The ET 200pro EtherNet/IP module
3.4 Faults
Module hot swap
The ET 200pro distributed I/O system supports removing and inserting one electronic
module (one gap) while the device is active on the network without removing power.
The ET 200pro remains in RUN state when the electronic module is removed.
The ET 200pro station fails if you remove more than one electronic module.
Hot-swapping electronic modules in RUN state is supported only if the "Operation in setpoint
<> actual configuration" parameter is enabled for the ET 200pro EtherNet/IP module.
To perform the hot-swap, you will need a size 2 cross-tip (or Phillips) screwdriver and
pointed pliers.
To replace an electronic module, follow these steps:
1. Using the screwdriver, remove the two screws from the front of the connection module
from the right side top and bottom.
2. Remove the connection module next to the electronic module from the bus module.
3. While pressing the interlock button on the top of the electronic module, pull the
connection module upwards and out of the electronic module.
4. Remove one half of the coding key from the new electronic module (top left).
5. Insert the connection module into the electronic module (same type).
6. Insert the connection module with the electronic module into the bus module and screw it
down.
To change from one type of electronic module to another, follow these steps:
1. Using the screwdriver, remove the two screws from the front of the connection module
from the right side top and bottom.
2. Remove the connection module next to the electronic module from the bus module.
3. While pressing the interlock button on the top of the electronic module, pull the
connection module upwards and out of the electronic module.
4. Use the pointed pliers to remove one half of the coding key from the connection module
(top right).
5. Insert the appropriate connection module into the replacement electronic module.
6. Insert the connection module with the electronic module into the bus module and screw it
down.
7. Change the configuration using the EIP ET200 Configuration Tool and download it to the
EtherNet/IP master device.
Changing the coding
If you change the coding, this may result in a mismatch between the ET 200pro EtherNet/IP
module and the connection module, which could result in dangerous plant conditions.
