Sends/Executes Control Operations:
WRITE Binary Outputs
SELECT/OPERATE
DIRECT OPERATE
DIRECT OPERATE – NO ACK
Count > 1
Pulse On
Pulse Off
Latch On
Latch Off
Queue
Clear Queue
Explanation of 'Sometimes': Object 12 points are mapped to Virtual Inputs and Commands (Force
Coils). Both "Pulse On" and "Latch On" operations perform the same function in the 869 ; that is, the
appropriate Virtual Input or Coil is put into the "On" state. The On/Off times and Count value are
ignored. "Pulse Off" and "Latch Off" operations put the appropriate Virtual Input or Coil into the "Off"
state. "Trip" and "Close" operations both put the appropriate Virtual Input or coil into the "On" state if
a paired mapping is set, otherwise "Trip" will put into "Off" and "Close" will put into "On".
Reports Binary Input Change Events when no
specific variation requested:
□ Never
⊠ Only time-tagged
□ Only non-time-tagged
□ Configurable
Sends Unsolicited Responses:
□ Never
□ Configurable
□ Only certain objects
⊠ Sometimes
⊠ ENABLE/DISABLE unsolicited Function codes
supported
Explanation of 'Sometimes': It will be disabled
for RS-485 applications, since there is no collision
avoidance mechanism. For Ethernet
communication it will be available and it can be
disabled or enabled with the proper function
code.
