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.
• Operation as a DPV0 slave.
• A maximum of 12 modules can be operated with the IM151 1 BASIC.
• The maximum bus length is not relevant.
