Voltage supply of the IM 650 interface modules
In order to ensure availability in redundant mode with 2 x IM 650, we recommend use of a
separate power supply module for each IM 650.
7.7 System modification during operation
Plant changes in runtime are possible with the IM 650 in redundant and in non-redundant
configurations.
Plant changes in a non-redundant system
A detailed description of this function and its parameter assignment in non-redundant systems
can be found in function manual "Plant changes in runtime using CiR (
http://
support.automation.siemens.com/WW/view/en/14044916)".
Plant changes in a redundant system
Information on the use of this function in redundant configurations can be found in manual
"CPU 410-5H Process Automation (http://support.automation.siemens.com/WW/view/en/
74736834)".
7.8 Identification and maintenance data (I&M data)
Definition and properties
The identification and maintenance data (I&M) stored in a module supports you when:
● Checking the system configuration
● Locating hardware changes in a system
● Troubleshooting in a system
Identification and maintenance data (I&M) is supported by the IM 650 interface module as well
as by a few special I/O modules from the S7-300 series of modules.
Identification data (I-data) contains information about the module, such as article number and
serial number, some of which are printed onto the module housing as well. I-data is
manufacturer information about the module and can only be read.
Maintenance data (M data) is system-dependent information, such as installation location and
date. M data is created during the configuration and written to the module.
The modules can be uniquely identified online by means of the I&M data.
