7 Automation Problem 1.1 Overview Automation Problem Overview Introduction The exchange of small data volumes between an S7-300 station and the WinAC MP software PLC via Industrial Ethernet is realized with little configuration and programming overhead. Overview of the automation problem The figure below provides an overview of the automation problem. Figure 1-1 S7 station A (server) Transfer of small data volumes based on S7 communication S7 station B (client) Industrial Ethernet Description of and requirements for the automation problem Based on S7 communication, this application is to be able to exchange small data volumes between two S7 stations via an interface that is easy to parameterize and control. Data exchange via Industrial Ethernet is initiated cyclically or process-controlled from the client. One of the two S7 stations (S7 station B) acts as a client. The client actively establishes the communication connection to transfer the data. The second S7 station (S7 station A) acts as a server. The server is passively involved in establishing the connection. The configuration of the communication connections and the call of necessary communication function blocks or system function blocks are performed only in the client. This ensures that there is little configuration and programming overhead for the user. V1.0, ID Number:

8 Automation Solution 2.1 Overall solution overview Automation Solution Overall solution overview Diagrammatic representation The following figure schematically shows the most important components of the solution: Figure 2-2 Server S7-300 with CP343-1 S7 communication Client MP Touch -PUT / GET - WinCC flexible Runtime IP address: Passive connection establishment Industrial Ethernet IP address: Active connection establishment Configuration The small data volumes with max. 160 bytes are transferred between two S7 stations, for example using an S7-300 station with Industrial Ethernet CP and MP377 Multi Panel. In this application, the following hardware components are connected to each other using Industrial Ethernet cables: MP Touch Multi Panel with installed WinAC MP 377 software PLC S7-300 station with CP343-1 The MP Touch Multi Panel is located in the same IP subnet as the S7-300 station with CP The FB4 GET_PUT function block is called in the user program of the WinAC MP software PLC. This function block encapsulates the SFB14 GET and SFB15 PUT system function block calls for the data transfer and provides the user with a simple interface. Thus, S7 communication with the PUT and GET services is used for the data exchange between the WinAC MP software PLC and the S7-300 station. The WinAC MP software PLC acts as a client for the S7 communication. The connection configuration and the realization of the PUT and GET services are performed in the client that actively establishes the communication connection. The S7-300 station acts as a server for the S7 communication, i.e. it is passively involved in establishing the connection. In the S7-300 station, a connection configuration and a call of communication function blocks or system function blocks are not necessary to realize write and read services. In addition, the send and receive data of the Win AC MP software PLC is visualized in WinCC flexible Runtime on the MP377 Multi Panel. 8 V1.0, ID Number:

10 Automation Solution 2.2 Description of the core functionality 2.2 Description of the core functionality Overview and description of the user interface Figure 2-3 The send and receive data of the WinAC MP software PLC is visualized in WinCC flexible Runtime. The send data that is written from WinAC MP to the S7-300 station via Industrial Ethernet is stored in the DB100 data block. The receive data that is read from the S7-300 station by WinAC MP via Industrial Ethernet is stored in the DB200 data block. The unidirectional write and read services are controlled in WinCC flexible Runtime using the following switches and buttons: M10.0 and M11.0 to enable the unidirectional write and read services M10.1 and M11.1 for cyclic data transfer M20.1 and M20.2 for single data transfer Sequence of the core functionality Table 2-1 No. Action Note 1. Set the M10.0 and M11.0 switches to enable to enable the unidirectional write and read services. 2. Set the M10.1 and M11.1 switches to enable to cyclically write the data to the S7-300 or read the data from the S7-300 station. When the switches are in the enable position, they are displayed in green. When the switches are in the enable position, they are displayed in green. 10 V1.0, ID Number:

11 Automation Solution 2.2 Description of the core functionality No. Action Note 3. Click on the M20.1 or M20.2 button to write the data once to the S7-300 station or to read the data once from the S The M20.1 and M20.2 buttons can be used only when the M10.1 and M11.1 switches are in the disable position. When the switches are in the disable position, they are displayed in red. Advantages of this solution Multi Panels have an operating system that is designed for embedded, does not require much main memory and meets real-time and deterministic requirements. Their rugged construction and compact design makes Multi Panels suitable for use in harsh industrial environments. WinAC MP is the economical solution for small and medium-sized applications and automation problems. Concerning communication, there is only little configuration and programming overhead for the user, since: the S7 connection has to be configured only in the WinAC MP software PLC. the communication functions for the unidirectional write and read services are called only in the user program of the WinAC MP software PLC. the FB4 GET_PUT function block encapsulates all system function block calls for executing the unidirectional write and read services and thus provides an interface that is easy to paramaterize and control. Since there is little configuration and programming overhead with regard to communication, the user saves time and costs. Advantages of S7 communication The Internet service portal of Siemens AG, Industry Automation and Drive Technologies, provides information on the properties, advantages and characteristic features of the S7 protocol (see \11\).

The configuration of the S7 connection and the call of the SFB14 GET and SFB15 PUT system function blocks for reading and writing the data are performed in the WinAC MP software PLC. The software PLC actively establishes the S7 connection. The S7-300 station is passively involved in establishing the connection. Only data blocks in which the send and receive data is stored are required in the S7-300 station. Program overview Figure 4-5 S7-300 station Send data DB100 Receive data DB200 Read data (32 words) S7 connection Write data (32 words) WinAC MP software PLC OB1 DB4 Receive data FB4 SFB14 GET DB200 SFB15 PUT Send data DB V1.0, ID Number:

17 Functional Mechanisms of this Application 3.1 S7 communication basics FB4 GET_PUT is called in the user program of the WinAC MP software PLC. Internally, this function block calls the SFB14 GET and SFB15 PUT system function blocks. The data is then read from the S7-300 station or written to the S7-300 station. The data transfer with FB4 GET_PUT is performed word by word. The maximum number of data to be read or written is 80 words (=160 bytes). In this application example, 32 words are read cyclically from DB100 of the S7-300 station. The start address is word 0 in DB100. The read data is stored in DB200 of WinAC MP. The start address is word 0 in DB200. In this application example, 32 words are cyclically written to DB200 of the S7-300 station. The start address is word 0 in DB200. The data that is written to the S7-300 is stored in DB100 of WinAC MP. The start address is word 0 in DB100. User program of the WinAC MP software PLC The user program of the WinAC MP software PLC consists of the following blocks: Table 4-8 Block Symbolic name Description OB1 CYCL_EXC The FB4 GET_PUT function block including the DB4 instance data block is called cyclically in OB1. FB4 GET_PUT Internally, FB4 calls the SFB14 GET and SFB15 PUT system function blocks. Thus, the unidirectional PUT and GET write and read services for exchanging small data volumes are implemented together in one function block. DB4 idb_get_put The static variables of FB4 are stored in the DB4 instance data block. SFB14 GET Using the SFB14 GET system function block, the WinAC MP software PLC reads out the data from DB100 of the S The read data is stored in DB200 of WinAC MP.
