Introduction

Overview

Initial situation The common File Transfer Protocol (FTP) offers you the opportunity to store data on server systems. FTP supports almost all server and operator systems. All controllers of the product families S7-300, S7-400 and S7-1500 support the FTP communication via special communication processors (CPs). This application example shows you how a S7-1200 or S7-1500 can also use the FTP communication without a special CP with certain FTP servers on the basis of the open user communication (TCON, TSEND, TRCV and TDISCON).

Note

The function of this application example can only be guaranteed with the FTP servers tested.

1 Introduction Description In many projects and on many systems it is necessary to exchange process data between controllers and servers/PCs, so that it can also be worked with the incoming data outside of the control level. This is made possible by standardized protocols. FTP is a simple protocol which works according to the client-server principle and fulfills this task. So far, users who used a S7-300, S7-400 or S7-1500 could only exchange process data with a CP via FTP using a FTP server. In this application example, S7-1200 and S7-1500 are integrated into the existing FTP environment without communication processor. Advantages The solution presented here offers the following advantages: Simple and easy to understand FTP communication with an S7-1200 or S71500 via the "Ftp1X00Cmd" block.



The command set of the block corresponds to that of the FTP communication via S7-300, S7-400 or S7-1500 controllers with CP.

The FTP function block delivered with this application example exclusively fulfills FTP client functions.

Restrictions


The following restrictions apply for this application example.

Note



The application example works only with the tested FTP servers and as of the software version tested.



Only four FTP users can be connected at the same time from a controller to a FTP server.



FTPS functionality cannot be integrated.



With a S7-1500 a maximum of 65536 bytes can be sent and with a S7-1200 a maximum of 8192 bytes can be sent.



For non-optimized access the lower or upper limits of arrays are at -32768 or 32767.



For optimized access the lower or upper limits of arrays are at -2,147,483,648 or 2,147,483,647.



For S7-1200 and S7-1500 the maximum size of data to be received depends on the maximum size of the reception memory of the CPU.

This note applies to S7-1500-CPUs For a block with the "Optimized block access" property, an element of the Bool data type requires a storage area of 1 byte. The same is the case for arrays of Bool:

2 Engineering

Interconnecting fixed parameters of the "Ftp1X00Cmd" block Before you are using the "Ftp1X00Cmd" block for the FTP communication, the following parameters have to be interconnected: 

"connectionID"



"username",



"password",



"filename",



"ftpData"



"connectionData"

Interconnect the parameters as described in the interface description chapter. In order to control the block you also have to interconnect the inputs "connect", "execute", "ftpCmd" and "ftpActiveMode". In the application example, these inputs are interconnected with "PLC tags". The tags used are listed in the tag table included. The following figure shows the call of the "Ftp1X00Cmd" block in the application example.


Figure 2-3

Note

The interconnection of the parameters described here is the basic requirement for the operation of the block. Without an interconnection, a controller connection to the FTP server cannot be established. The specified user has to be created on the server side in order to be able to establish the connection.

2 Engineering

Data transfer of user-defined structures With the "Ftp1X00Cmd" block, you cannot only send or receive an array of bytes or characters but also specific data types or independent structures (data type "STRUCT"). To do this, some adjustments have to be made on the SCL code of "Ftp1X00Cmd". The following table explains what you have to change on the SCL code. Table 2-5


No.

Note

Action

Description

1.

Interconnect the "DATA" INOUT parameter of the "InstTrcvDataConn" multi instance in code row 737 with the "ftpData" INOUT parameter of the "Ftp1X00Cmd" block.

The data received on the data connection is now no longer saved in a data buffer but is directly transferred to the "ftpData" INOUT parameter.

2.

Comment out the code rows 405 to 420.

Since the data is directly transferred to “ftpData”, the data buffer no longer has to be copied.

3.

Interconnect the "ftpData" INOUT parameter of the "Ftp1X00Cmd" block with the structure used by you.

The structure attached by you is now used for sending ("STORE"/"APPEND" command) and receiving ("RETRIEVE" command).

If you adjust the code, a maximum of 8192 bytes can be received by "Ftp1X00Cmd".

2.4 Note

Operating "Ftp1X00Cmd" The prerequisite for successful operation is that the FTP server is compatible with the "Ftp1X00Cmd" block and that it has been configured as described in chapter 2.2.

Description of the operation of the "Ftp1X00Cmd" block The "Ftp1X00Cmd" block is mainly controlled via the inputs "connect", "execute", "ftpCmd" and "ftpActiveMode". This is where the "connect" input, controls the connection establishment and termination of the controller connection to the FTP server. As long as data is exchanged it has to remain "connect" TRUE. If "connect" is set to FALSE the termination of the controller connection starts and the user connected to the FTP server is logged out. The FTP command for data transmission (2=STORE, 3=RETRIEVE, 4=DELETE, 6=APPEND) is specified using the "ftpCmd" input. The transfer mode (TRUE=active, FALSE=passive) is specified using the "ftpActiveMode" mode.


As soon as the controller has a controller connection to the FTP server (output "connected"=TRUE), a FTP mode is set, a valid FTP command has been selected and a valid file name/path specified, you can process FTP commands with a positive edge on the "execute" input. The following figure is to illustrate the dependencies of the inputs and outputs of the "Ftp1X00Cmd" block. Figure 2-4 username

Valuable Information

3.1

Basics

FTP general FTP was developed to exchange data between a client and a server. Furthermore, it is designed for managing directories via remote access. In the world of automation technology, FTP is a useful protocol to easily exchange data. There are two modes for FTP communication: 

active FTP



passive FTP

FTP active


In this mode, the FTP client opens a random port (>1023) and sends it and its own IP address to the FTP server using a special command (PORT or EPRT). By default, the command is sent to port 21 of the FTP server. Port 21 of the server has to be open or forwarded in the firewall of the server; otherwise no communication will be established. When data transfer is requested, the FTP server initiates a data connection to the transferred IP address and FTP server port 20. The active mode is used when the FTP server is located behind a firewall, since the data connection is initiated from the FTP server outwards and is therefore not blocked by the firewall. Hence, the FTP server reacts actively. The figure below illustrates the active FTP communication on the example of the RETRIEVE command. Figure 3-1

3 Valuable Information FTP passive In this mode, the FTP client sends a PASV or EPASV command to port 21 of the FTP server. The FTP server then opens a random port and transmits this port number to the FTP client together with its IP address. For the data transfer, the FTP client now initiates a TCP connection to the IP address sent by the FTP server and the port. If the FTP client is located behind a firewall, the passive mode is used. The stateful packet inspection normally always allows outgoing data packets in the firewall. Hence, the FTP server reacts passively. The figure below illustrates the passive FTP communication on the example of the RETRIEVE command: Figure 3-2
