请教大侠西门子ADI4与840DI的通讯:我用STEP7组态下载到840DI的PLC中,在下载硬件组态后就报警,SF灯亮,ADI4的数据交换的绿亮,但在线诊断ADI4时显示 Module configured, but not available Preset/Actual mismatch: (inserted and configured module types are not the same) - Expected type: DP Slave (compact) (6SN1118-xN00-0AAx) - Current type: Not available 后ADI4的数据交换灯变为红色,如组态时不用ADI4只是用PP72/48,则完全正常,参数我选择报文3,请大侠指教下,谢谢
