There is a detected wiring error.
Ext. diagnosis |
Meaning |
---|---|
|
The affected output is short circuited or overloaded. For outputs of a Lexium 62, there is no special diagnostic message stating that the supply voltage of the OnBoard I/O modules is not connected.
Therefore, when setting an output of a Lexium 62, this diagnostic message
|
Intern / FALSE
this message is assigned to the object of the DIO8 module. An assignment to an output is not possible. If PowerSupply = External / TRUE
, then the message is assigned to the relevant output.
Ext. diagnosis |
Meaning |
---|---|
Openload |
The output is not connected or only slightly loaded.
(Openload detection is not possible for Lexium 62 and Lexium 62 ILM because it is not supported by hardware.) |
PowerFail |
The external power supply of the digital output was not connected. The supply of the digital output is verified if at least one bit is set to 1 in the
|
PowerFail (BT-4/ENC1) |
The power supply of the encoder is too low. Parameter EncPowerSupply = Intern / FALSE: Short-circuit of the power supply (pins 5 and 9) of the connected encoder or inoperable bus terminal BT-4/ENC1 Parameter EncPowerSupply = Extern / TRUE: There is no or not enough power at the X5 plug connector or there is a short-circuit of the power supply (pins 5 and 9) of the connected encoder.
|
PowerFail (BT-4/ENC1) |
A SinCos encoder (physical encoder) was entered in the PLC configuration, but no SinCos encoder is recognized at connector X2 or X3 of BT-4/ENC1.
|
type not supp. |
The connected encoder type is not supported by the system. Connect an encoder supported by the system. |
out <-> out |
Power is supplied externally to the connectors X2, X3, or X4 (pin 5 and 9) of the bus terminal BT-4/ENC1. The connector for the incremental encoder output may have been plugged into an encoder input. Verify and correct if necessary the assignment of the encoder connectors. |
IncIn <- IncIn |
Power is supplied from both sides.
