7.4 Data Map
If you add or delete a function module, or change the arrangement of the modules, or replace a
module with a different model, be sure to perform “Module initialization (Register addresses:
02BFH)” (P. 127, 153) before setting the data.
“Module initialization” stores the new module configuration in the H
-PCP-J
module.
If data is set before “Module initialization” is performed, the H
-PCP-J
module will set the
previously stored initial data of the old modules in the new modules, which may cause
malfunction.
7.4.1 Reference to data map
This data map summarizes the data addresses, channels and names that can be used with Modbus
protocol. For details on each data range, see
7.3.3 Communication data list
(P. 120)
.

Address:
Address of data is written with hexadecimal number.
Characters in ( ) are decimal number.
Addresses in holding registers used for the Modbus protocol start with 0, but generally
those for the PLC, SCADA and display panel start with 40001.
Therefore if the holding register is specified by the PLC, SCADA and display panel, 1 is
added to the address (in a decimal number) described in the data map and also 4 is
affixed to the 5th digit * of the same address.
* Differs depending on the Model and driver used.
Example:
