3 Advanced Buffer DF FA SE Correct usage of Siemens products Please observe the following: WARNING Siemens products may only be used for the applications indicated in the catalog and in the relevant technical description. If third-party products and components are used, these must be recommended or approved by Siemens. To ensure trouble-free and safe operation of the products, they must be appropriately transported, stored, assembled, installed, commissioned, operated and maintained. The permitted environmental and ambient conditions must be adhered to. Notices in the relevant documentation must be observed. CAUTION Changes to cabinet wiring! Changes to cabinet wiring may only be performed in zero-voltage state! An additional or modified wiring realized outside of the manufacturing enterprise requires an additional functional and insulation test. Electrostatic Sensitive Devices ESD Almost all SIMATIC modules are equipped with highly integrated components or elements in MOS technology. For technological reasons, these electronic components are very sensitive to overvoltage and, consequently, to electrostatic discharge: The short designation for such electrostatic sensitive components/modules is: "ESD", which is the commonly used international abbreviation of ESD (Electrostatic Sensitive Device). NOTICE Electrostatic Sensitive Devices ESD! The presence of this symbol on cabinet, rack or packaging labels indicates the use of electrostatically sensitive devices and thus the touch sensitivity of these components. These modules can be destroyed by voltage and energy far below the limits of human perception. Voltages of this kind occur as soon as a device or an assembly is touched by a person who is not electrostatically discharged.

1. Advanced buffer Ext_Buffer_CP_4 1.1. General In case of a failure of communication on the IEC telecontrol connection, the frames will be written in the RAM memory of the CPU firstly.

6 1. Advanced buffer Ext_Buffer_CP_ General In case of a failure of communication on the IEC telecontrol connection, the frames will be written in the RAM memory of the CPU firstly. If all available RAM is used the frames will be routed to the memory of CP443-1 Advanced. If the connection is available again, first the oldest information is transmitted until the buffers are empty. After startup (restart of CPU / activation of Do_Restart (FB100)/ Clr_Ini_Buf (FB181)) messages will be buffered only, if the connection to a control center was established minimum one time. The monitoring of communication loss begins 20 seconds after startup. General interrogation commands will be delayed as long as buffer operations (read/write) are active. So, interrogated information need not to be routed through the buffers additionally. For a failure-free use, a CP443-1 Advanced with the MLFB 6GK7443-1GX20-0XE0, FW V2.0 or higher is necessary. CALL "Ext_Buffer_CP_4", DB181 Comp_ID := P_Application :=#P_Appl ID_FTP_1 :=2 Laddr_FTP_1 :=W#16#64 ID_FTP_2 := Laddr_FTP_2 := Max_No_Infos :=L#50000 Min_Free_CPU_Mem :=L# Clr_Init_Buf :=M9.0 No_of_Infos_in_Buffer:=MD10 Buf_OV :=M9.1 Startup :=M9.2 FB_RetVal_1 :=MW20 FB_RetVal_2 :=MW22 RAM_Size :=MD24 View as CFC-block with default values View in AWL with partial parameter supply Important features are: With a small effort of parameterization the advanced send buffer can be created. This buffer is controlled in RAM memory of CPU and in the memory of the CP443-1 Advanced. The buffer can be managed redundant (in 2 separated CPs). On the one hand default settings can be read in the corresponding variable commentary on the other hand they need only a minimum of necessary inputs. At least the wiring of P_Application, ID_FTP and Laddr_FTP of one connection is necessary. The information objects, sorted after their priority, are stored in the memory of the CPU / CP. the objects in CP memory can be watched with a web browser or FTP client tool. From version V1.6 it can be fixed by parameter at which RAM status the transfer to the CPs should start. From version V1.6 the block can be also used without CP. The buffering is exclusively carried out in the CPU RAM (at under-usage of the parameterized limit as well). The block may be only used in S7-400 systems and is available for SIMATIC-Manager not for TIA. SIPLUS RIC IEC on S7 V1.6 Page 6 of 13 SIEMENS AG 2015

Assign different numbers inside a block type as byte-variable. For example B#16#1. Pointer which has to be connected to the output 'P_Application' on block 'S7_IEC_Config' (FB100). It refers to all data required internally, such as send and receive buffer, etc. ID_FTP_1 / _2 That is the ID from the connection configuration (NETPRO) e.g. 1. The value can be taken from NETPRO / settings TCP-connection / Block parameters. Not used FTP-Connections shall be switched off with the value 0. Laddr_FTP_1 / _2 Max_No_Infos Min_Free_CPU_Mem from V1.6 Clr_Init_Buf No_of_infos_in_Buffer Buf_OV Startup from V1.6 This is the hardware-address of the CP-module with which the FTP-connection is built. It can be taken from the hardware configuration or from NETPRO / settings TCP-connection / Block parameter. Maximum number of buffered elements in the CP-memory With under-usage of the RAM limit parameterized here the block starts transferring data to the CP. The parameterized lower limit may be exceeded temporary. If no FTP connections are projected this parameter is ineffective. A rising edge causes all information in the buffers to be cleared. Additionally an initialization of the buffers is done. Number of elements that are in the CP-buffer at the moment. Indicates a buffer overflow information are lost The block starts buffering only after the communication connection was already established and disrupted afterwards. It doesn t buffer if the communication is disrupted already from startup. The output signals with True that the buffer block has still not recognized an operating communication and is thus NOT buffering. This status can occur as well after faults which initialize the block internally. Such a fault is indicated in each case at the FB_RetVal but not mandatory permanent.

