5.3.3 Input Signals (PLC-IN)
The Input Signals are provided on the PLC IN connector. Inputs are assigned in the order as
shown in the table below and cannot be changed. Pins designated as “Not Used” have no
input assigned to them.
NOTE: When using Discrete I/O, “Bypass Press” input signals assigned to the PLC IN
connector can only be used for up to 10 individual presses (from the Main Unit). When using
Discrete I/O and you desire to connect this signal from additional presses, the signal must be
wired from the individual SAN Controllers using the SAN Unit’s PLC connector. An alternative
to this is to use a fieldbus interface which has control of all press bypass signals from the
interface.
Pin# Signal Contact Description
1 Emergency Stop N.C.
Emergency Stop Input.
Signal MUST be active to perform a pressing operation.
When this signal is inactive (off), all Main Unit operation
ceases, all presses in motion will stop and all communication
ports & input/outputs will be disabled.
2 Reset N.O.
Reset Input.
When active (on), this signal will clear all press data and
discrete outputs. A Zero Check of all load transducers will be
completed. During the Zero Check, the CHECK lamp will
illuminate, the READY signal will turn OFF, and the ACCEPT
or REJECT lamp will light to indicate the result of the Zero
Check. If the System has been disabled by an Abnormal
output, the System will not return to normal operation until the
Abnormal condition has been corrected, and this signal has
been input for 200~500ms. Do not input this signal between
cycles as part of an automatic cycle due to the potential for
press data loss.
3 Return N.O.
Return Input.
When used in conjunction with the Jog Input, the selected
press will move in the return direction for as long as this signal
is activated (on) and maintained.
4 Start N.O.
Start Cycle Input.
The Start input automatically resets the previous cycle, clears
all data to zero, and initiates the next pressing cycle. The start
input must be maintained "on" for the entire cycle (until the
“Busy” signal turns off).
When used in conjunction with the Jog Input, the selected
press will move in the advance direction for as long as this
signal is activated (on) and maintained.
5 Home N.O.
Home Input.
If a Home Position has not been set, a Home Position Search
will be initiated. When a Home Position (Origin) has been
established this input will move all connected presses to the
returned (Job Start) position. The Home input functions the
same as the Home pushbutton on the front of the Main Unit.
6 Jog (Manual Mode) N.O. Jog+Start advances the press. Jog+Return returns the press.
7 Seq. / Press Select 0 N.O. Sequence / Press Select Input.
These 5 inputs form a binary code which is capable of
selecting up to 32 different operation sequences. Refer to
Table 1.
When using manual operation inputs (Jog, Return), these
binary inputs are used to select the press to be operated.
8 Seq. / Press Select 1 N.O.
9 Seq. / Press Select 2 N.O.
10 Seq. / Press Select 3 N.O.
11 Seq. / Press Select 4 N.O.
12 Not Used N.O.
13 INPORT 1 N.O. External Sequence Input.
These four (4) signals are external inputs to the pressing
sequence. When a [PLC INPUT WAIT] instruction is
programmed in the pressing sequence, it will stop until the
designated external input is active.
14 INPORT 2 N.O.
15 INPORT 3 N.O.
16 INPORT 4 N.O.
17 BYPASS Press No.1 N.O. Bypass’s press #1 - Press is ignored as if it does not exist.
18 BYPASS Press No.2 N.O. Bypass’s press #2 - Press is ignored as if it does not exist.
19 BYPASS Press No.3 N.O. Bypass’s press #3 - Press is ignored as if it does not exist.
20 BYPASS Press No.4 N.O. Bypass’s press #4 - Press is ignored as if it does not exist.
21 BYPASS Press No.5 N.O. Bypass’s press #5 - Press is ignored as if it does not exist.
22 BYPASS Press No.6 N.O. Bypass’s press #6 - Press is ignored as if it does not exist.
23 BYPASS Press No.7 N.O. Bypass’s press #7 - Press is ignored as if it does not exist.
