Troubleshooting 21
6000 Series Controller/Indexer
First, verify that 6000 Series Controller/Indexer I/O is functioning properly
to aid in isolating the problem. Disconnect the 50-pin ribbon cable, or just
disconnect the cable from connector J4 of the VM24, before performing this
test.

Outputs:

Use the Transfer Output Status (TOUT) command to check the status
of the outputs. Use the Output State (OUT) command to change the
outputs. Use a voltage meter to check individual outputs at the I/O
connector of the 6000 Series unit to verify that the voltage level
toggles between Ground and Vo.

Inputs:

Use the Transfer Input Status (TIN) command to check the status of
the inputs. Use the Input Active Level (INLVL) command to define
the active state of all programmable inputs. Alternate between
applying supply voltage Vi to an input and grounding it, using the
TIN command to verify that the input toggles as you do so.
If the inputs or outputs do not appear to be functioning properly at
the 6000 Controller level, refer to the Common Problems &
Solutions section of the Troubleshooting chapter in the User Guide
or Installation Guide for the 6000 Series Controller/Indexer being
used in the application. Specific I/O problems are addressed in the
table.
Note: For additional information on 6000 Series commands,
refer to the 6000 Series Software Reference.
