Bit A40209 is turned ON when the Units mounted in the system disagree with the
I/O table registered in the CPU. To ensure proper operation, PC operation
should be stopped, Units checked, and the I/O table corrected whenever this
flag goes ON.
Bit A40212 is turned ON if the content of an indirectly addressed DM word is not
BCD when BCD is specified in the PC Setup.
The contents of indirectly addressed DM words can be set to either binary or
BCD with the PC Setup. Binary addresses will access memory according to in-
ternal I/O memory addresses. BCD will access other DM words according to DM
Area addresses. If binary addresses are used, this flag will not operate.
Bit A40213 is turned ON if there is no destination for a JMP(004) instruction.
Bit A40214 is turned ON if an error is detected during the duplex power supply
error check. Refer to 3-6-23 Power Supply Unit OFF/Error Flags for details on
the flags that indicate which Power Supply Unit is the cause of the error.
Bit A40215 is turned ON when the FAL(006) instruction is executed. The FAL
number is then written to words A430 to A461. Bits from A43001 to A46115 cor-
respond consecutively to FAL numbers 001 to 511
Bits A40300 to A40308 are turned ON to indicate the memory area in which a
memory error has occurred. The bits correspond to memory areas as follows:
00: Program Memory
01: Memory Card
02: I/O Memory
03: EM
04: PC Setup
Bit A40309 is turned ON when an error occurs during the transmission of the
program from the Memory Card when power is turned ON. An error can occur
because the AUTOEXEC file is missing, the Memory Card is not installed, or the
System Protect setting is ON.
Bits A41900 through A41907 are turned ON when Expansion Racks #0 through
#7, respectively, are recognized by the CPU.
Bit A42314 is turned ON when a CPU Bus Unit is not set to an acceptable unit
number (0 to 15).
Bit A42315 is turned ON when a parity error occurs with CPU bus links.
