External Host Application
The application residing on the external host microcontroller has
direct access to the local PLC memory over I
nication enables the host controller to instantiate several PLC
functions by reading or writing to the appropriate memory
locations in the PLC chip. Thus the host application can
configure the CY8CPLC10, read status and configuration infor-
mation, and transmit data to remote Powerline nodes. Refer to
the CY8CPLC10 application note (AN52478) on how to build a
PLC command set using the CY8CPLC10 memory map. The
device has a dedicated pin (I2C_ADDR) for selecting the I
slave address while communicating with the external controller.
The two I
The PLC commands can be classified into two types based on
which Powerline node they are designated to: local node or
remote node.
Local Commands
These commands act solely on the attached local PLC device.
No transmissions are sent over the Powerline to a remote PLC
device when executing these local transceiver commands.
These commands are used for configuring the local PLC node
such as setting the local logical address or reading the status and
configuration information.

Remote Commands
These commands initiate transmission over the Powerline to a
remote PLC node. These commands when instantiated over I
enable the host application to send and receive data over
Powerline. Along with the data payload, the I
carry additional information for the Powerline transmission to a
remote node:

EEPROM Back Up for Remote Reset
The device also has an EEPROM to back up Memory Registers
0x00-0x05 and 0x30-0x32. When the device is reset remotely by
the SetRemote_Reset command (described in
its memory map and loads from the EEPROM and returns to idle
mode.
