41129 (bit0–bit7) |
Device status (error overview; see the detailed diagnostic information for the specific ports): Bit0: Short-circuit error (short circuit on master/slave) Bit1: Cascaded module error (a cascaded slave has a module short circuit) Bit 2: station configuration error (total byte count mismatch or port software configuration inconsistent with the hardware configuration) Bit3: Reserved Bit4: Ua undervoltage Bit5: Ua overvoltage Bit6: Us undervoltage Bit7: Us overvoltage |

IO-Link connection status: (Bit0: Port X01; Bit1: Port X02, and so on) 0: Not connected 1: Connected |
R |
|
|
41130 (bit8–bit15) |
Configuration status: (Bit8: Port X01; Bit9: Port X02, and so on) 0: Configuration correct 1: Configuration error
Configuration error self-check: (1) Port configuration bytes are less than the slave attributes (input/output bytes) or the configuration exceeds 32 bytes (2) The configured port model is inconsistent with the actually connected model (including inconsistency between the extension modules configured by extension-capable slaves and the actual modules) (3) Port type inconsistent with the slave type, e.g. Class B type without Ua connected (undervoltage) |
