SIMATIC S7-400
Central processing units
PROFIBUS module IF-964 DP
■ Overview
• For connecting distribute d I/Os using PROFIBUS DP
• Transmission rate max. 12 Mbps
• Electrically isolated RS 485 interface
• Connection by means of 9-pin Sub D socket
• One or two PROFIBUS module s can be plugged into each
S7-400 CPU:
- CPU 414-3/416-3: 1 module
- CPU 417-4: 2 modules

■ Technical specifications
Current consumption
• from CPU, max.
• Power dissipation, typical
6ES7 964-2AA04-0AB0
150 mA; Current consumption
from S7-400 bus: the module
does not take up current at 24 V,
it merely makes this voltage
available at the DP interface.
Total current consumption of
the components connected to the
DP interface, to a maximum of
150 mA.
