Installation and commissioning
5.3 Commissioning - procedure
CP 443-1 (EX30)
42 Manual, 03/2019, C79000-G8976-C255-05
Commissioning - procedure
The steps for commissioning the CP are explained below. Commissioning involves the
addressing and downloading the configuration data and user programs.
Result: The CP is reachable in the network and has been supplied with configuration data.
Follow the steps outlined below:
1. Download the configuration data from your STEP 7 project to the S7400 station.
– Requirement:
You have configured the CP in a STEP 7 project for the properties and services you
want to use.
Note
You can connect the PG when configuring the CP as follows:
via MPI
via Industrial Ethernet
For further details, refer to the general part /2/ (Page 82) of this manual:
– Initial addressing (node initialization);
– Downloading the configuration
The PG/PC requires a LAN attachment, for example via a CP 1613 or CP 1411 and
must have the necessary software (for example the S7
1613 package or SOFTNET
IE). The TCP/IP protocol or ISO protocol must be installed. The protocol used must
then be applied to
the S7ONLINE access point.
2. Use the diagnostics functions during commissioning and to analyze problems.
You have the following options available:
– Hardware diagnostics and troubleshooting with STEP 7.
– Communication diagnostics with special diagnostics.
– Web diagnostics.
Note
Module replacement - adapting the cycle load with an older CPU
If you use the CP as a replacement with an older CPU, the default communication
load setting of 20% for the CPU can lead to overload. In this case, you should set the
communication load for the CPU in STEP
7 (parameter "Scan cycle load from
to a lower value - for example 10%.
With CPUs as of version V5.1, changing the setting is unnecessary.
