Diagnosis¶
Structure of the Diagnosis Block
| Byte Number | Description | Possible Values |
|---|---|---|
| 1 | Diagnosis Byte, slot number | 31 = CI502-PNIO (e. g. error at integrated 8 DI / 8 DO) 1 = 1st connected S500 I/O Module … 10 = 10th connected S500 I/O Module |
| 2 | Diagnosis Byte, module number | According to the I/O bus specification passed on by modules to the fieldbus master |
| 3 | Diagnosis Byte, channel | According to the I/O bus specification passed on by modules to the fieldbus master |
| 4 | Diagnosis Byte, error code | According to the I/O bus specification Bit 7 and bit 6, coded error class 0 = E1 1 = E2 2 = E3 3 = E4 Bit 0 to bit 5, coded error description |
| 5 | Diagnosis Byte, flags | According to the I/O bus specification Bit 7: 1 = coming error Bit 6: 1 = leaving error |
| 6 | Reserved | 0 |
In cases of short circuit or overload, the digital outputs are turned off. The modules performs reactivation automatically. Thus an acknowledgement of the errors is not necessary. The error message is stored via the LED.

Remarks:
| 1) | In AC500 the following interface identifier applies: “-” = Diagnosis via bus-specific function blocks; 0 … 4 or 10 = Position of the Communication Module;14 = I/O bus; 31 = Module itself The identifier is not contained in the CI502-PNIO diagnosis block. |
| 2) | With “Device” the following allocation applies: 31 = Module itself, 1..10 = Expansion module |
| 3) | With “Module” the following allocation applies dependent of the master: Module error: 31 = Module itself Channel error: Module type (1 = AI, 2 = DO, 3 = AO) |
| 4) | This message appears, if externally voltages at one or more terminals DC0…DC7 oder DO8…DO15 cause that other digital outputs are supplied through that voltage (voltage feedback, see description in Electrical Connection CI522-MODTCP. All outputs of the apply digital output groups will be turned off for 5 seconds. The diagnosis message appears for the whole output group. |
| 5) | The voltage at digital outputs DC0…DC7 and accordingly DO8…DO15 has exceeded the process supply voltage UP3 CI522-MODTCP. Diagnosis message appears for the whole module. |
| 6) | This message appears, if the output of a channel DC0…DC7 or DO8…DO15 should be switched on while an externally voltage is connected. In this case the start up is disabled, as long as the externally voltage is connected. Otherwise this could produce reverse voltage from this output to other digital outputs. This diagnosis message appears per channel. |
| 7) | Short circuit: After a detected short circuit, the output is deactivated for 2000ms. Then a new start up will be executed. This diagnosis message appears per channel. |
| 8) | In case of an I/O module doesn’t support hot swapping, do not perform any hot-swap operations (also not on any other terminal units (slots)) as modules may be damaged or I/O bus communication may be disturbed. |
| 9) | Diagnosis for hot swap available as of version index F0. |
