Inputs

The module has two independent channels that you configure to process

signals from machine sensors (default) or from the SLC output image table

across the backplane. Types of machine sensors include::

Outputs (Summary Data)

The module processes a frame of summary data for each molding cycle,

and alternately makes available the previous frame for display. It does this

for channels 1 and 2. Your ladder logic can read summary data from the

module’s M0/M1 files. You can observe summary data displayed on a PC

equipped with DARTWin software. The PC must be linked to the module

with DARTNet network from RJG Technologies, Inc.
A list of summary data follows. For a complete list with word addresses,
