4–2 Programming Error Codes
Publication 1771-6.5.88 – July 1997
You read error codes on your programming terminal by examining
system status words in the PLC data table:
• SYS61 = ID of the block that contains the error
• SYS62 = error code
You can interpret most error codes by memorizing 9 basic types and
knowing how the codes are organized.
The 4-digit code, xxyy, has two parts:
• xx = type description
• yy = word in the command block that contains the error
Here we list the type descriptions, each with an example error code.
Type Example Description
02
0222
Outside fixed limits
02 0222
MCC22 is out of range. Valid range is 00000 ≤ MCC22 ≤ 00099.
03
Cannot be equal
03
0311
MCC11 is equal to MCC12. They must not be equal.
Outside range established by another entry
04
0427
MCC27 is out of range.
If MCC28 is non-zero, MCC27 must be within
MCC23
≤ MCC27 ≤ MCC28.
If MCC28 is zero, MCC27 must be within
MCC23
≤ MCC27 ≤ MCC24.
Bit selection error
05
0502
You configured the module for 4/4 I/O by MCC02-B03=1.
Therefore, MCC02-B04=1 and MCC02-B05=1 is illegal.
Block-related configuration error
06 0609
Your CPC10 must be zero because of invalid FCC.
(SYS15-B02 = 0)
07
0712
Required non-zero entry
07 0712
IPC12 cannot be zero when IPC14 > 00000.
08
0816
Entry must be zero
08 0816
IPC16 must be 00000 when IPC12 = 00000.
Entry combination error (group is outside fixed limits)
09 0960
Your entry combination is illegal:
IPC60 = IPC61 = IPC62 = IPC63 = 00000.
Error in entry order
10
1015
IPC is not in decreasing positional order.
If non-zero, IPC15 must be less than IPC11.
