When the machine tool builder creates a MDI keyboard which has no
cursor keys on the PMC–MODEL SA1/SA3 of the FS 20, note the
following methods of operation. Ladder diagrams cannot be edited using
the ladder–diagram–edit memory card.
On each setting screen, when an item is specified, the cursor automatically
moves to the next item to be specified. When the item at the cursor need
not be modified, specify the same value again. When the item at the
bottom of the screen has been specified, the cursor automatically moves
to the item at the top of the screen (CHANNEL setting). When the return
key (leftmost soft key) is pressed to exit from the I/O screen, the cursor
automatically moves to the top of the screen. Examples of setting items
are shown below.
Example 1) When a ladder program is output to an off–line programmer
(such as the P–G or a personal computer)
1 CHANNEL setting : Enter the desired channel number,
then press the <INPUT> key or
[(NO.)] key. To use the current value,
just press the <INPUT> key or
[(NO.)] key.
2 DEVICE setting : Press the [HOST] key. The cursor
returns to the CHANNEL setting
position to enable CHANNEL
setting.
Example 2) When a ladder program is written into an F–ROM
1 CHANNEL setting : No specification required. To move
the cursor, perform the operation
described in 1 of Example 1.
2 DEVICE setting : Press the [F–ROM] key.
3 FUNCTION setting : No specification required. To change
the CHANNEL setting, press the
[WRITE] key to return the cursor to
the CHANNEL setting position.
Example 3) When a ladder program or a PMC parameter is read from or
written into an FDCAS (M–CARD)
1 CHANNEL setting : See 1 of Example 1 (or 1 of Example
2).
2 DEVICE setting : Press the [FDCAS] ([M–CARD]) key.
3 DATA KIND setting: Press the [LADDER] key for ladder
operation. Press the [PARAM] key
for PMC–parameter operation.
4 FUNCTION setting : Press the [READ]/[WRITE] key.
5 FILE NO. setting : Enter the desired file number or file
name, then press the <INPUT> key or
[EXEC] key. When the current value
is used, just press the <INPUT> key.
The cursor automatically returns to
the CHANNEL setting position. The
setting can be modified.
In each example, pressing the [EXEC] key after setting data executes the
corresponding processing.
