8.2 IM151-1 BASIC Interface Module (6ES7 151-1CA00-0AB0)
Order Number
6ES7 151-1CA00-0AB0
Features
The IM151-1 BASIC interface module has the following features:
It connects the ET 200S with PROFIBUS-DP via the RS485 interface.
It prepares the data for the electronic modules and motor starters that are fitted.
It supplies the backplane bus.
The PROFIBUS-DP address of the ET 200S can be set by means of switches.
If the 24 VDC power supply is disconnected, the IM151-1 BASIC interface
module is also disconnected.
The maximum address space is 88 bytes for inputs and 88 bytes for outputs.
The reference potential M of the rated supply voltage of the IM151-1 BASIC to
the rail (protective conductor) is connected by means of an RC combination,
thus permitting an ungrounded configuration.
It can be operated as a DPV0 slave.
A maximum of 12 modules can be operated with the IM151-1 BASIC.
The maximum width of the station is not relevant.
Terminal Assignment
The following table shows the terminal assignment of the IM151-1 BASIC interface
