WAGO-I/O-SYSTEM 750 I/O Modules 243758-874/000-131 WAGO-I/O-IPC-C6ManualVersion 1.0.0750-635,753-635The above Digital Pulse Interface module has a total of 4 bytes of user data inboth the Input and Output Process Image (3 bytes of module data and 1 byte ofcontrol/status). The following table illustrates the Input and Output ProcessImage, which have 2 words mapped into each image. Word alignment is applied.Table 114: Digital Pulse Interface Modules 750-635Input and Output Process ImageByte DestinationOffset High Byte Low Byte Description0 D0 C0/S0 Data byte Control/statusbyte1 D2 D1 Data bytes18.2.5.8 DC-Drive Controller750-636The DC-Drive Controller maps 6 bytes into both the input and output processimage. The data sent and received are stored in up to 4 input and output bytes(D0 ... D3). Two control bytes (C0, C1) and two status bytes (S0/S1) are used tocontrol the I/O module and the drive.In addition to the position data in the input process image (D0 … D3), it ispossible to display extended status information (S2 … S5). Then the three controlbytes (C1 … C3) and status bytes (S1 … S3) are used to control the data flow.Bit 3 of control byte C1 (C1.3) is used to switch between the process data and theextended status bytes in the input process image (Extended Info_ON). Bit 3 ofstatus byte S1 (S1.3) is used to acknowledge the switching process.Table 115: DC-Drive Controller 750-636Input Process ImageByte DestinationOffset High Byte Low Byte Description0 S1 S0 Status byte S1 Status byte S01 D1*) / S3**) D0*) / S2**)Actual position*)/ Extended statusbyte S3**)Actual position(LSB) / Extendedstatus byte S2**)2 D3*) / S5**) D2*) / S4**)Actual position(MSB) /Extended statusbyte S3**)Actual position*)/ Extended statusbyte S4**)*) ExtendedInfo_ON = ‘0’.**) ExtendedInfo_ON = ‘1’.
