1.2 Functions
The Main Unit is a complimentary controller device to enhance the DSP1500 capabilities by
providing the communication and the sequence control features required by larger or more
sophisticated multi press applications. When a group of DSP1500 Servo Controllers (SAN Units) are
linked to a Main Unit, the Main Unit assumes control (over these presses) of the following functions:
ƒ Input-Output (I/O) Connection (including Fieldbus interface)
ƒ Sequence Control
ƒ Parameter Programming
ƒ Pressing Data Monitoring & Communication
ƒ General Status Indication
♦
Input-Output Connection (including Fieldbus interface)
The Main Unit assumes control of the control signals (Ex.: STOP, START, RETURN,
BYPASS, etc.) to all of the DSP1500 Servo Controllers linked to it via the RS485
communication port, thus eliminating direct connection & control to the individual presses.
The control signals for the multi-press array can be of different sources: Signals manually
generated by pressing the Control Buttons on the front of the Main Unit or I/O (Input/Output)
signals from a PLC or from a PC Based Controller.
♦ Sequence Control
The Main Unit controls the pressing sequencing eliminating the need for external control
devices (PLC) to perform complicated control sequencing. All pressing sequencing is
handled by the Main Unit. This built in feature allows the Main Unit to control a variety of
complex sequencing strategies including; several pressing steps, reject (retry) strategies,
wait timing, multiple starts, etc.
♦
Parameter Programming
A Windows® compatible computer running the DSP User Console software package can be
connected to the Main Unit in order to upload or download the preset data to all the SAN
(Servo) Controllers connected in the multi press array. This eliminates the need to program
individual presses manually.
♦
Pressing Data Monitoring & Communication
The Main Unit can monitor and process the pressing results collected by the DSP1500 Servo
(SAN) Controllers connected to it. It has four (4) configurable RS232C ports to input and
output pressing data results. Data monitoring / saving is also a function of the DSP User
Console software package.
As an added feature, the Main Unit stores previous pressing data in RAM (volatile) for
uploading at another time. The number of cycles stored is based on the number of presses
connected (see chart on page 2-2). The data can be uploaded using the DSP User Console
software package.
♦ General Status Indication
A set of indicator LED’s provide the status for Power On, Busy, Total Accept, Total Reject and
Abnormal conditions.
