H
A channel is in standby mode when a redundancy failover occurred due to an error in an IO-redundant
1
module.
For field devices as of HART revision 7
The quality code is formed from the 1st status byte (HART device status) and the "Device
variable status" (DVS) of the response frames (HART command 9).
