When there are multiple supplying mats of materials, the indicator has to control
these gates. There are the following two method to control them.
Case 1: Direct Gate Control
The method that connects the gate control lines of supplying hoppers to the I/O
terminals of the indicator and the indicator directly controls them.
Three kinds of gates can be used in a supplying hopper. (Full, medium, dribble gate)
Number of supplying hopper:
Preset material codes and recipe codes can be used.
The selection of the supplying hopper is [MatEDIT] - [Material code] - [Material hopper].
The selection of the I/O terminals is [Function] - [Function setting] - [Control I/O Function] - [Output].
Even if a code is recalled during the sequence, the code does not work until the
sequence finishes.
When the number of I/O terminals is not enough, use relay output option (OP-02) and
parallel I/O (OP-05).
Case 2: Gate Control with Supplying Hopper Selection
The method:
Make gate-lines that gates of a kind, in each supplying hopper are connected to
the I/O terminal of the indicator in parallel.
Make hop-lines that lines identified by each hopper are connected to the I/O
terminal.
The indicator can control any gate which the gate-line and hop-line are active.
(logical AND gate)
Three kinds of gates can be used in a supplying hopper. (Full, medium, dribble gate)
Number of supplying hopper:
Preset material codes and recipe codes can be used.
The selection of the supplying hopper is [MatEDIT] - [Material code] - [Material hopper].
The selection of the I/O terminals is [Function] - [Function setting] - [Control I/O function] - [Output].
When number of I/O terminals is not enough, use relay output options (OP-02) and
parallel I/O (OP-05).
Ten hoppers can be used.
Twenty hoppers can be used.
