WAGO-I/O-SYSTEM 750 I/O Modules 227758-874/000-131 WAGO-I/O-IPC-C6ManualVersion 1.0.018.2.1.4 2 Channel Digital Input Module with Diagnostics and Output ProcessData750-418,753-418The digital input module supplies a diagnostic and acknowledge bit for each inputchannel. If a fault condition occurs, the diagnostic bit is set. After the faultcondition is cleared, an acknowledge bit must be set to re-activate the input. Thediagnostic data and input data bit is mapped in the Input Process Image, while theacknowledge bit is in the Output Process Image.Table 84: 2 Channel Digital Input Module with Diagnostics and Output Process DataInput Process ImageBit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0Diagnosticbit S 2Channel 2Diagnosticbit S 1Channel 1Data bitDI 2Channel 2Data bitDI 1Channel 1Output Process ImageBit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0Acknowledge-ment bit Q 2Channel 2Acknowledge-ment bit Q 1Channel 10 018.2.1.5 4 Channel Digital Input Modules750-402, -403, -408, -409, -414, -415, -422, -423, -428, -432, -433, -1420, -1421,-1422753-402, -403, -408, -409, -415, -422, -423, -428, -432, -433, -440Table 85: 4 Channel Digital Input ModulesInput Process ImageBit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0Data bitDI 4Channel 4Data bitDI 3Channel 3Data bitDI 2Channel 2Data bitDI 1Channel 118.2.1.6 8 Channel Digital Input Modules750-430, -431, -436, -437, -1415, -1416, -1417753-430, -431, -434Table 86: 8 Channel Digital Input ModulesInput Process ImageBit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0Data bitDI 8Channel 8Data bitDI 7Channel 7Data bitDI 6Channel 6Data bitDI 5Channel 5Data bitDI 4Channel 4Data bitDI 3Channel 3Data bitDI 2Channel 2Data bitDI 1Channel 1
