Decision 119
Measurement ID 119 Decision
Measurement results are reported in pairs of value and decision. Measurement values are 32-bit wide
and decisions are 8-bit wide.
The measurement ID defines the byte position of each pair within the state information. The position
of the first word can be calculated as (80 + 5 * ID). For example, a measurement with ID set to 4 can be
read from byte 100 (high word) to 103 (low word) and the decision at 104.
In Range mode, the measurement results are updated after each frame is processed.
ASCII Protocol
This section describes the ASCII protocol available over the Ethernet and serial outputs. The protocol
communicates using ASCII strings and the output result format from the sensor is user-configurable.
Ethernet Communication
Gocator's Ethernet communication is bidirectional. Measurement results are sent on the Ethernet
output in one of two modes: Polling or Asynchronous. The ASCII protocol over Ethernet enables the
client to
• Switch to a different active configuration.
•
Calibrate, run and trigger sensors.
•
Receive sensor states, health indicators, stamps and measurement results
As with the Gocator Protocol there are separate channels for Control, Data and Health messages. The
Control channel is used for commands. The Data channel is used to receive and poll for measurement
results. The Health channel is used to receive health indicators.
The port number used for each channel is configurable. Each port can accept multiple connections, up
to a total of 16 connections for all ports.
Channels can share the same port or operate on individual ports. The default port number is 8190 for
all channels. The following port numbers are reserved for Gocator internal use: 80, 843, 2000 - 2100,
2500 - 2600, 3100 - 3250.
Asynchronous and Polling Operation
On the Ethernet output, the Data channel can operate asynchronously or by polling. Under
asynchronous operation, measurement results are automatically sent on the Data channel when the
sensor is in the running state and results become available. The result is sent on all connected data
channels.
Under polling operation, when the sensor receives a Get Result command, it will send the latest
measurement results on the same data channel that the request is received.
