Mode of operation

• Creating an FM 352-5 program with STEP 7 in LAD or FBD.
• Implementation of simulations and tests on an S7-CPU or with the PLCSIM software simulation.
• Compiling an FM 352-5 program in destination code for the FM 352-5.
• Download the data directly to the module, either directly through the S7-CPU or using an MMC card.
• In RUN position: The FPGA processed the program in a cycle of 1 µs duration.
• Data exchange with the CPU is carried out via the 16-byte I/O interface.
  

Parameter settings

Parameters are assigned with STEP 7 or COM PROFIBUS and standardized *.GSE files. In order to accelerate the switch-on procedure, the *.GSE file is already operable.
