Applies To:

Firmware for:

Resolved In Version:

GRV-EPIC-PR1: 3.2.1

Symptoms:

In the groov Manage Generic MMP page, when you write the Reset I/O to Defaults OpCode (02) to the Status Write Area (0xFFFF F038 0000) of the memory map, it does not perform all documented options:

Discrete output channels are not turned off
Currently running TPOs are not turned off

Note: The GRV-EPIC-PR1 presented a similar issue with the Reset I/O to Defaults feature in groov Manage (see KB88247).

To get to the Generic MMP page:

groov EPIC

From groov Manage Home, click I/O.
Click I/O Tools.
Click Generic MMP.

groov RIO

From groov Manage Home, click I/O Tools.
Click Generic MMP.

Workaround:

Turn off all digital outputs (which also cancels TPO).

Resolution:

Opto 22 has resolved this issue.
