Generating a Non-fatal System Error (CS1-H, CJ1-H, CJ1M, and CS1D
CPU Units Only)
When CIO 000000 is ON in the following example, FALS(007) will generate a
Too Many I/O Points Error (too many Expansion Racks connected, 9 Racks in
this case). In this case, dummy FAL number 10 is used and the corresponding
value (000A hex) is stored in A529.
1. The specified error code (80E1) will be written to A400 if it is the most se-
rious error.
2. The error code and the time/date that the error occurred will be written to
the Error Log Area (A100 through A199).
3. The Too Many I/O Points Flag (A40111) will be turned ON.
4. The CPU Unit's ERR Indicator will light and PLC operation will stop.
5. A message (TOO MANY I/O PNT) will be displayed at the Programming
