Appendix A
Output Tags
The 1756-IT16 is a dedicated input module that does not contain any output
data in the user connection. The module utilizes a Controlling Heartbeat for the
owner or a Listening Heartbeat for a Listen-Only connection.
Ch[x].CalGoodHighRef
BOOL
Indicates that a valid High Reference signal has been
sampled on this channel.
B13
Ch[x].CalBadHighRef
BOOL
Indicates that an invalid High Reference signal has been
sampled on this channel.
You must correct this condition to successfully calibrate
the module.
If calibration is aborted with an invalid High Reference
signal, the
I.Ch[x].CalibrationFault
tag is set for this
channel until a successful calibration is performed.
B14
Ch[x].CalSuccessful
BOOL
Indicates calibration on this channel is complete and the
Calibrating state has been exited.
This tag remains set after valid calibration as long as
connection is open.
B15
Ch[x].Data
REAL
Indicates channel data in Ohms or Temperature.
Any positive or negative value.
Determined by how you set the
scaling parameters on the channel.
For more information, see
.
Timestamp
DINT[2]
64-bit timestamp value that indicates when all eight
channels were last sampled.
This value is provided in terms of CIPSync time.
CIPSync Timestamp data
RollingTimestamp
DINT
16-bit timestamp that ‘rolls’ from 0…32,767 ms.
Compatible with existing PID/PIDE instructions to
automatically calculate sample deltas. With this module,
this PID/PIDE instruction uses the RPI because there is no
RTS available.
For more information on the Rolling Timestamp, see
0…32,767 ms;
where 1 ms = 1 count
