Error Details
1
Source/destination device is out of range
2
MUL result is out of data type range.
3
DIV result is out of data type range, or division by 0.
4
BCDLS has S1 or S1+1 exceeding 9999.
5
HTOB(W) has S1 exceeding 9999.
6
BTOH has any digit of S1 exceeding 9.
7
HTOA/ATOH/BTOA/ATOB has quantity of digits to convert out of range.
8
ATOH/ATOB has non-ASCII data for S1 through S1+4.
9
WKTIM has S1, S2, and S3 exceeding the valid range.
S1: 0 through 127
S2/S3: Hour data 0 through 23, minute data 0 through 59
S2/S3 can be 10000.
WKTBL instruction is not programmed or WKTIM instruction is executed before WKTBL instruction
when 1 (additional days in the week table) or 2 (skip days in the week table) is set for MODE in the
WKTIM instruction.
10
WKTBL has S1 through Sn out of range.
Month: 01 through 12
Day: 01 through 31
11
DGRD data exceeds 65535 with BCD5 digits selected.
12
CVXTY/CVYTX is executed without matching XYFS.
XYFS and CVXTY/CVYTX have the same S1, but have different data types.
13
CVXTY/CVYTX has S2 exceeding the value specified in XYFS.
14
Label in LJMP, LCAL, or DJNZ is not found.
15
TXD/RXD is executed while the RS232C port 1 or 2 is
not
set to user communication mode.
16
PID instruction execution error (see page 14-4 (Advanced.Vol.)).
17
Preset value is written to a timer/counter whose preset value is designated with a data register.
18
Attempt was made to execute an instruction that cannot be used in an interrupt program:

DI, EI, XYFS, CVXTY, CVYTX, PULS, PWM, RAMP, ZRN, PID, DTML, DTIM, DTMH, DTMS, TTIM, RUNA, and
STPA (see page 5-35).
19
Attempt was made to execute an instruction that is not available for the PLC.
20
PULS, PWM, RAMP, or ZRN has an invalid value in control registers.
21
DECO has S1 exceeding 255.
22
BCNT has S2 exceeding 256.
23
ICMP>= has S1 < S3.
24
— Reserved —
25
BCDLS has S2 exceeding 7.
26
DI or EI is executed when interrupt input or timer interrupt is not programmed in the Function Area Set-
tings.
27
Work area is broken when using DTML, DTIM, DTMH, DTMS, or TTIM.
28
S1 for trigonometric function instruction is invalid.
