2.2 Programming
The CL200 is programmed with the aid of a PC via the serial COM port.
With the use of the PC, the PLC program can also be written without requi-
ring the physical presence of the controller.
The CL200 provides the following options for storing the PLC program:
D Battery backed RAM memory
D Flash EPROM memory
D MemoryCard
Program Structure
The PLC program is subdivided into clearly defined and technologically allo-
cated program modules.
Programming
The PLC program is produced with the use of the Bosch proprietary WinSPS
software application.
The PLC program can be produced in the form of
D IL instruction list
D LD ladder diagram
D FUD function diagram
D SFC sequential function chart
with optional use of symbolic or absolute operands.
The programming language is based on DIN 19239.
PLC program documentation
The clearly structured and easily understood PLC program documentation
providing cross-reference lists supports the user in the case of quick system
startup, system troubleshooting, or when adapting the controller to new ap-
plications.
Both in the form of the screen display of the programming unit and as hard-
copy, the PLC program documentation provides a substantial rate of com-
ments.
