Definitions for secondary port on module

S or blank This parameter defines the functionality of the secondary port on the module.

S = back-up DNP slave port to the primary port.

Any other value will disable the port.

Baud rate value

0 to 65535 millisecond s

Secondary DNP Port Baud Rate: 300,

600, 1200, 2400, 4800, 9600, 19200,

384 (38400) , 576 (57600), 115

(115200)

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.

0 to 65535 millisecond s

0 to 65535 millisecond s

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.

Minimum time between receiving a request and transmitting a response.

Allows master time to disable transmitter on an RS-485 network.

Y or N This parameter defines if collision avoidance will be utilized on the primary

DNP slave port.

0 to 32000 Defines the minimum number of milliseconds to wait before transmitting a message after the CD signal is recognized as low.

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.

0 to 65535 Defines the number of milliseconds to wait before receiving characters after the CD signal is recognized as high.

7.9.1 Type

S or blank

This parameter defines the functionality of the secondary port on the module.

S = back-up DNP slave port to the primary port.

Any other value will disable the port.
