2BPROTOCOL FEATURES
0BHARRIS 5000 PROTOCOL
between the master node and slave node. This field contains the addresses of the
points requested by the master node or the result produced by the slave.
Finally, the field
LRC
(Longitudinal Redundancy Check) contains an error detection
code. It is one byte long and contains the result of the XOR of all the characters of the
message. When a device transmits a message, calculates that value and adds it to the
data package. The device receives the message, performs the same calculation and
compares its result with the code received. If the same result is produced, the data
package is considered correct, while a difference causes the package to be considered
wrong.
6.2.2. PORT DEFINITION
An HR5000 RTU is organized in ports with a maximum capacity of 7 ports. Each port
can be configured as one of the following types: Analog Inputs, Accumulators, Indication
Inputs and Control Commands, Up / Down Outputs, Analog Outputs and SOE
(sequence of events).
In some of the messages sent by the master, we find references to the index of the port.
This reference is not an absolute reference; it is relative to the type of port.
For example if we have two ports, 6 and 7, configured as “Up / Down” and we want to
refer to the first one, we refer to it as port 0, the will refer to 7.
As Analog Inputs and Accumulators ports are treated with the same function, both are
considered as the same type in terms of relative port numbering.
Each port has 3 status bits which reflect the status of each port. This information is sent
to the station master on the content of the response to some commands. These 3 bits
are:
OL: Off Line. Port out of service.
PF: Power Fail. Port reset.
MF: Failure of internal transfer of the port, or number of changes requested does
not match the reported.
