Changing the block size:
X Close all applications.
X Close the CoDeSys gateway server.
X Change the block size to the required value.
Call the BlockSizeEditor.exe application in the easy Soft CoDeSys
directory of the programming software and select the block size.
Alternative option:
The following *.reg files are available in the installation directory
to enter the block size in the registry:
The download block size is defined in the following registry key:
The default block size is 20000
hex
(=128 Kbyte), the block size for
the routing is 1000
hex
(= 4 Kbyte).
Notes on routing
• If large files are written to the target PLC or read from the PLC,
it is possible that the online connection will be interrupted after
the transfer process has been completed. Renewed connection
is possible.
• If a program with a modified routing Node ID is loaded into the
target PLC via a routing PLC, the target PLC accepts the
modified routing Node ID; however, the communication
connection will be interrupted. Reconnection with a corrected
routing Node ID is possible.
• A controller cannot be connected via a routing connection if it
contains a program without any valid routing parameters (Baud
rate/Node ID).
• The routing does not depend on the configuration (master/
device): a target PLC that has not been configured as a master
or as a device can be accessed. It only has to be assigned the
basic parameters such as Node ID and baud rate, as well as a
simple program.
Addressing
Controllers on the CANopen bus can be configured a master or as
a device. The controllers are assigned a Node ID/node number
(address) so that they can be identified uniquely. The target
controller must also be assigned a (routing) Node ID if you wish to
access it by means of the routing function. The RS232 or Ethernet
interface can be used as a connection between the PC and XC200.
In the following diagram the routing controller is connected to the
PC via the RS232 interface.

You can change this setting only if you have administrator
rights on your PC (access to registry)!

have the same value as the Node ID (Device)!
