  • Page 49: Addressing

    Addressing Principles of Data Transfer Between the DP Master and the IM 151-7 CPU This chapter contains information on the addressing of I/O modules and data transfer between the DP master and the IM 151-7 CPU. The following alternatives are available for addressing the I/O modules: S Slot-oriented address allocation: Slot-oriented address allocation is the default form of addressing, in which STEP 7 allocates a fixed module base address to each slot number.

  • Page 50: Slot-Oriented Addressing Of The I/O Modules

    Addressing Slot-Oriented Addressing of the I/O Modules Slot-Oriented Address Allocation In slot-oriented addressing (default addressing) each slot number in a module is allocated an address area in the IM 151-7 CPU. Depending on the type of I/O module, the addresses are digital or analog (see Table 3-1).

  • Page 51: Addresses Of The Et 200S I/O Modules

    Addressing Address Assignment Depending on the slot, 1 byte is reserved for digital I/Os and 16 bytes are reserved for analog I/Os in the address areas of the IM 151/7 CPU for each I/O module (maximum of 63). The table below indicates the default address assignment for analog and digital modules per slot.

  • Page 53: Data Interchanger With The Dp Master

    Addressing Advantages Advantages of user-defined address allocation: S Optimum utilization of the address areas available, since ”address gaps” between the modules do not occur. S When creating standard software, you can specify addresses that are independent of the configuration of the ET 200S station. Data interchanger with the DP Master User data transfer via an intermediate memory The user data is located in an intermediate memory in the IM 151-7 CPU.
  • Page 54 Addressing Data consistency You define data consistency as byte, word, or overall consistency per address area. Consistency can amount to up to 32 bytes/16 words per address area. DP diagnostic address in STEP 7 When the ET 200S is configured with STEP 7, two diagnostic addresses are set. The ET 200S receives information on the status of the DP master or on a bus interruption by means of these diagnostic addresses (see Section 7.5).

  • Page 56: Addressing Interface In Step 7 V5.1 (Extract)

    When the IM 151-7 CPU is configured with STEP 7 for operation in the S5 or in non-Siemens systems, it is clear that only the logical addresses within the slave CPU are allocated. The addresses are then assigned in the master system using the specific configuration tool of the master system.

    Cycle and Response Times Introduction In this chapter you will learn what make up the cycle and response times of the ET 200S with the IM 151-7 CPU. You can use the PD to read out the cycle time of your user program (see the STEP 7 user manual).

  • Page 166: Component Parts Of The Cycle Time

    Cycle and Response Times Cycle time Cycle time – a definition The cycle time is the time that the operating system requires to process a program cycle – i.e. an OB 1 cycle – as well as all the program sections and system activities interrupting this cycle.

    Cycle and Response Times Extending the cycle time Note that the cycle time of a user program is extended by the following: S Time-controlled interrupt handling S Process interrupt handling (see also Section 9.3) S Diagnostics and error handling (see also Section 9.3) Operating system processing time The operating system execution time for the IM 151-7 CPU is found in Table 9-1.

  • Page 168: Dependency Of The User Program Scanning Time

    Cycle and Response Times User program scanning time: The user program scanning time is made up of the sum of the execution times for the instructions and SFCs called. These execution times can be found in the instruction list. You also have to multiply the user program scanning time by an interface module-specific factor.

    Cycle and Response Times Response time Response time for the ET 200S with the IM 151-7 CPU The response time is the time from the detection of an input signal at the ET 200S with the IM 151-7 CPU to the modification of an associated output signal via the inputs and outputs of the expansion modules.

    Cycle and Response Times Shortest response time The following figure shows you the conditions under which the shortest response time is obtained. Delay of the inputs The status of the observed input changes immediately before reading in the PII. The change in the input signal is therefore taken account of in the PII.

    Cycle and Response Times Longest response time The following figure shows what the longest response time consists of. Delay of the inputs + DP cycle time at the PROFIBUS-DP While the PII is being read in, the status of the observed input changes. The change in the input signal is no longer taken into account in the PII.
