8.3 IM151-1 STANDARD interface module
(6ES7 151-1AA04-0AB0)
Order number
6ES7 151-1AA04-0AB0
Properties
The IM151-1 STANDARD 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 STANDARD interface
module is also disconnected.
•
The maximum address space is 244 bytes for inputs, and 244 bytes for outputs.
•
The reference potential M of the rated supply voltage of the
IM151-1 STANDARD to the rail (protective conductor) is connected by means
of an RC combination, thus permitting an ungrounded configuration.
•
Operation as a DPV0 slave.
•
A maximum of 63 modules can be operated with the IM151-1 STANDARD.
•
The maximum bus length is 2 m (can be set).
•
Supports option handling (see Chapter 3.8) and the status byte for power
modules.
