Trouble shooting network problems with ACS Mitsubishi blenders or
Maguire WSB blenders
Problem
You’ve configured more than one Ethernet device and none of them are
communicating. Pictures shown may differ with Maguire Digi One SP
module, but the descriptions of LEDs and DIP switches are the same
Solution
It is easy to trouble shoot when you have some devices communicating (at
least one), but with none communicating you’re going to have to start from
the beginning.
Step1: Disconnect all of the blenders except for one. Get this one working
and then go to the next one.
Step2: Examine the Dipswitch settings on each of the DIGI Ethernet
modules. Switch 1 should be on and 2-4 off (see below).
Step 3: Examine the “Power” light on the PLC’s Ethernet module. If it is not
on then check the 24VDC power connection to the module.
