Maximum Configuration Of The Et 200Isp - Siemens SIMATIC ET 200iSP Operating Instructions Manual

Configurations (principle)

4.7 Maximum configuration of the ET 200iSP

Note
If you replace the IM 152-1DP with IM 152-1PN, note the higher functional current consumption
of the IM 152-1PN.
Fail-safe modules have a higher functional current consumption than standard modules. See "ET
200iSP Distributed I/O Device - Fail-safe Modules
support.industry.siemens.com/cs/us/en/view/47357221)".
Calculating the ET 200iSP power loss
You can calculate the power loss of the ET 200iSP using the following formula:
P
Vtotal
Explanation:
x*5W = basic power loss of power supply (x = 1 for standard configuration, x = 2 for redundant
configuration)
1.2*∑
power supply.

Number of the ET 200iSP stations
• Connection via PROFINET IO
The number of ET 200iSP stations on an IO controller is limited by the quantity structure of
the IO controller.
• Connection via PROFIBUS
The number of ET 200iSP stations on DP masters is limited:
For S1 and S2 configuration with an IM 152-1DP: Maximum of 31 ET 200iSP stations per
segment of the PROFIBUS RS 485-IS (connection via the RS 485-IS coupler required)
For R1 configuration with IM 152-1DP: Maximum of 32 ET 200iSP stations per segment of the
PROFIBUS RS 485-IS (connection via the RS 485-IS coupler required)
Current consumption of the ET 200iSP at maximum configuration
Information on the permissible current consumption can be found in the technical
specifications of the connected power supply:
• Power supply PS 24 VDC (Page 269)
• Power supply PS 120/230 VAC (Page 272)
