Status Input diagnostics
If the encoder has an error signal or status output, this can be connected to the "Status Input" input of the terminal and evaluated. The input is 5 V compatible.
The error signal or status output at the encoder is usually implemented with negative logic. This is indicated by the terminal as follows:
Encoder | EL5131 | ||
|---|---|---|---|
Alarm output | Status Input | Status Input LED | Meaning |
HIGH level / output open | TRUE | Off | e.g. encoder OK |
LOW level / PullDown - level is actively pulled down to LOW | FALSE | Red | e.g. encoder faulty |
If an overvoltage is present at the Status Input, it is displayed as follows:
Fault diagnosis in case of overvoltage at the Status Input | Display |
|---|---|
DiagMessage, type "Error", text ID 0x8315 | Error status input (channel n) |
0xA0n0:05 "Error input status" | TRUE |
LED: Status Input Ch. n | Red |
