses 1500H to 1503H.

1. The register address, “0000H” of the Measured value (PV) to be mapped is written to register address
setting 1 (1000H).
2. The register address, “000DH” of the Manipulated output value (MV) monitor to be mapped is written
to register address setting 2 (1001H).
3. The register address, “0025H” of the Event 1 state monitor to be mapped is written to register address
setting 3 (1002H).
4. The register address, “0029H” of the Event 2 state monitor to be mapped is written to register address
setting 4 (1003H).
5. The assignment of the register addresses from 1500H to 1503H from/to which data is actually
read/written becomes as follows.
Register address
Name
HEX DEC
1500 5376 Measured value (PV)
1501 5377 Manipulated output value (MV) monitor
1502 5378 Event 1 state monitor
1503 5379 Event 2 state monitor
Write
High-speed communication is
performed by reading or writing data in
the consecutive register addresses from
1500H to 1503H.
