To scan whether there is a short-circuit or an overload on an output of a
device with transistor outputs, use the internal inputs I15, I16, and use R15,
R16 if an expansion unit is connected.
• EASY82 .-D.-T..:
• I16: Group fault alarm for outputs Q1 - Q4.
• I15: Group fault alarm for outputs Q5 - Q8.
• EASY620-D.-TE (expansion unit):
• R16: Group fault alarm for outputs S1 - S4.
• R15: Group fault alarm for outputs S5 - S8.
• easy800-SWD
• I14: as group alarm out of function; permanently set to 1.
• I16: Group alarm for the outputs Q1/Q2
If both terminals are configured as inputs I3/I4, I16 is always 0.
State
Fault alarms
No fault present
Fault present on at least one output
￫
I15 and I16 can only be used on easy800 variants with transistor
outputs.
The following examples show the use of the group fault alarm I16 for
checking the function of the transistor outputs Q1...Q4 on easy800 standard.
Example 1: Output with fault indication
I 01----M 16------------------Ä Q 01
I 16--------------------------S M 16
Figure 218:Circuit diagram for fault output via I16
The above circuit diagram functions as follows:
If a transistor output indicates a fault, I16 sets marker M16. The N/C contact
of M16 switches off output Q1. M16 can be reset by switching the easy800
supply voltage off and on so that the N/C contact closes again.
I15 or I16, R15 or R16
0 = switched off (N/O)
1 = switched on (N/O)
