9 Commissioning 3 Commissioning 3.1 Concept of the oscilloscope function The oscilloscope function includes two matching subfunctions. Measuring with function block OSZ - Data detection - Triggering for certain events - Data storage in a scalable ring memory For these measurements, the controller provides the function block (FB) OSZ. It is connected like any other FB (see 9300 Manual, software version 2.x). For configuration see chapter 4.2. Operation and visualisation with GDC using a PC - Setting of the measuring functions - Reading and display of the measuring values - Processing of the measurements (loading, storing, printing, etc.) The visualisation is part of the PC program Global Drive Control (GDC). GDC offers additional functions to analyse the measuring values. LECOM-xx or system bus (CAN) transfer data between controller (measuring with FB OSZ) and PC (operation visualisation). Oscilloscope function Measuring with FB OSZ in the controller Operation, visualisation with GDC using a PC Data detection - Triggering -Datastorage Data transfer Setting of measuring function Display of measuring values Processing of measurements FIG 3-1 Structure of the oscilloscope function OSZBA

19 Configuration 4 Configuration 4.1 Configuration with Global Drive Control The FB configuration must be set via the code to ensure that the FB records the signals appropriately. With the PC program Global Drive Control (GDC) Lenze offers - an easy to understand, - well structured, - convenient tool for the configuration of your specific measuring task. Function block library - GDC provides an easy-to-read library of available function blocks (FB). - GDC also displays the complete assignment of a FB. Signal configuration The signal is configured via one dialog box only. It is possible: - to display every FB as a block diagram. - to see all connections of inputs and outputs at a glance. - to link inputs. - to enter the FB in the processing table. - print your signal configuration as list. Note! - GDC is not part of the packing list. - The version GDC V3.2 offers an even more convenient FB editor. This editor makes the signal configuration easier by, for instance, graphical connection of function blocks. - Order information can be obtained from the chapter Accessories in Planning. OSZBA

21 Configuration Description of the codes Function Code Selection Description OSZ mode Controls the measurement in the controller C Starts recording the measuring values 0 - Cancelling of a measurement OSZ status Displays five different operating states C Measurement completed - The measuring value memory is completely filled with measuring data. The measuring values can be retrieved via PC. 2 - Measurement active - A measurement has been started with C0730 = 1. The FB waits for a valid trigger event. 3 - Trigger detected - The FB has detected a valid trigger event. According to the trigger delay, filing of measuring data is not completed yet and ends automatically when the last memory location is filled. 4 - Mesuring cancelled - Cancellation of a measuring value record (C0730 = 0). The measuring value memory is filled with the last measured data. The data can be retrieved via PC. 5 - Read data memory - The measuring data memory is being read. Settings are not possible yet. Configuration OSZ channel C0732/1 to C0732/4 - Connects the measuring channels of the FB to the signals of the process environment. - Any analog signals can be assigned to the four measuring channels. Entry of the corresponding signal number in C0732/1... C0732/4. - Connect channel 1 first, then channel 2, and so on. Unused channels are automatically assigned to signal FIXED 0%. Configuration OSZ trigger Trigger source Trigger signal C0733/1 Connects the digital trigger input to a digital signal of the process environment. - Any digital signal can be assigned to the trigger input. Input of the corresponding signal number in C0733/1. Determines the trigger source C Source is one of the four measuring channels (C0734/1... C0734/4) 0 Source is the digital trigger input (C0733/1) Determines the signal, which activates triggering - Triggering in an analog input channel - With a LOW-HIGH trigger signal, the analog trigger signal must exceed a defined trigger level to activate triggering. - With a HIGH-LOW trigger signal, the analog trigger signal must fall below a defined trigger level to activate triggering. - Triggering in a digital trigger input - With a LOW-HIGH trigger signal, the signal must change from LOW to HIGH to activate triggering. - With a HIGH-LOW trigger signal, the digital trigger signal must change from HIGH to LOW to activate triggering. FIG 4-2 displays the triggering of an analog signal with positive signal. C HIGH-LOW trigger signal 0 LOW-HIGH trigger signal Trigger level C Determines the trigger level which activates triggering when being exceeded. - The trigger level is only monitored, if one of the four channels is triggered. - With digital triggering, the trigger level is not effective.

