Control engine may reset when Node-RED/PAC REST API access table data

Knowledge Base - KB88929 - 5/5/2020

If a Node-RED flow or PAC REST API code reads a recipe stored in a table in a controller strategy while PAC Display (or other HMI) is downloading a recipe to that table, the controller may stop responding or reset.

S1 or S2 controller in a redundant system shows "non-qualified" when using persistent timer variables

Knowledge Base - KB88905 - 5/26/2020

In a redundant SNAP PAC controller system (using the SNAP-PAC-ROK), the PAC Redundancy Manager reports that the backup controller is "non-qualified" instead of "qualified." This issue occurs when using persistent timer variables.

SNAP PAC controller in a redundant system may reset when you try to view errors in the queue

Knowledge Base - KB88854 - 5/26/2020

A SNAP PAC controller in a redundant system may reset when you try to view errors in the queue. This issue applies only to a redundant system using S-series controllers and the SNAP-PAC-ROK.

Restore fails if Node-RED is disabled before power cycle

Knowledge Base - KB88907 - 5/5/2020

In groov Manage, if you disabled Node-RED (Home > Node-RED > Disable), then cycle power on your GRV-EPIC-PR1, and then try to restore a backup (Home > Maintenance > Restore), the restore will fail

groov EPIC module LED may be red and module may not show up in groov Manage

Knowledge Base - KB88865 - 5/5/2020

If the LEDs for 1 or 2 modules on a groov EPIC chassis are red or the modules do not appear in groov Manage, you may be running into this issue. This issue does not affect simple modules (discrete groov I/O modules that provide on/off status only).

On an external monitor, top half of screen appears on bottom half of monitor

Knowledge Base - KB88874 - 5/5/2020

On an external monitor, the top half of the screen (for example, the top half of a groov Manage page) appears on the bottom half of the monitor.
