2.5 Requirements for use
2.5.1 Configuration limits
When using the CP type described here, the following limits apply:
● The number of CPs that can be operated in a rack depends on the CPU type being used.
By operating several CPs, you can increase the configuration limits listed below for the
station as the whole. The CPU does, however, have set limits for the entire configuration.
The size of the configuration made available by a CP can be increased by using more
than one CP within the framework of the system limits.
Observe the information in the documentation on the CPU; see section Guide to the
documentation (Page 9)
Note
Power supply via the CPU adequate or additional power supply modules required
You can operate a certain number of modules in the S7
-1500 station without an
additional power supply. Make sure that you keep to the specif
ied power feed to the
backplane bus for the particular CPU type. Depending on the configuration of the S7
-
1500 station you may need to provide additional power supply modules.
2.5.2 Project engineering
Configuration and downloading the configuration data
When the configuration data is downloaded to the CPU, the CP is supplied with the relevant
configuration. The configuration data can be downloaded to the CPU via a memory card or
any Ethernet/PROFINET interface of the S7-1500 station.
The following version of STEP 7 is required:
STEP 7 Professional V12 SP1 or higher The full functionality of the CP 1543-1
(6GK7 543-1AX00-0XE0) can be configured.
