Developing Programs

This chapter describes the library of commands and executable functions
available with the control coprocessor. You will also learn when and
how to use them for communication with a programmable controller.

ATTENTION: Control-coprocessor programs that
unintentionally write to memory outside their own data
space can corrupt memory for other applications or corrupt
system memory. This may cause unpredictable control-
coprocessor operation, including module reset. In a multi-user
environment, a reset naturally affects other users. We strongly
recommend that multi-user development be done in an offline
or non-critical context.
