Application Examples E-25
If Safe State is selected, you must click the Configuration Settings
tab and enter your Safe State data for each output word in
decimal. Then, whenever the SLC processor is placed into the
Program Mode or if communications is lost to the 1747-ACNR15
adapter, the outputs revert to the Safe State data you entered for
each output word.
2. Click APPLY.
3. Click OK to accept the rack connection.
Configure a Module Connection
Next, we need to configure a module connection for the 1746-NI8
input analog module.
1 . Right-click the 1746-NI8 module in the Scanlist Configuration
window.
2. Select Insert Connection.
A Connection Properties window appears.
3. Choose Exclusive Owner for the connection name.
For this example, we must choose M-file addresses for our 8
input analog module. The 1746-NI8 module must use Class 3
operation in a 1747-ACNR15 chassis. It requires 12 output words
and 16 input words. M-file words will be used for this in the
1747-SCNR scanner. M0:3.3 through M0:3.14 will be used for the
12 output words used to configure the module and M1:3.3
through M1:3.18 are used for the input information, including
actual analog data and analog channel status.
Refer to the SLC 500 Analog Input Module User Manual,
publication number 1746-6-8 for additional information on this
module. M-file words M1:3.0, M1:3.1, M1:3.2, M0:3.0, M0:3.1,
and M0:3.2 are reserved. The next available status address is
M1:3.600/02, since bits 0 and 1 are used for the rack connection.
