FP Web-Server V2.11

 

 

<?xml version="1.0" encoding="ISO8859-1"?>

<Production xmlns:xsi="http://www.w3.org/2001/XMLSchema-Instance"> <Unit>

<Type>{DT10_10_s}</Type> <Produced>{DT18_6_u}</Produced> <Rejected>{DT19_6_u}</Rejected> <State>{R11_off_on}</State>

</Unit>

</Production>

2.The XML file "Producn.xml" is transferred to the FP Web-Server unit via the FP Web-Configurator Tool. In this example we use an FP Web-Server unit with the IP address 199.199.26.52.

3.A TCP client can request the FP Web-Server unit's http server to deliver the XML file "Producn.xml" (including current PLC data), which takes on the form: http://199.199.26.52/plc?Producn.xml

This file can be read by an Internet browser or a user application program.

4.The client will receive the following resulting XML file, for example:

<?xml version="1.0" encoding="ISO8859-1"?>

<Production xmlns:xsi="http://www.w3.org/2001/XMLSchema-Instance"> <Unit>

<Type>Standard </Type> <Produced>332 </Produced> <Rejected>54 </Rejected> <State>off</State>

</Unit>

</Production>

In this example the following PLC data was currently available on the PLC:

String at DT10 = "Standard"

Integer value at DT18 = 332"

Integer value at DT19 = 54"

Internal relay R11 state = false

For programming examples in C++ and Java to read an XML file from the FP Web-Server refer to the online help under the keyword "Appendix K) Programming Samples: Access to the FP Web-Server / PLC via TCP".
