Commissioning The Im 151-7 Cpu As A Dp Master - Siemens SIMATIC ET 200S Manual

6.2

Commissioning the IM 151-7 CPU as a DP master

Prerequisites for commissioning
S The PROFIBUS subnet has been configured.
S The DP slaves have been prepared for operation (see the relevant DP slave
manual).
S The IM 151-7 CPU must be configured as a DP master prior to commissioning.
This means that you must use STEP 7
S
to
– configure the IM 151-7 CPU as a DP master (DP master interface),
Note
In the HW configuration, you must hang the DP master module in the station
window separately as a submodule (X2).
– assign the IM 151-7 CPU a PROFIBUS address,
– assign the IM 151-7 CPU a master diagnosis address,
– integrate DP slaves in the DP master system.
Is an IM 151-7 CPU a DP slave?
If so, you will find this DP slave in the PROFIBUS-DP catalog as a
pre-configured station. In the DP master, you assign a slave diagnosis
address to this DP slave CPU. You have to couple the DP master with the
DP slave CPU and define the address ranges for the data exchange with the
DP slave CPU.
Commissioning
Commission the IM 151-7 CPU as a DP master in the PROFIBUS subnet as
follows:
1. The DP master module is mounted as described in Chap. 6.1.
2. Switch the supply voltage on.
3. Load the configuration of the PROFIBUS subnet (preset configuration) created
with STEP 7 into the IM 151-7 CPU with the PD.
4. Switch all DP slaves on.
5. Switch the IM 151-7 CPU from STOP to RUN.