9 Hints Redundancy mode (both connections are active) In case of a detected connection error all information are stored in RAM memory of CPU first and then in both CPs (assigned via ID and Laddr). They are read normally from the first assigned CP. Only if there is an error, the second CP will be used. Error 820x will be set, if the communication is or was faulty and stored data (in this CP) may be incomplete. The error code will be reset, when No_of_Infos_in_Buffer reaches 0. Buffering the information in RAM memory of CPU Before buffering into file system of CP/s, FB181 uses first the available RAM memory of CPU (adjustable from V1.6, see parameter Min_Free_CPU_Mem ). This increases performance of the system. The currently available memory is monitored on a new output 'RAM_Size' of FB181. Because of creating lots of DBs at runtime, please observe that 'First_internal_DB_No' (FB100) points to a not used, but available, area of DB numbers. Running on hardware CPU417H more than Information can be stored in RAM, therefore it isn't necessary to use the CP-buffering in case of connection failure to control center. Running on hardware CPU412H please check first, that there is enough memory for startup (if you are not sure please check FB_RetVal of FB181 after start up). For successful startup FB181 needs at least 20 kbytes. All additional free memory (especially the first 16/32/48kB) helps to get faster in case of buffering. No buffering after startup of CPU After startup of CPU (restart of CPU / activation of 'Do_Restart' (FB100) / 'Clr_Ini_Buf' (FB181)) information will be buffered only, if the connection to control center was established and fails again. The detection of communication loss starts 20 seconds after start up. Delay of general interrogation General interrogation commands will be delayed as long as a buffer operation is active (read/write). Therefore no longer all GI-information have to be routed through the buffer. Please note the permissible value ranges of the block parameters. They are not mandatorily checked for plausibility. Incorrect inputs can trigger unpredictable responses and incorrect functions. Siemens Parts SIPLUS RIC IEC on S7 V1.6 Page 9 of 13 SIEMENS AG 2015

11 In the register Users at least one user has to be defined: everybody with the right access files on the S7 station with FTP Settings in NETPRO To use the buffer function, you have to build one or two (in redundancy mode) FTP-connections to the CP443-1 Advanced. Please go on as follows: Select the CPU (e.g. CPU 412-3H) Choose in menu Input New connection Choose the connection type TCP-connection and for connection partner not specified In the now opening window Properties TCP-Connection please select the checkbox Use FTP Protocol Please note at this point the parameters ID and LADDR at block parameters. These parameters are necessary for calling FB181. Siemens Parts SIPLUS RIC IEC on S7 V1.6 Page 11 of 13 SIEMENS AG 2015

Further settings are not necessary. Save & translate your configuration and finally load it to the CPU. Notes: The CP443-1 Advanced with Firmware 2.

12 Further settings are not necessary. Save & translate your configuration and finally load it to the CPU. Notes: The CP443-1 Advanced with Firmware 2.0 works incorrect, if the CPU was reset -> Error 81FF. At the Moment (state 07/2010) the problem can only be solved, if the CP-module is pulled out/ plugged in or the whole rack is switched off and on again. A solution to this problem is in work. The information is stored in files in the CP. The file system can be watched with a web browser or a FTP- Client (e.g. FTP-commander ). Up to max information are stored per file. If more than the parameterized number (FB181: Max_No_Infos) information are stored, the oldest file with the lowest priority is deleted. The filenames are IEConS7_xx_yy_zzz.job (xx: connection-id (Netpro), yy: Prio, zzz: continuous file number). SIPLUS RIC IEC on S7 V1.6 Page 12 of 13 SIEMENS AG 2015

13 1.3. Embedding of FB181 in a STEP7-Program For a correct function the FB181 Ext_Buffer _CP_4 should be called following FB100 and FB121-call ( S7_IEC_Config and SL_Org_Asdu_1 ) in OB1. Polling parameter of FB181 Name the polling parameters as described above: CALL "Ext_Buffer_CP_4", DB181 Comp_ID :=B#16#1 P_Application :=#P_Appl_1 ID_FTP_1 :=10 Laddr_FTP_1 :=W#16#FA0 ID_FTP_2 :=10 Laddr_FTP_2 :=W#16#FA1 Max_No_Infos :=L#10000 Clr_Init_Buf := No_of_Infos_in_Buffer:= Buf_OV := FB_RetVal_1 := FB_RetVal_2 := RAM_Size := The input parameter P_Application is the output parameter of the before happened call of FB100 S7_IEC_Config. You can get each, ID_FTP and Laddr_FTP, from the connection configuration in NETPRO. Note: Instead of instance block DB181 you can choose a free, user-defined DB.
