Mold Pressure Module 5
Publication 1746-5.13 July 1998
3. Module I/O
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,
see the M0/M1 File Listing in section 11.
