Analog I/O Tag Definitions Appendix B
Ch0ConfigConfig
Bits INT All outputs Collection of channel’s individual configuration bits.
Ch0ConfigHoldForInit BOOL All outputs When set configures the channel to hold, or not change, until initialized with a
value within 0.1% of full scale of its current value when one of the following
conditions occurs.
1 = Module initial connection (power up)
2 = Module transition from Program mode back to Run mode
3 = Module reestablishes communication after a fault
Ch0ConfigRamp
AlarmLatch BOOL All outputs Enables latching for the rate alarm. Latching causes the rate alarm to remain
set until an unlatch service is explicitly sent to the channel or alarm.
Ch0ConfigLimit
AlarmLatch BOOL All outputs Enables latching for the clamp limit alarms. Latching causes the limit alarms
to remain set until an unlatch service is explicitly sent to the channel or alarm.
Ch0ConfigFault Mode BOOL All outputs Selects the behavior the output channel should take if a communication fault
is to occur. Either hold last state (0) or go to a user-defined value (1).
Ch0ConfigFaultValue defines the value to go to on fault if the bit is set.
Ch0ConfigProg
Mode BOOL All outputs Selects the behavior the output channel should take when transitioned into
Program mode. Either hold last state (0) or go to a user-defined value (1).
Ch0ConfigProgValue defines the value to go to on program if the bit is set.
Ch0ConfigRampTo
Run BOOL All outputs Enables ramping of the output value during Run mode between the current
output level and a newly requested output. Ramping defines the maximum
rate the output is allowed to transition based upon the configured
Ch0ConfigRampRate.
Ch0ConfigRampToProg BOOL All outputs Enables ramping of the output value to a user-defined program value,
Ch0ConfigProgValue, when set. Ramping defines the maximum rate the output
is allowed to transition based upon the configured Ch0ConfigRampRate.
Ch0ConfigRampToFaul
t BOOL All outputs Enables ramping of the output value to a user-defined Fault value,
Ch0FaultValue, when set. Ramping defines the maximum rate the output is
allowed to transition based upon the configured Ch0ConfigRampRate.
Ch0ConfigMax
RampRate INT All outputs Configures the maximum rate that the output value may change when
transitioning to either the Ch0ConfigFaultValue or Ch0ConfigProgValue if
either the Ch0ConfigRampToFault or Ch0ConfigRampToProg bits are set,
respectively, or in Run mode if Ch0ConfigRampToRun is set. In terms of
percent full-scale per second.
Ch0ConfigFault
Value REAL All outputs Defines the value, in engineering terms, the output should take if a
communication fault occurs when the Ch0ConfigFaultMode bit it set.
Ch0ConfigProg
Value REAL All outputs Defines the value, in engineering units, the output should take when the
connection transitions to Program mode if the Ch0ConfigProgMode bit is set.
Ch0ConfigLow
Limit REAL All outputs Defines the minimum value the output is allowed to take within the process. If
an output beneath the low limit is requested, the Ch0LLimit alarm is set and
the output signal will remain at the configured low limit.
Ch0ConfigHigh
Limit REAL All outputs Defines the maximum value the output is allowed to take within the process.
If an output above the high limit is requested, the Ch0HLimit alarm is set and
the output signal will remain at the configured high limit.
