The Task Flags will be cleared in the following cases, regardless of the status
of the IOM Hold Bit.
1. The operating mode is changed from PROGRAM mode to RUN/MONITOR
2. The PLC’s power supply is cycled.
The Task Flags cannot be force-set and force-reset.
These flags include the Arithmetic Flags such as the Error Flag and Equals
Flag which indicate the results of instruction execution. In earlier PLCs, these
flags were in the SR Area.
The Condition Flags are specified with labels, such as CY and ER, or with
symbols, such as P_Carry and P_Instr_Error, rather than addresses. The sta-
tus of these flags reflects the results of instruction execution, but the flags are
read-only; they cannot be written directly from instructions or Programming
Devices.
P_.
All Condition Flags are cleared when the program switches tasks, so the sta-
tus of the ER and AER flags are maintained only in the task in which the error
occurred.
The Condition Flags cannot be force-set and force-reset.
The following table summarizes the functions of the Condition Flags, although
the functions of these flags will vary slightly from instruction to instruction.
