Table 46: Displays of output LEDs
Output LEDs (Q1–Q4) Meaning
Green (1 Hz)
Synchronous with the red MS LED
Output has a test error.
Output is switched off.
Green (1 Hz)
Output is switched off.
Device state and LED displays in the standard input/output modules

Table 47: Displays of the MS LED
MS LED Meaning Info
Supply voltage outside of operating range Check supply voltage at terminals A1 and A2.
/
Red flashing
(1 Hz)
Repairable external error Check cable of flashing inputs and outputs.
If all output LEDs are flashing, check the
supply voltage of terminal A1 and A2 for this
module.
Green flashing
(1 Hz)
System in the stop state and waits for start
command or the voltage supply to A1 / A2 is
outside the range of 16.8V to 30V. Start the application in samosPLAN 6.
Check voltage supply to A1.
Green
System in the run state and the voltage supp-
ly to A1 is within the range of 16.8V to 30V.
Red flashing
(1 Hz)
Invalid configuration
Red flashing
(2 Hz)
Critical error (type 3) in the system; suspected
in this module. Application has been stopped. Switch supply voltage off and back on.
If the error has not been eliminated after this
has been done multiple times, then replace
module.
In order to contain the module affected, use
the diagnostics display in samosPLAN
6.
Red
Critical error in the system; suspected in a
different module. Application has been stop-
ped.
Switch supply voltage off and back on.
If the error has not been eliminated after this
has been done multiple times, then replace
module in which the red LED is flashing (2
Hz).
In order to contain the module affected, use
the diagnostics display in samosPLAN
6.
Table 48: Displays of input LEDs
Input LEDs (I1–I4 and IY5-IY8) Meaning
Signal level at the input terminal is 0 V.
Inputs actuated.
Green
Signal level at the input terminal is 24V.
Input is not actuated.
