Select Command and Status Bits to Sequence
Machine Operation
In this chapter, we provide you with tables of command and status bits that
you use to write ladder logic to:
implement manual functions such as jog, set outputs, and stop
step your QDC module through machine cycles
We suggest how to assess your logic requirements and based on those
requirements how to use bit tables to write your machine’s sequential
ladder logic.
Important: You must write your own ladder logic for machine sequencing
because it depends on your machine’s hydraulic configuration and your
application. It is not included in Pro-Set 600 software.
Assess your logic requirements according to how your machine must be
sequenced.
If you need to Refer to this table for required
command and/or status bits
Execute phases of the inject, clamp,
and eject mode without interruption
no additional ladder logic required
Jog your machine in manual mode,
set outputs, or stop
6.A
Start the next profile or movement 6.B and 6.C
Interrupt movement between profiles 6.D
Trigger new events
6.E
Review all available status bits 6.F
Review all available command
and configuration bits 6.G
Important: For a more thorough description of all command and status
bits presented in this chapter, refer to Section 3 of the Plastic Molding
Module Reference Manual (publication 1771-6.5.88).
