The Rack where the destination CPU is inserted. This value should be 0 in almost all cases. Only in Multi CPU configurations this needs to be adjusted.

The slot where the destination CPU is inserted in the selected Rack. This value depends on the particular hardware configuration of the CPU. Usually it is 2 for S7-300 CPUs and 3 for S7-400 CPUs On Redundant H-CPU configurations this value must be set accordingly, in order for the comunication to work properly

The MPI address of the remote CPU. this depends on the particular hardware configuration and is usually set to 2 by default. Only relevant for MPI connections

The IP-Adress or Hostname of the CPU's ethernet connection. Only relevant for ISO over TCP connections.

Defines the type of connection resource to use for communiction with the PLC Depending on the connection partner and connection type, the range of values is automatically limited to valid values or the value of the connection resource is assigned permanently.

Unknown connection resource

Programming device connection Free connection (not configured) At least one resource per CPU is reserved for programming device connections. However, for certain S7-300 CPUs it is possible to reserve multiple resources in the CPU properties. S7 connections that are typically set up from a programming device or from a PC (with ES functionality). This type of connection is used to configure and program the addressed station/module as well as to test and commission it; afterwards, the connection is typically cleared again. This connection resource allows both read and write access (e.g., monitoring and loading).

OP connection Free connection (not configured) At least one resource per CPU is reserved for OP connections. However, for certain S7-300 CPUs it is possible to reserve multiple resources in the CPU properties. S7 connections that are typically set up from an OP or from a PC (with OS functionality). This type of connection is used to monitor the addressed station/module with regard to the process that is being controlled.

Other Free connection (configured, unspecified connection) This connection resource can operate multiple connections. Use: Connection configured at one end with unspecified connection partner! The connection partner does not have to be configured if the connection resource 0x03 is addressed. Use is not specified. For example, this resource is used automatically when an S7 connection configured at both ends is configured from an S7-400 to an S7-300.

CPU Connections that are typically set up from a CPU to another module (CPU, FM, etc.) within a subnet. The connection setup is initiated by the application program, in which a connection configuration does not exist. This type of connection allows process data to be exchanged between the modules. For certain S7-300 CPUs, it is possible to reserve resources for S7 basic communication.

The block exists in the controller, and is also linked into execution. if this attribute is FALSE: -For Code blocks such as FB or FC, this means that they are existing in the controller but not actually executed -For data blocks this means, that they do not have any Actual values assigned to them. Any attempt to read current data from them will fail.

This corresponds to the "Unlinked" attribute in the Simatic manager, which actually shows the status in reverse This Attribute is only false when either especifically selected from simatic manager (only possible for Datablocks) or during a breif period when an Code block is alrady downloaded, but not yet linked (usually part of the "Block Download" process

This is an standard block from the default library

The block is protected by an Password

We could use that to simply load SDB0 from the plc and then parse the bytes directly

This is a Helper Function wich is used by GetSourceBlock

Returns the Parameter as an Int!

This Function Returns a byte Array of a Value Parameter

This Function Returns the Hex Value of a Parameter Pointer of a UC or CC.

These functions to Convert from MC7 to AWL could not be done withou the help of Steffen Krayer ! Many of the Code is from him (From his Delphi Prog) and also he created Excel sheets wich decribe how MC7 for most of the AWL Commands looks.

The general structure of an online block is as follows: 0 - 35 Block header 36 - x MC7 code for Code blocks; Current data for datablocks x - x Interface x - x Start Values (if any) x - x Segment table Len -36 Block footer. The footer is always located 36 bytes at the end of the block all values x are depending on the blocks layout and apropiate length fields must be parsed from code

This value marks the lenght of the actual Block header, and since the MC7 code immeadiatly follows, also marks the start of the MC7 Code or Datablock body

This value marks the lenght of the actual Block footer which is always situatted at the end of the MC7 code data

Parse the Header and Footer information from an online MC7Code byte blob

The online MC7 Code blob from the PLC The Mnemoric that should be used when parsing the Blocks data

