Explanation of Table 6-12
•
Representation: Two's complement
•
Overrange condition for values outside the nominal range
•
Overflow for values from 500 mV above the nominal range
•
Configuration aids
- Set the jumpers on the module for the measuring range (0 to 1 V, 0 to 10 V, 0 to 20 mA)
- Configure channel type 5 or 6 with COM 115F
•
This type of measured value representation can also be set for measuring ranges 0 to 10 V and
0 to 20 mA
•
FB 250 recognizes wire break with the "DRAK" parameter (method , 6.5)
FB 250 ANEI responds to errors according to I/O type:
- I/O type 13 (nonsafety-related):
- I/O types 14/15/16 (safety-related):
