The following data would be generated in an error record if a memory error (error code 80F1) occurred on 1
April 1998 at 17:10:30 with the error located in the PLC Setup (04 hex).
The following data would be generated in an error record if an FALS error with FALS number 001 occurred on
2 May 1997 at 8:30:15.
Error Codes and Error Flags
Note 1. C101 to C2FF will be stored for FALS numbers 001 to 511.
2. 4101 to 42FF will be stored for FAL numbers 001 to 511.
3. The contents of the error flags for a duplicate number error are as follows:
Bits 0 to 7: Unit number (binary), 00 to 5F hex for Special I/O Units, 00 to 0F hex for CPU Bus Units
Bits 8 to 14: All zeros.
Bit 15: Unit type, 0 for CPU Bus Units and 1 for Special I/O Units.
4. Only the contents of A295 is stored as the error flag contents for program errors.
5. 0000 hex will be stored as the error flag contents.
