EM 277 PROFIBUS-DP PROFIBUS DP is an open, international fieldbus communication
Module standard that allows a broad range of intelligent devices from
various manufacturers to communicate rapidly and efficiently.
This reduces wiring costs as well as start-up and maintenance
expenses.
EM 277 PROFIBUS-DP module allows connection of the
S7-200 CPU (CPU 222 and above) to a PROFIBUS-DP network
as a slave.

CP 243-2 AS-Interface Actuator Sensor Interface (AS-Interface or AS-i) is a system
Master Module for networking field devices such as sensors and actuators
with control and operator interface devices. AS-i replaces the
extensive parallel wiring often used to connect sensors and
actuators to controllers with a simple 2-core cable. The cable is
designed so that devices can only be connected correctly.
CP 243-2 AS-Interface Master module allows connection of
the S7-200 CPU (CPU 222 and above) to a AS-I network as a
master.
