Controlling with the C7-613

Overview
The user program controlling the process runs on the C7-613.
The following functional units determine the mode of operation of the C7-613:
Loading memory
The loading memory is positioned on the Micro Memory Card (MMC). It includes
the user program, the FBs needed for the HMI functions, and the DBs where the
configuration data for the screens, messages, and info texts are stored.
Processor
The processor executes the program cyclically:
• At the beginning of the cycle, the processor reads the signal states on all inputs
and generates a process image of the inputs (PII).
• The program is executed step-by-step using internal counters, bit memory, and
timers.
• The processor stores the calculated signal states in the process output image
(POI). At the end of the cycle, the process image is transmitted to the outputs.
Configuring and Programming
You configure and program the C7-613 by means of STEP 7 as of V 5.2 + Service
Pack 1 + Hardware Update C7-613 V2.0. The programming languages available
for the system are specified in the S7-300 Programmable Controllers, CPU Data:
CPU 31xC and CPU 31x" manual.
Prerequisite:
STEP 7 is installed on a programming device or PC under Windows 2000 or XP.
You have two possibilities of configuring and programming the C7-613:
• The programming device or PC is not connected to the C7-613:
You store the configuration and the user program on a Micro Memory Card and
plug it afterwards into the C7-613.
• The programming device or the PC is connected to the C7-613 via the MPI
interface:
You download the configuration and the user program directly into the C7-613.
