Replacing the interface module
Note
Switching the bus termination resistor
When switching the bus terminating resistor, the PROFIBUS DP line remains interconnected.
1. Note the setting of the bus terminating resistor on the IM to be replaced.
2. Ensure that the bus terminating resistor is set to "ON" at exactly one of the adjacent IMs.
3. Ensure that the bus terminating resistor on the IM to be replaced is set to "OFF".
4. Pull out the bus plug from the IM to be replaced.
5. Pull the (defective) IM 152 out of the terminal module.
6. Set PROFIBUS DP address "0" on the new IM 152 and plug it into the terminal module.
7. Switch the supply voltage of the ET 200iSP off and on.
8. Wait until the retentive data of the interface module has been erased (BF LED flashes with
0.5 Hz).
9. Switch on the supply voltage of the ET 200iSP.
10.Now set the PROFIBUS DP address of the (defective) old IM 152 on the new interface
module.
11.Switch the supply voltage of the ET 200iSP on again.
12.Wait until the replaced IM has started.
13.Connect the bus plug to the replaced IM.
14.Ensure that the bus terminating resistor is set to the setting noted in the first step.
15.Parameter assignment of the ET 200iSP with STEP 7:
– The ET 200iSP is automatically re-configured by the controller and then switches to data
communication with the DP master.
If you need the I&M data, you also need to load it into the ET 200iSP (menu command
HW Config PLC > Download Module Identification).
– If you use SIMATIC PDM, you need to load all parameters and I&M into the ET 200iSP
(menu command Device > Download Entire Program to Device).

Maintenance during operation
Properties
Maintenance of the ET 200iSP is effectively restricted to visual inspections. These can be
performed while the ET 200iSP is operating.
Prerequisites
In hazardous locations, a visual inspection should be made every six months.
