Range Description
[Secondary Port] Definitions for secondary port on module
Type: M or S or blank This parameter defines the functionality of the
secondary port on the module.
M = emulate a DNP master port
S = back-up DNP slave port to the primary port.
Any other value will disable the port.
Baud Rate: Baud rate
value
Secondary 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.
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.
CD Time Before Receive: 0 to 65535 Defines the number of milliseconds to wait before
receiving characters after the CD signal is recognized
as high.

Range Description
[DNP Master] Definitions for DNP Master port if utilized.
Internal 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.
Initialize IED Database: Yes or No This parameter determines if the module will request
data from the processor to initialize the IED database
input data areas. If this option is utilized, ladder logic is
required to send the requested block from the
processor to the module.
Event Messages to PLC: Yes or No This parameter determines if event messages received
on the master port will be sent to the processor. If this
option is utilized, ladder logic must handle the 9903
blocks generated by the module.
