Online Replacement of Unit Section 5 Maintenance
198 3BSE036351-510 A
Online Replacement of Unit
Replacement online entails adding or removing units in a controller without
disturbing the execution of the running application program. Units are connected to
the CEX-Bus and the electrical ModuleBus (S800 I/O).
CEX-Bus
Communication interfaces (CI8xx) Can be removed or replaced online.
Restrictions apply, refer to the
installation section for each interface
and to Appendix A, Hardware Units.
Baseplates for CI8xx (TP8xx) Must not be replaced online.
ModuleBus
S800 I/O units Can be removed or replaced online.
Module Terminal Units (MTUs) Must not be replaced online
Redundant CPUs
Processor unit Can be removed or replaced online
(see the next following pages)
RCU Link Cables Can be removed or replaced online.
However, the following restriction
applies; you cannot replace the RCU
link cable online in a previous than 4.1
software version. For more
information, see the instructions given
in Exchanging a Defect RCU Link
Cables Online on page 202.
It is not allowed to manipulate CEX bus baseplates in a powered and running
system. Before changing or removing a baseplate, all CEX modules on that
segment must be removed.
Section 5 Maintenance Exchange of CPU in Redundant Configuration without BC810
3BSE036351-510 A 199
Exchange of CPU in Redundant Configuration without
BC810
Follow the steps below to exchange a halted processor unit:
1. Disconnect the Power Supply Socket from the processor unit.
2. Disconnect the RCU link cables and optical ModuleBus cable from the
processor unit to be exchanged.
3. If PM86x is used, use a blade screwdriver to release the two spring-loaded
captive screws on the processor unit cover, and then carefully remove the
processor unit. If PM891 is used, carefully remove the unit.
4. Fit the new processor unit (which already has the correct firmware installed)
and tighten the screws.
5. Reconnect the Power Supply Socket to the new processor unit.
6. Reconnect the optical ModuleBus and RCU Link Cable.
7. Press the INIT push button on the replaced processor unit.
For PM86x, only the CPU unit can be exchanged during operation, and not the
associated baseplate. Removing the baseplate jeopardizes the functioning of
CEX-bus interfaces, if any.
For PM891, the entire unit cannot be exchanged during operation, without
jeopardizing the functioning of CEX-bus interfaces, if any
Before replacing, the new CPU must be loaded with the correct firmware as in the
existing CPU.
You do not have to disconnect the RCU link cables completely in order to
exchange a halted processor unit. Disconnect only the backup CPU, thus keeping
the RCU link cables connected to the primary CPU (now running in a single
state). However, if you must replace the RCU link cables, see Exchanging a
Defect RCU Link Cables Online on page 202.
The F(ault) LED of the new processor unit is temporarily lit when the power
supply is connected. This is not an indication of fault.
Pressing the INIT button initiates the restart that is required to keep the new
processor unit in redundant mode.
Exchange of CPU in Redundant Configuration with BC810 Section 5 Maintenance
200 3BSE036351-510 A
8. Observe the startup procedure and make sure that Dual mode is reached, that is,
the Dual LED is lit on both processor units.
Exchange of CPU in Redundant Configuration with BC810
If the BC810 is powered from an external power source, the entire CPU, with
baseplate, can be replaced during operation.
Follow the steps below to exchange a halted processor unit
1. Disconnect the Power Supply Socket from the processor unit.
2. Disconnect the RCU Link Cable and optical ModuleBus cable from the
processor unit to be exchanged.
3. Disconnect the Control Network cables.
4. Rotate the locking device to the SLIDE position (2) on the unit baseplate,
see Figure 17 on page 69.
During synchronization, the new processor unit inherits the IP address from the
running processor unit.
Reuse of CPU modules replaced from redundant configurations within the
same control network, might cause control network problems due to the MAC
and IP address handling. See MAC and IP Address Handling in Redundant
Configuration on page 49. Such reuse should not be fulfilled unless both the
replaced module and the module previously acting together with it in redundant
configuration are known to be restored from the previous mutual address swap.
It is recommended to set up an IP-config session and use the “Restore factory
settings” option subsequently followed by reassignment of the IP address or
assignment of a new IP address.
