Replacement of a Defective Module
Modules need to be replaced in the system when a defect occurs. The in-built replacement procedure
can be used to avoid re-programming for the new module. Devices of the same type can be replaced.
As a result of this procedure, the whole programming of the defective device is transferred onto the new
one.
The sequence of operations is as follows:
1. Disable the defective module in the network temporarily. The command to disable it is given at the
8.0.x.x.3. Disable
address, where x.x. is the shortcut address of the defective module.
2. Dismantle the defective module.
3. Install the new module at the same place.
4. Run the PnP procedure from the
8.1 Add hardware
address.
5. After the procedure is over, the new module should have been added at the end of the list of modules.
6. A replacement command is given for the new module from the
8.0.x.x.6 Replace
address, where x.x.
is the shortcut address of the new module. Here you have to enter the shortcut address of the defective
module.
Removal of a Module from the Network
If a module is to be removed from the system, the following sequence is applied:
1. Remove the module from the list of modules and the network, sending the command from the
8.0.x.x.5.
Remove
address, where x.x. is the shortcut address of the module.
Temporary Disabling of a Module in the Network
The following sequence of operations is applied if a module is to be disabled temporarily in the network:
1. Disable the module temporarily in the network by sending a disabling command from the
8.0.x.x.3.
Disable
address, where x.x. is the shortcut address of the module.
2. If necessary, the module can be enabled again and integrated into the normal operation of the system
with a command from the
8.0.x.x.4 Enable
address, where x.x. is the shortcut address of the module.
