5.3.4 Ouput Signals (PLC-OUT)
The Main Unit is capable of providing over 570 Output signals to indicate the status of the
Main Unit and of all the DSP1500 SAN Controllers connected to it (up to 31 controllers).
These signals are user configurable using the DSP User Console Software and may be
programmed on any designated pin. Up to 8 separate output data “Banks” can be set up,
each with 32 different output signals. The Output “Bank” is then selected using the Data
Select inputs (Data Select 0, Data Select 1, Data Select 2).
Available Main Unit Output Signals
Total Reject
Output when the pressing result is a REJECT. Indicates that one or more
presses have failed achieving the pressing limits. This output remains active
until the START signal or RESET signal is input.
Total Accept
Output when the pressing result is a ACCEPT. Indicates all presses are
within pressing limits. This output remains active until the START signal or
RESET signal is input.
Abnormal
Output when an Abnormal condition occurs. This signal indicates that the
System has detected an internal fault, and can no longer proceed. The fault
maybe generated from a connected press during a self-check function.
Check the individual press status to identify which press is reporting the
abnormal condition. (see DSP1500 Operation Manual for troubleshooting)
The press reporting an abnormal may be bypassed to resume normal
operation, however, the bypassed press will be ignored and not run while in
bypass. An Abnormal condition must be corrected before the System will
resume normal operation. The RESET signal clears the abnormal condition.
Ready
Output when the system is in the READY condition. Indicates system is
ready to operate, and inputs are enabled. This signal is inactive (off) when
the BUSY output is active (on).
Busy
Output after a START signal is received, and active until the pressing cycle
is complete and the READY signal is output.
End
Output when a pressing cycle is complete. Remains active until the START,
RESET or HOME signal is input.
Sequence / Press 0
Output confirmation of SEQUENCE / PRESS SELECT 0~4 input selections.
Sequence bits are active according to what sequence is set from the
sequence select inputs. Used to confirm proper sequence before pressing
starts. Refer to Table 2.
When in manual (Jog) operation the Press bits are active according to what
press is set from the press select inputs. Used to confirm proper press
selection before manual movement starts. Refer to Table 2.
Sequence / Press 1
Sequence / Press 2
Sequence / Press 3
Sequence / Press 4
Out Port 1
These signals will output when the pressing sequence reaches a step that
has a [PLC OUTPUT] instruction inserted. Used to provide sequence
operation status to external PLC’s and/or control outputs for slide motion,
lights, & buzzers, etc without the use of a PLC. (The DSP User Console
Software can set these outputs on and off in the pressing sequence)
Out Port 2
Out Port 3
Out Port 4
Out Port 5
Out Port 6
Out Port 7
Out Port 8
Press in Bypass
Signal is active when any of the connected Presses are bypassed either
from San Unit bypass input signals or from the San Unit bypass switch.
Always ON / OFF
Can be used to set outputs ON or OFF. Typically used in conjunction with
Bank Outputs to monitor which Bank is selected.
