On the high-speed output module (Type_ NP1Y32T09P1-A), the ONL/ERR lamps are illuminated. Why does this happen?
Possible causes include a fuse blowout in the high-speed output module (Type_ NP1Y32T09P1-A).

When the power of P/PE-link is cycled, 0 data is transmitted, which I want to mask with an application. Are the configuration flag and the broadcas...
No, they are not synchronized. The configuration flag cannot be used for that application.
Use the broadcast area for handshaking using the application to ...

The area is cleared when the power supply is turned off once and turned on again.
The P/PE link memory is located in the built-in memory (RAM) of the P/PE-l...

In a redundant system, are the previous values retained for the SX bus and T-link outputs when the CPU is switched?
The input/output data continue to be valid after the CPU is switched. (The previous values are retained.)

When the communication cable is disconnected with an FL-net module (Type_ NP1L-FL1/FL2/FL3), are the FL-net common memory data retained? Or are the...
They are retained.
Note, however, that they are cleared if the power of the FL-net module is turned off.

Is it possible to have redundant (duplicate) Ethernet communication via the Ethernet interface module (Type_ NP1L-ET1/ET2) in a redundant system of...
The redundant function of the SPH Series provides redundancy only for the CPU and it cannot make the Ethernet redundant.

I understand that when data are received via an Ethernet network in the TCP/IP unpassive mode, requests from multiple nodes can be accepted. How ca...
Input an arbitrary address. This setting is ignored for the unpassive mode.

Is it possible to count differential input pulses using a high-speed digital input module (Type_ NP1X3206-A)?
Only open-collector (single-ended) signals are accepted. (NP1F-HC2 accepts differential signals.)
The rated current is 40 mA and an encoder that permits t...

In a redundant system, what will happen to the P-link memory at the time of switchover to a standby CPU?
The P-link memory is prepared in the P-link module. It is separate from the memory in the CPU and no change takes place at the time of switchover to a standb...
