n During the configuration, make sure that the parameters CHANNEL_IN andCHANNEL_OUT of the FBs are correctly interconnected.– CHANNEL_IN is to be interconnected to the input data of the Acyclic channel ofthe motion module.– CHANNEL_OUT is to be interconnected to the output data of the Acyclic channelof the motion module.Starting from the base address, the start address of the Acyclic channel for the input andoutput data can be reached via the following offset:n 054-1BA00: FM 054 - Stepper: Base address + 26n 054-1CB00: FM 054 - 2xDC: Base address + 50n 054-1DA00: FM 054 - Pulse Train RS422: Base address + 26Example with base address 256:CHANNEL_IN :=P#I 282.0 BYTE 10 // Base address 256 + 26CHANNEL_OUT :=P#Q 282.0 BYTE 10 // Base address 256 + 26Please note that you specify a length of 10byte, although the Acyclicchannel internally uses 8byte!12.3.2 FB 320 - ACYC_RW - Acyclic access to the System SLIO motion moduleWith this block you can access the object dictionary of the System SLIO motion modulesby means of your user program. Here the block uses an acyclic communication channelbased on a request/response sequence. This is part of the input/output area of motionmodule.The following System SLIO motion modules are supported:n 054-1BA00: FM 054 - Steppern 054-1CB00: FM 054 - 2xDCn 054-1DA00: FM 054 - Pulse Train RS422Due to the FB 321 internally calls the FB 320 and both blocks access thesame database, for each channel (if multi-channel) you can use only oneof these blocks in your user program! Also this block must be called percycle only once!The data exchange with the motion module must be consistent over thelength of the input or output data! It is recommended to control it via theprocess image. You can also use SFC 14 and 15 to consistently read andwrite the input or output data.ParametersParameter Declaration Data type DescriptionREQUEST IN BOOL The job is started with edge 0-1.MODE IN BYTE Enter 0x01 for the acyclic protocolInterconnecting the FBsDescriptionVIPA SPEED7 Device SpecificMotion Modules > FB 320 - ACYC_RW - Acyclic access to the System SLIO motion moduleHB00 | OPL_SP7 | Operation list | en | 18-30 273
