Configuration of the CP
● New ST7 systems, DNP3 systems, IEC systems
To configure the CP in new systems with one of the telecontrol protocols named above
use STEP 7 Basic.
In these systems use a CP with firmware version V3.
● Existing ST7 systems
In existing SINAUT systems with SIMATIC stations of the families S7-300/400 and the
TIM modules for remote transfer, the CP can be used for expansions by S7-1200
stations.
In these systems that were configured with STEP 7 V5, use a CP with firmware version
V2.1.
To configure the CP, you require the two following STEP 7 products:
– STEP 7 V5
and
– STEP 7 Basic
For information on the required STEP 7 versions, see section Requirements for operation
