From point-to-point: CP 440, CP441-1 and CP 441-2

Introduction
The point-to-point connection is a high-performance, economic alternative to the
bus systems. It enables the connection of barcode readers, scales and displays,
for example. But it can also be used to interconnect to other automation systems.
Point-to-point with CP 441-1 and CP 441-2
You can select two communication modules (CP) for point-to-point connection:
• CP 440
• CP441-1 with a plug-in interface module
• CP441-2 with two plug-in interface modules
Plug-in interface modules
A variety of interface modules can be plugged into the CP. The following are
available:
• TTY module
