Description
E003
SOFTWARE
TIME-OUT
If the program scan time exceeds the time allotted to the watchdog timer, this
error will occur. SP51 will be on and the error code will be stored in V7755. To
correct this problem use AUX 55 to extend the time allotted to the watchdog
timer.
E004
INVALID
INSTRUCTION

had a parity error. Performing a program download to the CPU in an
electrically noisy environment can corrupt a program’s contents. Clear the
CPU program memory, and download the program again.
E099
PROGRAM
MEMORY
EXCEEDED
If the compiled program length exceeds the amount of available CPU RAM
this error will occur. SP52 will be on and the error code will be stored in
V7755. Reduce the size of the application program.
E151
BAD COMMAND
A parity error has occurred in the application program. SP44 will be on and
the error code will be stored in V7755 .This problem may possibly be due to
electrical noise. Clear the memory and download the program again. Correct
any grounding problems. If the error returns replace the Micro PLC.
E155
RAM FAILURE
A checksum error has occurred in the system RAM. SP44 will be on and the
error code will be stored in V7755. This problem may possibly be due to a low
battery, electrical noise or a CPU RAM failure. Clear the memory and
download the program again. Correct any grounding problems. If the error
returns replace the CPU.
E210
POWER FAULT

Refer to the Chapter 5 for details on these instructions. SP52 will be on and
the error code will be stored in V7755.
E406
MISSING IRT
An interrupt routine in the program does not end with the IRT instruction.
SP52 will be on and the error code will be stored in V7755.
E421
DUPLICATE STAGE
REFERENCE
Two or more SG or ISG labels exist in the application program with the same
number. A unique number must be allowed for each Stage and Initial Stage.
SP52 will be on and the error code will be stored in V7755.
E422
DUPLICATE LBL
REFERENCE
Two or more LBL instructions exist in the application program with the same
number. A unique number must be allowed for each and label. SP52 will be
on and the error code will be stored in V7755.
E431
INVALID ISG/SG
ADDRESS
An ISG or SG instruction must not be placed after the end statement (such as
inside a subroutine). SP52 will be on and the error code will be stored in
V7755.

Description
E436
INVALID INT
ADDRESS
An INT must be programmed after the end statement, not in the main body of
the program. SP52 will be on and the error code will be stored in V7755.
E438
INVALID IRT
ADDRESS
An IRT must be programmed after the end statement, not in the main body of
the program. SP52 will be on and the error code will be stored in V7755.
E440
INVALID DATA
ADDRESS
Either the DLBL instruction has been programmed in the main program area
(not after the END statement), or the DLBL instruction is on a rung containing
input contact(s).
E441
ACON/NCON
An ACON or NCON must be programmed after the end statement, not in the
main body of the program. SP52 will be on and the error code will be stored
in V7755.
E451
BAD MLS/MLR
MLS instructions must be numbered in ascending order from top to bottom.
E452
X AS COIL
An X data type is being used as a coil output.
