I/O module replacement
during operation
If an I/O module becomes abnormal during operation, the module
can be replaced with a new one during the system operation. The
procedure is as follows:
© Connect the programmer to the CPU module,
d) From the programmer, specify the module for removal. (The
module is disconnected from the T3 operation.)
(D Remove the failed module.
0 Insert a new module.
CD By using the programmer, cancel the function for removal.
This function can be applied to the following failures of discrete I/O
modules.
•
An input module does not read the specific signal (failure of the
input photo-coupier, etc.).
•
An output module does not output a specific signal (failure of the
output device, etc.).
•
The fuse of an output module has blown out.
CAUTION (1) Except when using this function, turn OFF power
before replacing a module. Exercise caution when
this function is used for safety.
(2) Effective I/O modules for this function are the discrete
I/O modules.
(See separate T3 User's Manual-Fanctions, for
details.)
(3) Refer to 4.3 Mounting modules, for replacing I/O
modules.
