Reset I/O to defaults op code (02) does not perform all documented operations


Applies To:

Firmware for:

  • GRV-EPIC-PR1
  • GRV-R7-MM1001-10

Versions Affected:

Resolved In Version:

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

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

groov RIO

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

Workaround:

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

Resolution:

Opto 22 has resolved this issue.
