Hot swap behavior
Hot swap behavior
Central I/O on V3 CPU
Start-up behavior with unplugged or damaged
I/O module on hot swap terminal unit TU5xx-H
System and I/O modules attached to the CPU
are starting (except unplugged or damaged
module when plugged on hot swap terminal
unit).
As soon as the correct and operational I/O
module is plugged on the terminal unit, the
module is configured and ready to start.
No specific setting needed.
Start-up behavior with wrong I/O module type
on any terminal unit
System and I/O modules are not starting
Diagnosis of presence of hot swap terminal
unit
Diagnosis using PLC browser command "io-
bus desc" in Automation Builder V3.
The PLC browser then provides an overview
of the modules on the I/O bus including the
position of hot swap terminal units in the
I/O bus.
In the application program this
can be detected with a func-
tion block "IoModuleHotSwapInfo"
(Library: AC500_Io/Function Blocks/I/O-Bus).
One instance of function block is needed per
terminal unit on the I/O bus. The function
block provides five outputs delivering infor-
mation about slut number, hot swap capa-
bility and plugged/unplugged state of the I/O
module
Diagnosis while hot swap module is pulled or
module (mounted on hot swap terminal unit)
has stopped working
If module is pulled then diagnosis Err 9480
"Module removed from Hot Swap Terminal
Unit" is generated
Diagnosis after plugging the I/O module on
the hot swap terminal unit
Diagnosis Err 9480 is automatically
acknowledged
Maintenance
