2.5 Operation Panel I/O Unit
Characteristics of operation panel I/O unit are as follows.
(1) Number of DI/DO points that can be mounted on the machine operation panel is 64/64 at the minimum and 96/96 at
the maximum.
Operation panel I/O unit DI/DO uses equivalent serial link connections as those used for remote I/O.
(2) Remote I/O interface --- 1ch
Extension with remote I/O unit is possible up to 4 stations.
(a) When FCU7-DX711 is used: Up to 4 stations, 128 points/128 points in total, are available.
(b) When any one of FCU7-DX621/721/731 is used: Up to 3 stations, 96 points/96 points in total, are available.
(Note) The maximum number of stations that can be extended is described above whether DI/DO of the
operation panel I/O unit is used or not.
(3) Manual pulse generator --- 2ch
5V and 12V manual pulse generators can be connected.
(4) Installation on the back side of the keyboard unit is possible. Allows space saving inside the operation panel.
(Note 1) The station Nos. occupied by the operation panel I/O unit cannot be changed.
(Note 2) Set the number of DI points that are simultaneously turned ON to be less than half of the total points. If many
points are set to be simultaneously turned ON in high temperature, operation panel I/O unit may be
deteriorated due to the heat.
