4 1 Application description Preposition Aim of the application This application has been created in order to provide users with a possibility of quickly and simply connecting a MICROMASTER 4 or a SINAMICS G120/G120D drive converter with Control Units CU240S/D DP/DP-F or CU230P-2 to a SIMATIC S7-300/400 control system via PROFIBUS DP. To do this, a STEP7 project example has been created in which the FC14 function block is used to establish communications between the MICROMASTER 4 and a SIMATIC S7-300/400 control system via PROFIBUS DP. This application shows the possibilities that users have when using the FC14 function block and which parameters and interface signals can be exchanged between the FC14 function block and the user program (AWP). This application also shows how the STEP7 project example should be used. Scope The following main points are discussed in this application: Description of the FC14 function block Use of the STEP7 project example Exclusion This application does not include a description of the SIMATIC STEP 7 programming tool the basic commissioning of the frequency inverter It is assumed that readers have fundamental knowledge about these particular subjects. Validity The example applies to an implementation with STEP 7 V5.x for all PROFIBUScapable... MICROMASTER 4 SINAMICS G120 / G120C / G120D If you work with a SIMATIC S or S in the TIA Portal, you better use FB SINA_SPEED (FB285) from "DriveLib_S71200/ ". Function block, description and instructions how to configure and to include you will find under Entry-ID: , V3.2, 01/2014 4

5 1 Application description 1 Application description Here, you will obtain an overview of the functions of the FC14 function block, parameter settings of the drive and information on how to use the STEP7 project example. Overview Using the FC14 function block it is now possible to quickly and simply couple a MICROMASTER 4 or a SINAMICS G120/G120D drive converter with Control Units CU240S/D DP/DP-F or CU230P-2 to a SIMATIC S7-300/400 control via PROFIBUS DP. The block provides the user with a simple control and setpoint interface. The signals used are comparable with the control and setpoint interface via terminal strip. The following parameters and interface signals are exchanged between the FC14 and the user program. Table 1-1 Default assignment of interface FC14 Name Type Default Designation AWP FC14 hw_config_i_o_address INT 256 drive_on_off BOOL M = ON 0 = OFF1 drive_reversing BOOL M 0.1 drive_fault_ackn BOOL M 0.2 Peripheral input and output address according to HW-Config, e.g = setpoint inversion 0 = no setpoint inversion 1 = acknowledge fault 0 = no significance drive_f_setpoint REAL MD 2 Frequency setpoint between Hz FC14 AWP drive_in_operation BOOL M = operation enabled 0 = operation inhibited drive_fault_active BOOL M = fault 0 = no fault drive_alarm_active BOOL M = alarm 0 = no alarm drive_f_act REAL MD 6 Frequency actual value in Hz Function block FC14 is integrated in a functioning and tested STEP 7 project example ( FC14_PROFIBUS_DP_en ). The user can use the project unchanged, or for different hardware platforms can use the block container from the project example. The FC14 is not write-protected and when required, can be adapted. Internally, using direct I/O access operations, two words can be exchanged between the control and the drive. Control word 1 and the main setpoint are transferred from the control to the drive. The drive sends status word 1 and the actual output frequency back to the control. Entry-ID: , V3.2, 01/2014 5

If required, adapt the slave address! P0922 * Selection of PROFIdrive Standard Telegram 1 1 = Standard Telegram 1 NOTE The PROFIBUS slave address can either be set using the DIP switch at the PROFIBUS module or using parameter P0918. The DIP switch setting has priority and is displayed using parameter P0918 if the DIP switch is not = 0. This means that the address defined in parameter P0918 is only valid if the DIP switch = 0. * Set only for SINAMICS G120/G120D Entry-ID: , V3.2, 01/2014 6

8 3 Additional information 3.2 2nd step hardware configuration 3.2 2nd step hardware configuration If you use the hardware configuration in the project example, compare all of the components, issues and PROFIBUS addresses with your actual configuration. If required, adapt the configuration. Figure 3-2 Hardware configuration Download the hardware project into the S7-CPU. The hardware project must run, error-free! Entry-ID: , V3.2, 01/2014 8

9 3 Additional information 3.3 3rd step STEP 7 program 3.3 3rd step STEP 7 program FC14 is cyclically called in OB1. The FC14 interface is pre-assigned the appropriate default values as listed in Table 1-1. When the hardware configuration is changed or another FC14 interface parameter is used, then the block call must be appropriately adapted in the OB1. Set the operating mode switch on the CPU to RUN. The program must be executed error-free. NOTE FC14 uses UDT11 and UDT33 and they may neither be deleted nor re-named. The user-defined data types (UDT) have been generated for control word 1 UDT11 and status word 1 UDT th step operation The function block can be simply operated using the VAT1 table of variables.

10 4 Entering the reference frequency 4 Entering the reference frequency If it is necessary to operate motors at frequencies greater than 50 Hz (e.g. 87 Hz or 100 Hz, up to a max. of 650 Hz) on a frequency inverter, in the project example "FC14_DP_Ref_Freq_en" it is possible to additionally enter a reference frequency for the inverter. This reference frequency is used to convert the setpoint and actual value in the CPU. This reference frequency must correspond to the reference frequency P2000 in the frequency inverter in order that the setpoint and actual value are precisely calculated. NOTE The user must set the maximum frequency P1082 and the reference frequency P2000 in the frequency inverter. Example: Entering the reference frequency Frequency setpoint Actual frequency Figure 4-1 Entering the reference frequency Entry-ID: , V3.2, 01/
