Content	288Functional Example No. AS-FE-I-009-V10-EN Ex. No.9Sample Code Preliminary Remarks Enclosed, we offer you the STEP 7 project as sample code with which you can reset the functionality described here. The sample code is always assigned to the components used in the functional examples and implements the required func- tionality. Problems not dealt with in this document are to be implemented by the user; the sample code may serve as a ba- sis. Password In all cases, the passwords used for the safety-relevant part is „siemens“. Use of the STEP7 Project Two three-phase asynchronous motors can be started inde- pendently of one another with separate push buttons (NO). The motors are either safely stopped: 1. individually (respectively one emergency stop button as- signed to one group) or 2. as group shutdown. An emergency stop button exists that switches off all groups (stopping all motors). Download The download is available via the following link: http://support.automation.siemens.com/WW/view/en/ 21330890 To call the corresponding project file, open the as_fe_i_009_v10_code_singlegroup.zip file offered as a sep- arate download (on the HTML page) and extract it into a user defined directory. For downloading the project into the F-CPU please proceed as follows: ■First load the hardware configuration into the S7-CPU ■Switch to the SIMATIC Manager ■Select the Blocks container ■Menu Options -> Edit safety program ■Click the Download button The sample code with the given configurations enables the following: ■Independent starting of two motors M1 (group 1)and M2 (group 2). ■Safe shutdown of individual groups (motor M1 and/or M2) ■Group shutdown for both motors (M1 and M2) Note Operational stopping has not been prepared in this example. Program procedure The standard user program consists of two networks of OB 1. Network 1 The signal for operational starting (START_M1) for group 1 consisting of motor M1 is given in network 1. The INSTANZ_FB1 . ensures that the motor cannot be started with an acknowledgement transmitted in the safety program. As long as on of these bits is 0 , COND1= 0 re- mains true also if the start button is pressed, since the reset function has priority in this flip-flop type. Network 2 Basically the above information on network 1 applies to group 2 with motor M2. The information of the flags COND1 and COND2 from the networks 1 and 2 is read in the safety program as flag COND1_F or COND2_F. This allocation occurs in the cyclic in- terrupt OB 35 for the following reason: If you want to read data from the standard user program (flags or PII of standard I/O) in the safety program (here: COND1 or # GH .
