42 N OMWT-SOFT-OPC Server Tags OMWT-SOFT-OPC Server
Dual Discrete Output: OUTPUTDISCn
(OMWT-DUALOUT)
online (R) - indicates if the device is communicating (0 or 1)
polltime (R/W) - how often to poll the device (in milliseconds)
nodaladdress (R/W) – (TCP/IP Receiver). The node address starts at 1.
For TCP/IP Receivers, the node address corresponds to the node
number for the TCP/IP connection. You can write to this parameter to
determine which node to send the output packet. (write 0 and OMWT-
SOFT-OPC will send to all nodes)
repeateraddress (R) – (Wireless mode) contains the location identifier of
the OMWT-REPEAT Repeater. If the sensor did not pass through a
repeater then the value is 0.
serialno (R) - registration number of the access/control reader
updatecount (R/W) – value is incremented whenever the sensor is updated.
outputa (R/W) – set to 0 or 1. Packet will be sent if TriggerOnB=0 option
is set in the INI file.
outputb (R/W) – set to 0 or 1. Packet will be sent when written.
out.status (R) – 1 – OMWT-SOFT-OPC is in the process of sending output
packets based on tries and interval; 0 – OMWT-SOFT-OPC has
finished sending the output packet.
out.interval (R/W) – time in milliseconds between OMWT-SOFT-OPC
sending the output packet.
out.tries (R/W) – the number of times OMWT-SOFT-OPC will send the
output packet. “-1” – never stops sending packets.
out.service (W) – When written to, OMWT-SOFT-OPC sends output
packets to the output device for training.
Note: when either outputa or outputb is written to, OMWT-SOFT-OPC will send
out output packets based on outtries and outinterval. It first sets outservice to 1,
and then to 0 when finished.
(R) – indicates that the tag is readable.
(W) – indicates that the tag is writeable only.
(R/W) – indicates that the tag is both readable and writeable. OPC Write operations
will either change an I/O point at the device, or an operation will be performed.
