I/O Link
Communicates, from a remote chassis, with the programmable
controller via an I/O adapter module (1771ĆASB)

This section provides an overview of the programming interface and
capabilities of the control coprocessor.
ATTENTION: Control-coprocessor programs that
unintentionally write to memory outside their own data space
can corrupt memory for other applications or corrupt system
memory. We strongly recommend that development be done in
an offline or non-critical context.
User Interface
You can develop programs and communicate with the control coprocessor
using a DOS-based computer or an ASCII terminal. See Table 1.D.
