EXAMPLE 2 (continued)

8.3.4.2 The FAIL-SAFE STATE table controls the RTU outputs when the RTU detects a loss of

RF link. Because Example 2 has two entries in the SEND LIST, both FAIL-SAFE states

A & B are used. If RTU ID 1 detects a loss of RF link from RTU ID 2, outputs are

controlled according to FAIL-SAFE STATE A. If RTU ID 1 detects a loss of RF link from

RTU ID 3, outputs are controlled according to FAIL-SAFE STATE B.

8.3.4.3 I/O CONFIG is Input/ Output control of the RTU displayed in the Programming Software

I/O configuration screen.

8.3.4.3.1 In Example 2, RTU ID 1, Input 1 and Input 2; RTU ID 2, Input 1 and RTU ID3, Input 1

are configured to be inverted digital inputs.

8.3.4.3.2 In Example 2, all four outputs of RTU ID 1 are used, RTU ID 2, Digital Output 1 is used,

and RTU ID 3, Digital Output 1 is used. The initial condition  the state an output is

forced to upon power-on  is set for all relays to be open and all analog outputs to be

forced to 0 scale.

8.3.4.3.3 In Example 2, FROM ID is the ID number of the transmitting RTU; FROM ID numbers

are listed in the following 2 charts:

RTU ID 1 FROM ID (Transmitting RTU ID)

Digital Output 1 2

Analog Output 1 2

Digital Output 2 3

Analog Output 2 3

RTU ID 2 &RTU ID 3 FROM ID (Transmitting RTU ID)

Digital Output 1 1

8.3.4.3.4 FROM LOC is the number of the input controlling the output; FROM LOC numbers are

listed in the following chart:

RTU ID 1 FROM LOC (Controlling Input)

Digital Output 1 1

Digital Output 2 1

Analog Output 1 2

Analog Output 2 2
