4.2 Cyclic Transmission
I/O maintenance settings
When using cyclic transmission, set whether to hold or clear output on the sending side or input on the receiving side by using
the following settings of (A), (B), and (C). ( Page 138 Supplementary Cyclic Settings)
• Setting on sending side (A): "Output Mode upon CPU Error" when a stop error occurred in the FX5 CPU module on the
sending side
• Setting on sending side (B): "Output Hold/Clear Setting during CPU STOP" when the status of the FX5 CPU module on the
sending side changed from RUN to STOP
• Setting on receiving side (C): "Data Link Faulty Station Setting" when the sending side is disconnected

Input data hold/clear operation on the receiving side
If an FX5 CPU module stop error occurred on the sending side
• If both settings (A) and (B) on the sending side are "Hold", input data on the receiving side is held.
• If setting (A) or (B) on the sending side is "Clear", input data on the receiving side is cleared. (The sending side sends the
data cleared to 0.)
If the FX5 CPU module on the sending side changed from RUN to STOP
• If setting (B) on the sending side is "Hold", input data on the receiving side is held.
• If setting (B) on the sending side is "Clear", input data on the receiving side is cleared. (The sending side sends the data
cleared to 0.)
If the sending side disconnected
• If setting (C) on the receiving side is "Hold", input data before disconnection is held on the receiving side.
• If setting (C) on the receiving side is "Clear", input data on the receiving side is cleared.
Precautions
When "Output Hold/Clear Setting during CPU STOP" is set to "Clear"
When the FX5 CPU module is in the STOP state, the forced output to device stations cannot be executed using the
engineering tool.
