DESCRIPTION

 

 

 

 

 

 

 

Receive Squelch

00 .. 2147483647

Receiver squelch time in milliseconds.

 

 

 

 

A typical Receive Squelch is 00.

 

 

 

 

 

 

 

Pre-Transmit

00 .. 2147483647

Pre-transmission RTS on time in milliseconds.

 

 

Delay

 

A typical Pre-Transmit Delay is 15.

 

 

 

 

 

 

 

 

 

 

 

Post-Transmit

00 .. 2147483647

Post-transmission RTS off time in milliseconds. This must be at

 

 

Delay

 

least 2 character times for reliable communication. A typical

 

 

 

 

Post-Transmit Delay is 3 character times. Refer to Table 3 for

 

 

 

 

character times at various baud rates.

 

 

 

 

 

 

 

CTS Timeout

00 .. 2147483647

Clear to Send (CTS) transmit timeout period in milliseconds.

 

 

 

 

A typical CTS Timeout is 10.

 

 

 

 

 

 

 

ENQ Count

00 .. 32767

Default number of Enquiries (ENQs) to be retransmitted.

 

 

 

 

A typical value is 3.

 

 

 

 

 

 

 

NAK Count

00 .. 32767

Default number of Negative Acknowledgements (NAKs) to be

A typical value is 3.

 

 

 

 

 

 

 

ACK Timeout

00 .. 32767

Time duration to wait for an Acknowledgement (ACK) from the

 

 

 

 

host station (1/38 sec).

 

 

 

 

A typical value is 38 (1 second).

 

 

 

 

 

 

 

Master Address

00 .. 254

The address of the host (source) station with which this DPA is

 

 

 

 

communicating. Address 255 is reserved as a broadcast address.

 

 

 

 

 

 

 

RTU Address

00 .. 254

The destination address this RTU is to respond as (0 through

 

 

 

 

255). Address 255 is reserved as a broadcast address.

 

 

 

 

 

 

 

Valid Status

-128 .. 127

4 Entries indicating acceptable Status return values from the

 

 

 

 

host. These status values apply only to events issued by the

 

 

 

 

master, and not the status of the message.

 

 

 

 

These values are typically set to 00.

 

 

 

 

 

 

 

Event Buffer Size

1 .. 32000

Size of the ANSI event buffer.

 

 

 

 

A typical value is 1000.

 

 

 

 

 

 

 

Spontaneous

00 .. 32767

Spontaneous event timeout (in milliseconds) before a failure is

 

 

Timeout

 

logged.

 

 

 

 

A typical value is 5000.

A typical value is 3.

 

 

 

 

 

 

 

AI Retries

Number of analog event data retries before discarding event

 

 

 

 

(-1 try forever).

 

 

 

 

A typical value is 3.

 

 

 

 

 

 

 

EV Retries

-1 .. 255

Number of EV event data retries before discarding event

 

 

 

 

(-1 try forever).

 

 

 

 

A typical value is 3.

 

 

 

 

 

 

 

SPA Event Retries

-1 .. 255

Number of SPA events retries before discarding event

 

 

 

 

(-1 try forever).

 

 

 

 

A typical value is 3.
