³
STEP 7 Application
Sum of the currents of all output channels of a digital output module.
Data transmission rate (bit/s).
U
Without galvanic connection to
³
ground.
The user memory contains
³
logic blocks and
³
data blocks of the user
program. The user memory is integrated in the C7 CPU as flash memory. In
general, however, the user program is executed from the
³
work memory of
the C7 CPU.
The user program contains all the statements and declarations and the data
required for signal processing to control a plant or a process. The program is
linked to a programmable module (for example, C7 CPU, FM) and can be
structured in the form of smaller units (blocks).
V
Voltage-dependent resistor.
W
The work memory is a RAM in the
³
C7 620 which the processor accesses
while executing the program.
