APPENDIX: ELECTRONIC DATA SHEETS
(Programming Information)
Connection Object - Class 5 (05

), Instances 1, 2 and 3
This device supports Explicit Messaging (Instance 1), I/O Poll
(Instance 2), and I/O Bit Strobe (Instance 3).

If
Bus-Off Interrupt is true, the device automatically attempts to
recover from a bus-off condition if it is on-line and hasn’t been bus-off
since power-up, or if it has sent and received at least
Bus-Off Separation
messages since the last bus-off condition.

Output takes into account the On Delay, Off Delay, One Shot Delay,
and
Operate Mode. Switch state represents the physical location of
the limit switch.
Head Actuation Count increments each time the head is actuated.
When
Head Actuation Count reaches 80% or 100% of the Max Head
Actuation Count, a fault is added to the diagnostic object. Maximum
head actuation count is based on Mean Time Between Failure (MTBF)
data and therefore statistically some units could potentially fail earlier
than that, as well as operate well past that number.
The
Diagnose Nonactuated Switch service causes the device to
perform a self diagnostic on its sensing circuitry. The test is only
valid if the limit switch is in the nonactuated position. Running this
test is the only way to clear the
Diagnostic bit.
Assembly Object Data - Class 4 (04
HEX
), Instance 1
Attribute
Attribute ID
Access
Data
3
Get
Use Assembly Object Data to read diagnostic and output status. Data
bit 0 is output status, which is obtained from Attribute 1 of the
Presence Sensing Object. Data bit 1 is diagnostic status, which is
obtained from Attribute 4 of the Presence Sensing Object. The
remaining bits (2..7) are 0.
The I/O Poll and I/O Bit Strobe connections consume 0 bytes and
product 1 byte. The one produced byte is
Data.
