PROFIBUS

PROFIBUS is used for exchanging data through the user program with other

communications partners through the PROFIBUS network:
●  With CM 1242-5, the CPU operates as a PROFIBUS DP slave.
●  With CM 1243-5, the CPU operates as a PROFIBUS DP master class1.
●  PROFIBUS DP Slaves, PROFIBUS DP Masters, and AS-i (the 3 left-side communication

modules) and PROFINET are separate communications networks that do not limit each

other.

AS-i

The S7-1200 CM 1243-2 AS-i Master allows the attachment of an AS-i network to an S7-

1200 CPU.

CPU-to-CPU S7 communication

You can create a communication connection to a partner station and use the GET and PUT

instructions to communicate with S7 CPUs.

Teleservice communication

In TeleService via GPRS, an engineering station on which STEP 7 is installed communicates

via the GSM network and the Internet with a SIMATIC S7-1200 station with a CP 1242-7.

The connection runs via a telecontrol server that serves as an intermediary and is connected

to the Internet.

IO-Link

The S7-1200 SM 1278 4xIO-Link Master enables IO-Link devices to connect to an S7 1200

CPU.
