Email notifications for triggered alarms inconsistently sent
Knowledge Base - KB90590 - Published:
If you have configured PAC Display to send emails when alarms are triggered, the delivery of those emails (especially subsequent emails for multiple triggered alarms) may be inconsistent and not coincide with when the alarms are triggered.
GRV-OVMALC-8: Configuring channel type to Analog Hi-Z not saved correctly
Knowledge Base - KB90664 - Published:
If you change the channel type of any channel on a GRV-OVMALC-8 module from any type to Analog Hi-Z, the configuration is not saved correctly. In groov Manage, the channel status page incorrectly...more
PAC Manager cannot confirm reboot of E1 or E2 brain boards when installing firmware
Knowledge Base - KB90678 - Published:
In PAC Manager, instead of seeing a “Success” message after installing firmware on an E1 or E2 brain board, you may see the status message: “Firmware update completed, but restart could not be confirmed.”
E2 analog inputs report a constant, invalid value
Knowledge Base - KB90700 - Published:
Channels 0-7, 8-15, or all channels stop measuring inputs and report 0 counts or 61440 counts (if configured to read counts) or an invalid engineering unit value (if configured to read engineering units)...more
Clear All Latches command may cause processor/controller reset
Knowledge Base - KB90702 - Published:
If your PAC Control strategy uses the Clear All Latches command on a SNAP I/O unit that has unconfigured points or empty module positions, the groov EPIC processor or SNAP PAC controller will reset.
I/O unit incorrectly reports communication enabled after power cycle
Knowledge Base - KB90689 - Published:
After an I/O unit cycles power and your PAC Control strategy tests if the I/O unit is available with the Is I/O Unit Ready? and ​I/O Unit Communication Enabled?, the I/O unit may incorrectly report communication as enabled.
Some channel configurations may not restore from persistent memory
Knowledge Base - KB90696 - Published:
If you configure channels on through groov Manage and then restart the groov RIO module or groov EPIC processor, one or more of the I/O channel configurations may not be restored from persistent memory.
MQTT string protocol fails to write floats to analog outputs, timers, and float variables
Knowledge Base - KB90648 - Published:
If you enable the “Use Comma for Decimal Separator” option when you configure the MQTT String protocol in Data Service, when the protocol writes floats to analog outputs, float variables, and timers, the writes will fail.
When MQTT Sparkplug sends out updates stored in historic queue, other protocols may slow down
Knowledge Base - KB90644 - Published:
In the event of an MQTT server outage that affects groov EPIC's MQTT client configured with Sparkplug payloads, after service is restored and the MQTT client starts sending out the updates stored...more
When PAC Control controller is restarted on groov EPIC, some types of numeric variables lose values
Knowledge Base - KB90704 - Published:
If a PAC Control strategy is running on a groov EPIC processor and has persistent numeric variables, when you cycle power to the EPIC, those persistent variables lose their values.
If PAC Control strategy contains HTTP Get/Post commands with SSL, PAC controller and other services may restart
Knowledge Base - KB90620 - Published:
If your PAC Control strategy contains HTTP Get or HTTP Post commands with SSL as the security mode, you may observe that various groov Manage services (including the PAC Controller) restart.
A simulated counter on a groov EPIC I/O unit or groov RIO provides erratic results
Knowledge Base - KB90673 - Published:
If a PAC Control strategy includes a groov RIO or groov I/O unit that is either not physically available to the system or is currently configured in the strategy with communication to the I/O unit...more
E2 periodically does not respond to a command
Knowledge Base - KB90668 - Published:
This issue is infrequent and only occurs roughly 0.01% of the time. If your control program is communicating to an E2 using Ethernet, periodically, you may observe that the E2 does not respond to...more
Tag status updates from MQTT are erratic or delayed when Sparkplug payload compression is enabled
Knowledge Base - KB90669 - Published:
If you configured MQTT Sparkplug to use payload compression (on the MQTT Sparkplug configuration page, you select either GZip or Deflate for the Compression field), you may notice that tag updates are delayed or erratic.
