Substitute Value
Substitute values are values which are output to the process in the case of faulty
signal output modules or which are used in the user program instead of a process
variable in the case of faulty signal input modules. The substitute values can be
specified in advance by the user (for example, maintain old value)System diagnostics is the detection, evaluation, and reporting of errors occurring
within the programmable controller. Examples of such errors are: program errors or
failures on modules. System errors can be indicated with LED indicators or by
STEP 7.An integral programmable function of the CPU operating system. Can be called in
the user program. SFCs are not loaded as part of the program, because they are
part of the operating system. SFCs do not have a memory function, same as FCs.
System Function Block (SFB)
An itegral function block of the CPU operating system. SFBs are not loaded as part
of the program, because they are part of the operating system. Without memory
function, same as SFCs. You need to create instance DBs for these blocks and
load them into the CPU as part of the user program.The system memory is integrated in the CPU and executed in the form of RAM.
The address areas (timers, counters, bit memory, etc.) and data areas required
internally by the operating system (for example, backup for communication) are
stored in the system memoryUsed to terminate data transfer lines in order to avoid reflections on the bus.
Time-Delay Interrupt
The time-delay interrupt belongs to one of the priority classes in SIMATIC
program processing. It is generated after expiry of a time started in the user
program. A corresponding organization block is then executed.
Time-Of-Day Interrupt
The time-of-day interrupt belongs to a priotity class in SIMATIC program
program execution. It is generated depending on a certain date (or daily) and time
of day (for example, 9:50 or hourly, per minute). A corresponding organization
block is then executed.Timers are an area in the system memory of the CPU. The contents of these timers
are updated by the operating system asynchronously to the user program. You can
use STEP 7 instructions to define the exact function of the timer (for example,
on-delay timer) and start processing it (Start).
Toggle switch
The mode selector is a toggle switch which can be used to set the CPU from RUN
to STOP or reset CPU memoryrent
Sum of currents of all output channels of a digital output module.
U
Ungrounded
Without galvanic connection to ground.
Update interrupt
An update inbterrupt can be generated by a DPV1 slave.
The DPV1 responds with a call of OB56. For detailed information on OB56, refer to
the “System Software for S7-300/ System and Standard Functions”
reference manual.
