Graphic Operation Terminal GOT-F900
Data change condition:Numeric and ASCII codes cannot be changed in the following cases.
1) GOT status
- While change is forbidden (During communication with FX-PCS-DU/WIN-E)
When the data change target object is set to "FORBID".
Countermeasures: Set the object to "PERMIT".
- When an input value is outside the range from the lower limit to the upper limit
The upper limit and lower limit are provided to indicate the allowable data setting range. If
the input value is outside this range, it is not accepted.
Countermeasures: Change the upper/lower limit value.
- When "****" is displayed on the screen
When a device No. not present in the PLC is monitored, the numeric data is displayed as
"****" on the screen.
Countermeasures: Change the device No. whose numeric data is to be monitored on the
screen.
For the countermeasures above, numeric setting should be changed in the screen
creation software.
2) PLC status
- When an EPROM memory is mounted in the FX/A Series PLC, set values of timers,
counters and current values of file registers cannot be changed.
- When an EEPROM memory is mounted in the FX Series PLC or while the FX/A Series
PLC is running, set values of timers, counters and current values of file registers cannot
be changed.
- When an entry code is registered in the FX/A Series PLC, set values of timers, counters
and current values of file registers cannot be changed. Reset the entry code.
n n n n Important point
Timing of data change for "Number" ("Numerical Input") and "Ascii" ("Ascii Input")
Data is changed in the PLC at the following times.
When new data is entered and the ENT key is pressed, the new data is transferred to the
PLC. When the CLR key is pressed before the ENT key, the new data is ignored and the
existing data is kept registered.
Layout of "Number" ("Numerical Input") and "Ascii" ("Ascii Input")
A touch key can occupy 12 (horizontal direction) × 20 (vertical direction) dots. When a touch
key occupies an area equivalent to or more than the half of 12 × 20 dots, it is recognized as
touch key.
When half- or full-width numerics and ASCII codes are laid out, a touch key may not be
recognized as touch key depending on its position. In such a case, change the layout, display
the touch key with a frame or display the touch key in a size whose vertical dimension is twice
or larger. (Refer to Paragraphs 10.5.1 and 12.5.1.)