22 Configuration Function Trigger delay Code Selection Description The trigger delay determines when the measuring values are filed with reference to the trigger instant. C %... 0 % - Negative trigger delay (pre-triggering) - Defines part of the memory. This part of the memory contents is filled with measuring values before triggering (see FIG 4-3). 0 % % - Positive trigger delay (post-triggering) - Defines part of the memory. The filing of the measuring values after triggering is delayed by this part of the memory contents (FIG 4-2). Memory contents Trigger level Trigger instant Signal measured Signal flow before triggering Signal flow after triggering FIG 4-2 Example: Trigger level and trigger delay with approx.-30 % post-triggering Memory contents Trigger instant Trigger level Signal measured Trigger delay Signal flow before triggering Signal flow after triggering FIG 4-3 Example: Trigger level and trigger delay with approx. -30 % pre-triggering 4-4 OSZBA0299

23 Configuration Function Code Selection Description Scanning period Number of channels C ms min - Setting of the scanning period - The scanning period is the time between two measurements. - The measurements are carried out for all channels at the same time (e.g. a value is measured at channel 1 simultaneous to a measurement in channel 2, 3or4). - The scanning period can be adjusted to one, two, or five steps. C0739 Number of channels, which are used for measuring. Read data The code is required when not using GDC for the visualisation. memory C0740/ Determines the start of reading the data memory and enables an exact access to the memory block. - To read the data memory bit by bit (e.g. reading the measuring values of one channel only or reading when memory depth is reduced), the start can be changed. C0740/2 1 - Enables Read memory. - Allows access to the memory to read the data. 0 - Inhibits Read memory - Inhibits access to the memory. The access must be inhibited after every reading of data. Info on the Detailed information about the function block function block C0741/1 Version of the function block (e.g. 120: version 1.20) C0741/2 Data memory size ( bytes) C0741/3 Data width of the measuring values (1 byte / 2 bytes) C0741/4 Number of measuring channels available (1... 4) Data block length C Indicates the data block length for reading the data memory. - When reading the data memory, the FB transmits the measuring values as blocks, i.e. each reading access transmits at least 8 bytes/block (= data block length). - Data block length for 9300 controller = 8 bytes Data block read C Indicates reading from the data memory - With each reading access to this code, a data block (8 bytes) is transmitted from the drive to the visualisation system. The system starts at the beginning (C0740/1) and counts automatically block by block. Memory size C Set depth of the data memory - Max. size of the data memory: 8192 measuring values bytes (C0744 = 6) - Min. size of the data memory: 512 measuring values 1024 bytes (C0744 = 0) - Change of the memory depth with 512 measuring values/steps - An optimum adaptation of the memory depth to the corresponding measuring task reduces the data transmission time.

24 Configuration 4.3 Communication protocol This chapter describes the communication between the FB OSZ in the controller and the visualisation on the PC based on the LECOM-A/B protocol (see Operating Instructions for LECOM-A/B fieldbus module 2102) Data format of the codes Except of C0743 (read data block) all codes are accessed with the data format VD. This applies to writing and reading. C0743 is accessed with the data format VO. With C0743 the data memory of the FB OSZ can be read. Before the reading access must have been enabled under C0740/2. C0743 can be read only Organisation of the data memory The data memory of the FB OSZ is a ring memory with max bytes. The whole memory is subdivided between the active channels (see FIG 4-4). The measuring values have a data width of 2 bytes. Thus, the memory can file max measuring values. If the max. memory depth is reduced (under C0744), this reduced memory is subdivided between the active channels, too Ring memory block of a channel with circulating memory index channel 2 channels 3 channels 4 channels FIG 4-4 Organisation of the data memory 4-6 OSZBA0299

25 Configuration Channel 1 Channel 2 Channel 1 assigned Channel 3 Channel 4 Channel 2 FIG 4-5 Organisation of the data memory with 2 and 4 channels and reduced memory depth The start is determined in the memory for every channel. If the memory depth is reduced, gaps occur between the data ranges. These gaps must be skipped when reading the data (see FIG 4-5). Thus, optimum data transmission times can be achieved. With the setting of a start for reading the data memory, the gap will be skipped. The starts for the individual memories have the following values: Number of channels Start (value for C740/1) for channel 1 = 0 for channel 2 = for channel 1 = 0 for channel 2 = 5460 for channel 3 = for channel 1 = 0 for channel 2 = 4096 for channel 3 = 8192 for channel 4 = OSZBA

Example of a C programming for the data conversion from HIGH byte and LOW byte into an integer value: for (i=0;i < *LCM_AB_Test_read.LCM_AB_value_len;i=i+2) { measuring value_array[k] = ((int)lcm_ab_test_read.lcm_ab_value_ptr[i+1] << 8) LCM_AB_Test_read.LCM_AB_value_ptr[i]; k++;/*fill the measuring value memory*/ } 4-8 OSZBA0299

27 Configuration Measuring value required to reconstruct a picture Since the measuring values for each channel are stored in the ring memory, the data read out do not automatically have a picture start and picture end. The information about picture reconstruction can be obtained from C0749. The measuring value number for - the trigger instant (C0749/2), - the end instant (C0749/3) and - the cancel instant (C0749/1) enable the visualisation system to reconstruct the picture. If the measurement is cancelled, a cancel instant will be set. The end instant is then 0.