This class is responsible for parsing Interface declarations from MC7. It parses all variables from the interface declaration and optionally fills in the startvalues and actual values. This class is used by the MC7 converter

The Interface of an MC7 block is structured as follows: Header: 0 Block Type: 0x05 (DB) 0x10 (DI) 1-2 Again Block Number or FB Number on a DI (but bytes swapped) 3-4 Interface Length minus this header (7 bytes) 5-6 Start Value Length Interface: 7-x Line 1 x-x Line 2 ... for more information about the format of an Interface Line, please look at GetVarTypeEN

Represents the Type of Parameter in an Interfacer, Not the Datatype. Basically ther are In, Out, INOUT, Static and Temp The _Init versions are the same with the above, except they have initial values that must ge parsed the _EX_ version are slightly different, in that they include an extra parameter in the interface declaration row. I think this parameter is some kind of BitFiled declaring some options, but i am not sure what it is? See GetVarEn function for details

Goes down in the parameter rows and finds the datarow corresponding to the In, Out or InOut parameter that corresponds to Index It goes throught the interface of the Function of FunctionBlock the same way as S7 would (first In, Out then InOut

The interface of the block The number of the Parameter of the block

Compares the structure of two Interface declarations and returns true if they are compatible and false if not They are compatible if the Structure and Datatypes match up. Datarow names are ignored, since the interface remain compatible as long as the general structure matches up. Also Actual values are ignores

The first interface to compare The second interface to campare

Parses the interface from an Step7 Source code as stored in Step7 Project Files

The Step7 Code to be parsed An list of Parameters that where found in the Step7 Declaration The block type that is beeing Parsed Indicates if an block is an Instance DB The BlocksOffline Folder where the parsed block code belongs to The Block where the Parsed Step7 code belongs to the current values of the DB, if it is an DB

Find and assign the Actual value of an Intervace to an given S7Datarow

OUT: an pointer for tracking the current value position in the parsing process

Parses the interface from an MC7 Interface block

The interface bytes from the MC7 code The corresponding Current data values. Only valid for DB OUT: The parsed Parameter list the block type of the block interface to be parsed Indicates if the data block belongs to an Function block The block header

Parses an Interface parameter Row from the Interface of an MC7 block

The Parent Interface Row of the rows to be parsed The Interface parameter data type"/> The parameter row is inside an struct the parameter row is inside an array The variable name to be used for the current row the interface bytes from the MC7 Code OUT: the current parsing position The current data bytes from the MC7 code OUT: the current parsing position for Initial values OUT: the parsed parameter row number OUT: The current parsing stack depth The prefix to be used to generate the variable names from The block, where the interface belongs to

Get corresponding current value. These values essentially have the exact same layout as one is familiar with the "GetBytes" interfaces From the communication library.

Get corresponding Initial value

The data-type of the interface row Either an Array containing the Start Values or Actual Values OUT: Current position of parsing the parsed value acording to the given datatyep and adress. If the datatype is invalid (such as struct) it returns Null The Initial values are encoded in an compacted manner. Meaning, if an varialbe does not have an Initial value, it does not appear in the start values list! this means the valpos must be tracked, and increased every time an Avlue was parsed from the array WARNING! be aware that for somehow reason Siemens encoded the Startvalues in Little Endien format, completly contrary to the comon S7 format! This means one can not use the Libnodave.Getxxx funcions, but rather has to use the usual Bitconverter Basically the logic here uses the default libnodave.getxxx function, but with Bitconverter instead.

Small helper class to keep track of the current Variable name

Returns the next Variable name and increments the internal Variable count

This Function Returens a Step7 Project Instance for every Project Folder in the Path.

Parses the AWL Text and returns the S7Blocks

Can be null

Sets the keep-alive interval for the socket.

The socket. Time between two keep alive "pings". Time between two keep alive "pings" when first one fails. If the keep alive infos were succefully modified.
