3.2.5 Statistics
To retrieve statistics using the command channel, execute the following command:
gSTAT
Statistics can also be retrieved using the URL:
http://<IP-address>/CmdChannel?gSTAT
The response is rgSTAT 0 followed by an XML formatted string. To read the response in an
web browser, change the view in the web browser to reflect the source code.
Note
The statistic response is only for the active reference object.
3.3 Control the sensor via Web API
The Web API supports using the command channel for reading and updating parts of the
device configuration.
The Web API also supports the functionality to do a backup of the device configuration to a
file and to restore the configuration again. This is a convenient way to handle configurations
without installing and using SOPAS Single Device.
3.3.1 Basic principles
The command channel has a set of basic principles:
• Only one command at a time can be executed.
• Inspector PIM60 responds to each command with a response that includes the result of
the command as well as error codes.
• A specific task to control the Inspector PIM60 includes the command together with its
parameters, see list of command types and parameters in Appendix B, “Command chan-
nel” (page 52).
• Writing a parameter can typically only be done when the device is in Edit mode. Reading
a parameter can be done in both Edit and Run mode.
• It is possible to block configuration changes by deselecting Allow changes via Web Server in
the Web Server tab in the dialog Interfaces and I/O Settings in InspectorPIM60 menu.
3.3.2 Command syntax
The Web API command channel has the following syntax:
http://<IP-address>/CmdChannel?<command>_<identifier>_<argument
1>_<ar-
gument
2>..._<argument
N>
The ACK message has the following syntax:
<ACK Command> <identifier> <errorCode> <returnValue1> <returnValue2> ...
<returnValueN> <errorMessage>
The command is sent as an ASCII string. The combination of a command with its parameters
will either change the device configuration or fetch information from the device. For more
