Post Configuration
Post Configuration Presentation
Introduction
Post configuration is an option that allows you to modify some parameters of the application without changing the application. Post configuration parameters are defined in a file called
Machine.cfg, which is stored in the controller.
By default, all parameters are set in the application.The parameters defined in the Post
Configuration file are used instead of the corresponding parameters defined in the application. Not all parameters have to be specified in the Post Configuration file (for example: one parameter can change the IP address without changing the Gateway Address). All parameters in the Post
Configuration file without corresponding hardware are ignored (for example, a PCI module configuration without a PCI module).
Parameters
The Post Configuration file allows you to change network parameters.
Ethernet parameters:
IP Address
Subnet Mask
Gateway Address
Transfer Rate
IP Config Mode
Device Name
Serial Line parameters, for each serial line in the application (embedded port or PCI module):
Baud rate
Parity
Data bits
Stop bit
Profibus parameters, for each Profibus in the application (PCI module):
Station address
Baud rate
NOTE: Parameter updates with a Post Configuration file that impacts parameters used by other devices via a communication port are not updated in the other devices.
For example, if the IP address used by an HMI is updated in the configuration with a Post
Configuration file, the HMI uses the previous address. You must update the address used by the
HMI independently.
