4.4.3 Addressing periphery modulesThe CPU 013-CCF0R00 provides an periphery area (address 0 ... 2047) and a processimage of the in- and outputs (each address default 0 ... 127). The size of the processimage can be adjusted via the parametrization.Ä Chap. 4.8 ‘Setting standard CPUparameters’ page 78The process image is updated automatically when a cycle has been completed. Theprocess image is divided into two parts:n Process image of the inputs (PII)n Process image of the outputs (PIQ)1 Periphery area: 0 ... 127 (default)2 Periphery area : 0 ... 20473 Process image of the inputs (PII): 0 ... 1274 Process image of the inputs (PII): max. 20475 Process image of the outputs (PIQ): 0 ... 1276 Process image of the outputs (PIQ): max. 2047Up to 64 SLIO modules can be connected to a SLIO CPU. This sum includes power andclamp modules.You may access the modules with read respectively write accesses to the peripheralbytes or the process image. To define addresses a hardware configuration may be used.For this, click on the properties of the according module and set the wanted address.If you do not like to use a hardware configuration, an automatic addressing is established.Here the address assignment follows the following specifications:n Starting with slot 1, the central plugged modules are assigned with ascending logicaladdresses.n The length of the memory area corresponds to the size of the process data of theaccording module. Information about the sizes of the process data can be found inthe according manual of the module.n The memory areas of the modules are assigned without gaps separately for input andoutput area.n Digital modules are mapped starting at address 0 and all other modules are mappedstarting from address 256. ETS modules are mapped starting from address 256.n As soon as the mapping of digital modules exceeds the address 256, by regardingthe order, these are mapped starting from address 256.Max. number of modulesDefine addresses by hard-ware configurationAutomatic addressingVIPA System SLIODeployment CPU 013-CCF0R00Addressing > Addressing periphery modulesHB300 | CPU | 013-CCF0R00 | en | 19-3068
