Dear All, I need help you regarding Step7 IO redundancy .I am using step7 and i have redundant signal for DI,DO,AI and AO. I am using redundant IO CGP 5.2. Digital input and output working fine. But Analog Input show some problem like when i disconnect the primary AI module from rack. The redundant second module working but lower address was not update with higher signal value.If i again connect the first AI module and disconnect the second AI module value both module show value is 0. If i disconnect the front connect from 1st module of AI.The second module was update to the lower address that is fine. I am calling library in OBs as bellow RED IN: OB1 and OB35 RED OUT: OB1 and OB35 RED DIAG: OB72,OB82,OB83,OB85 RED INIT: OB72,OB80,OB100,OB102 DEPA: OB83,OB85 In hardware configuration the configuration of process image for all DI,DO,AI and AO are PIP1 and DI and DO in redundancy tab the configuration for "reaction after discripancy" is OR. Kindly advice me to resolve the analog redandacy problem as soon as possible. Thanks in advance .... Attachmentredundant_IO_example_2016_07_31.zip (81 Downloads) |
