Memory Map And Controller Assignments - Panasonic SC-HG1-C User Manual

CC-LINK Network Communication

4-4 Memory map and controller assignments

● This product can be connected to a maximum of 15 controllers (one master controller, 14 slave
controllers).
● To enable data communication with connected controllers (master unit and slave units), the
memory map contains a communication register for each controller.
● The controllers are assigned to register positions in the memory map based on the position
in which each is connected.
The controllers are automatically assigned in the memory map starting from the master unit
and continuing in order from slave unit 1. The order cannot be changed.
Example: Mode 3 remote register RWr
