7.4 Replacing older modules: Module replacement / upgrading
Distinction
When replacing existing modules with the module described here, the following variants
must be distinguished:
● Replacing a device
Describes the situation when an existing module can be replaced with a new module
simply by pulling/plugging without changing the configuration.
Note the information in section Installing and connecting up (Page 56) on plugging and
pulling the module. This applies in particular if you operate the CP as a PROFINET IO
controller.
● Upgrading (module replacement with compatible functions)
Describes the situation when the module described here can be used instead of an older
module as long as adaptations are made to the configuration. Here, the previously used
CP needs to be replaced in the configuration by the new CP.
Unless otherwise specified, the range of functions of the older module continues to be
supported.
You can also upgrade modules listed in "Module replacement". This is necessary when new
characteristics that were not available in the previously used module are required.
Note
The modules CP 443-1 EX30 and CP 443-1 Advanced GX30 cannot be used as spares to
replace each other (see below). You can, however, upgrade the EX30 with a GX30 if you
change the configuration.
Replacing a device
The CP with firmware-Version V3.2 described here can be used as a replacement for the
following predecessor products:
● CP 443-1 Advanced 6GK7 443-1GX20-0XE0
● CP 443 1 Advanced (6GK7 443-1EX41-0XE0) with CPUs as of firmware version 4.1
● CP 443-1 IT (6GK7 443-1GX11-0XE0) with CPUs as of firmware version 4.1
CPUs with firmware version 4.0 must be upgraded to 4.1.
When replacing modules with CPUs with a firmware version lower than V4.0, the
6GK7 443-1GX11-0XE0 or 6GK7 443-1EX41-0XE0 must continue to be ordered.
Note the other information in this section relating to the predecessor modules listed here.
Upgrading
The following predecessor products can be upgraded to the CP 443-1 Advanced
(6GK7 443-1GX30-0XE0) described here.
● CP 443-1 (6GK7 443-1EX20-0XE0)
● CP 443-1 Advanced (6GK7 443-1EX40-0XE0)
