Communication Module Configuration
[Section]/Item Range
Description
[MODULE]
General module configuration section
Module Name:
0 to 80
characters
This parameter assigns a name to the module that can be viewed using
the configuration/debug port. Use this parameter to identify the module
and the configuration file.
Module Type:
This parameter is fixed and not user-configurable.
It identifies the module type when a DNP.CFG file is imported in ProSoft
Configuration Builder (PCB).
[Section]/Item Range
Description
[DNP Slave]
DNP Slave configuration information
Internal Slave ID:
0 to 65534
This is the DNP address for the module. All messages with this address
from the master will be processed by the module.
Baud Rate:
Baud rate
value
Primary DNP Port Baud Rate: 300, 600, 1200, 2400, 4800, 9600,
19200, 384 (38400), 576 (57600), 115 (115200)
RTS On:
0 to 65535
milliseconds
This value represents the number of 1 ms increments to be inserted
between asserting the RTS modem line and the actual transmission of
the data.
RTS Off:
0 to 65535
milliseconds
This value represents the number of 1 ms increments to be inserted
after the last character of data is transmitted before the RTS modem line
is dropped.
Min Response Delay:
0 to 65535
milliseconds
Minimum time between receiving a request and transmitting a response.
Allows Master time to disable transmitter on an RS-485 network.
Modem:
Yes or No
This parameter defines if a dial-up modem is used on the secondary
DNP slave port. A modem cannot be used if the port is configured as a
Master.
Connect Timeout:
0 to 65535
Defines the number of milliseconds to wait for the CD signal to be set
high. The CD signal indicates a connection is made using a dial-up
modem.
First Character Delay:
0 to 65535
Defines the number of milliseconds to wait before sending the first
message after the connection is first made. This delay only applies to
the first packet sent to the modem.
Redial Delay Time:
0 to 32000
Defines the minimum number of milliseconds to wait before a redial
attempt is made by the slave.
Redial Random Delay:
0 to 32000
Defines a random millisecond time range to be added to the redial delay
time before the modem is accessed.
Idle Timeout:
0 to 65535
Defines the number of milliseconds the modem is inactive before it will
disconnect.
Phone Number:
ASCII String
Data
This field contain a null-terminated, ASCII character string used by the
dial-up modem. The string must contain all characters required by the
modem. An example string is ATDT1800222333. Maximum length is 34
bytes including the terminating 0.
Collision Avoidance:
Yes or No
This parameter defines if collision avoidance will be utilized on the
primary DNP slave port.
CD Idle Time:
0 to 32000
Defines the minimum number of milliseconds to wait before transmitting
a message after the CD signal is recognized as low.
CD Random Time:
0 to 32000
Defines the range of random time to be added to the CD Idle Time
before a message will be transmitted from the slave.
