RTES - DNP3 MASTER/REMOTE EMULATOR

The following parameters are defined specifically for the configuration file of the DNP3 driver:

H=0

H=1

operate as a REMOTE unit (default)

operate as a MASTER device

Note: If this parameter is included in PORTn.CNF, it must appear before the I/o clusters are defined

F=t

t is the number of milliseconds of silence on the communication line to establish an end of transmission.(default is 3 character time)

R=id

if this parameter is used, id is the index of the RTES R register that operates as a run switch. The driver communicates only when this register is ON.

 

OPERATING AS a REMOTE (H=0)

X=n

number of seconds before expiration of a output block select command

U=0

U=1

do not send unsolicited 'responses'

send unsolicited 'responses' (default)

Note: This parameter is overridden by the DNP3 commands to unable/disable unsolicited responses.

 

I/O CLUSTER FORMATS IN 'REMOTE' MODE (H=0 or default)

Define binaries to send to the master on change of state

O=n ;n is number of clusters (max 16)

Each cluster is defined by 6 parameters:

Register,Quantity,ObjectID,MasterReg,AlarmReporting,Unused

Define analogs to send to the master when change exceeds deadband

S=n ;n is number of clusters (max 16)

Each cluster is defined by 6 parameters:

Register,Quantity,ObjectID,MasterReg,AlarmReporting,DeadBand

In the above clusters:

Register

the id of first RTES variable to be used

Quantity

the number of consecutive registers (max 16)

ObjectID

The Variation and Group the variables will assume
You define this parameter as 256*VAR+GRP

MasterReg

the starting position of these points in the array at the MASTER

AlarmReporting

the index of a RTES R register to indicate a communication failure

DeadBand

the index of the first of a set of RTES R registers to contain the deadband values for each corresponding analog point.

Unused

a reserved position (use 0)

 

Define control outputs

p=n ;n is number of clusters (max 16) *** note lower case p ***

Each cluster is defined by 3 parameters:

Register,Quantity,OutputBlockIndex

In the above cluster

Register

is the id of a RTES variable that will represent the TRIP/CLOSE outputs

Quantity

is the number of TRIP/CLOSE pairs

OutputBlockIndex

is the starting output block index used at the master station to reference these outputs.

 

OPERATING AS a MASTER

W=t

number of milliseconds between commands

X=s

number of seconds between class 0 data polls.

s=n

number of remote stations. (Max 16)

 

Each station is defined by 15 parameters in the following order:

Station id

decimal value of the remote station number

Command register

RTES R register to control the polling

If C=0 polling occurs when this register is on.

If C=1 a poll takes place when this register is on and the driver turns it off after completion.

The register immediately below will report the decimal representation of the IIN word received from this remote.

First binary input

id of the first RTES variable that will receive the status of the binary inputs from this remote

Quantity of binary inputs

  

First analog input

id of the first RTES variable that will receive the values of the analog inputs from this remote

Quantity of analog inputs

  

First control output

id of the first RTES variable that will control the TRIP/CLOSE operation at this remote

Quantity of control outputs

number of pairs of TRIP/CLOSE controls

Pulse duration

in milliseconds

First analog output

id of the first RTES variable that will send their values to the analog outputs of this remote

Quantity of analog outputs

  

First counter

id of the first RTES variable that will receive the values of the counters from this remote

Quantity of counters

  

Communication alert register

Turns true when master station does not respond

Unsolicited mode register

When you set this register to 1, this driver sends to the remote the command to turn the unsolicited mode on for classes 1, 2 and 3 data. When you set this register to 2, this driver sends to the remote the command to turn the unsolicited mode off. This driver returns the register to 0 after command acknowledgement.
The register immediately following the Unsolicited mode register is used to tell the driver to force an 'all poll' at the next poll interval. You turn it on, it goes off when after the requested is recorded.

I/O CLUSTER FORMATS IN 'MASTER' MODE (H=1)

Define variables to send to the remotes on command:
S=n ;n is number of clusters (max 16)

Define variables to read from the remotes on command
G=n ;n is number of clusters (max 16)

Each cluster is defined by 6 parameters:
Var/Grp,Quantity,RemoteID,RemotePos,AlarmReporting,CommandReg

Var/Grp is (Variation)*256+Data_Object for the variable (object) used.
ie : for Data object 01, Variation 2 ("binary input with status"), use 513

RTES variables:
The parameter used as RTES register index to exchange variables over DNP3 is coded as follows to indicate which type of variable is used:

0-9999         R registers
10000-19999    I registers
20000-20000    O registers
30000-39999    A registers (converted value)
40000-49999    Y registers (converted value)
50000-59999    A registers (raw value)
60000-69999    Y registers (raw value)
TCP/IP
DNP3 is available for operation over TCP/IP or UDP (option).

The default tcp port is 502. This may be changed by adding in the configuration file : V=port#

When operating in MASTER mode, the IP's of the remote stations must be defined in the configuration file.

Each remote IP is defined by a "P" cluster of 5 numbers : [station id], [IP]

For example, the following defines a remote station ID=45 at 192.168.0.12 and a remote station ID=78 at 192.168.0.14. Note that the 5 numbers must be separated by a comma or a space (not a dot). 

P=2 45,192,168,0,12 78,192,168,0,14
