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:

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.
