Maintenance and service
7.4 Replacing the IM 153-2 or IM 153-2 FO
ET 200M
Operating Instructions, 12/2008, EWA-4NEB780600602-08
105
Installing a New Module
Install the new module as follows:
1.
On the IM 153-1 set the same DP address as you had on the old IM 153-1.
2.
Insert the new IM 153-1 and swing it down.
3.
Screw the module on securely.
4.
Wire the IM 153-1.
5.
Screw the bus connector firmly into place.
6.
Put the standby switch of the power supply module into the 1 position (output voltages to
rated value).
Response of the ET 200M After Module Replacement
If there is a fault after replacing the module, with
STEP 5 or STEP 7 in the diagnostics buffer
you can view the cause of error.
7.4
Replacing the IM 153-2 or IM 153-2 FO
Initial Situation
The IM 153-2 / -2 FO is installed. A new IM 153 -2 / -2 FO of the same type should be
installed.
Slot numbering
If you have provided the modules in your system with slot numbering, when replacing
modules you must remove the numbering from the old module and then reuse it in the new
module.
IM 153-2: Pull out the bus connector
You can remove the bus connector with worn-through bus cable from the PROFIBUS DP
interface without having to interrupt the data traffic to the bus.
Note
A data communication error may occur on the network.
On both ends, the bus segment must always be connected to the terminating resistor. For
example, this is not the case when the last slave with the bus connector is deactivated. As
the terminating resistor in the bus connector obtains its voltage from the node, the function of
the terminating resistor is affected.
Ensure that the nodes to which the terminating resistor is connected are always supplied
with voltage.
Tip: Use the PROFIBUS terminator as an active bus connector.
