Using Control (Command) Points

The following control points are supported by the 4205/5205-TS-104S-PDPS
module:

Symbol Description

C_SC_NA Single-Point

Command

C_DC_NA Dual-Point

Command

C_RC_NA Step-Point

Command

C_SE_NA

Measured Normalized Point Command

C_SE_NB

Measured Scaled-Point Command

C_SE_NC

Measured Short Floating-Point Command

Each control point is identified by its Information Object Address. For each
control point, configure the following parameters:

Point #

- This is the information object address of the point. It identifies the point

in the network. This address must be unique for each Common ASDU Address in
the network.

DB Address

- This is the database location in the 4205/5205-TS-104S-PDPS

module associated with the point.

Monitor Point

#-Monitor DB Address- The user might (optionally) configure a

monitor point to be sent by the 4205/5205-TS-104S-PDPS module when it
receives the command for that specific point.

Example (C_SC_NA)

# Monitor Monitor Require

# Point # DB Address Point # DB Addr Select

# ------- ---------- ------- ------- -------

START

700 3200 100 1600 0

END

In the example above, each time the module receives a command for single-
command point 700, it sends a response containing a monitored single-point
(information object address 100 with the value at database bit-address 1600).

Require Select -

This parameter configures the point to require a Select request

before the Operate command.
