Associated with: Many DF1-specific items.
The Source attribute is common to many Status displays. The attribute indicates the location at which the item resides. The information shown varies, depending on the item.
The Source attribute displays the value Undefined if the item’s configuration is incomplete, in so far as the device with which the item is associated has not yet been specified.
For DF1 Scanners, information is displayed in this format:
<Port>:<Baud Rate>:<Data Bits><Parity><Stop Bits> <Node ID (this Master)>:
<PLC Type>,<Node ID (Slave)>
Example:
COM1:9600:8N1 7:Generic,14
(For a DF1 Scanner that is being used to scan generic Allen-Bradley PLCs via a DF1 slave that has the node ID 14. The DF1 node ID of this master is 7. The scanner uses a channel that has these settings: the channel communicates via port COM1, uses a 9600 baud rate, has 8 data bits, no parity (N) and 1 stop bit.)
For DF1 Analog Points, information is displayed in this format:
<Port>:<Baud Rate>:<Data Bits><Parity><Stop Bits> <Node ID (this Master)>:
<PLC Type>,<Node ID (Slave)>:<File Number>-<Address> <Data Type>
Example:
COM1:9600:8N1 7:Generic,14:12-8 Float
(For a DF1 analog point that is being used to scan floating-point data at address 8 within file number 12, on an Allen-Bradley PLC. The DF1 node IDs and communication details are as per the scanner example, above.)
For DF1 Digital Points, information is displayed in this format:
<Port>:<Baud Rate>:<Data Bits><Parity><Stop Bits> <Node ID (this Master)>:
<PLC Type>,<Node ID (Slave)>:<File Number>-<Address>.<Offset> <Data Type>
Example:
COM1:9600:8N1 7:Generic,14:22-6.2 Binary
(For a DF1 digital point that is being used to scan binary data at address 6, offset 2, within file number 22, on an Allen-Bradley PLC. The DF1 node IDs and communication details are as per the scanner example, above.)
