Summary
DF1 Serial driver implements communication with Rockwell / Allen-Bradley devices using DF1 Protocol (SLC Families, and Micrologix) via Serial communication. It operates as a Master on serial networks. The communications blocks are dynamically created according to the pooling cycle defined on the AccessType for each Device Point.

Channels Configuration
Protocol Options
CheckSum: It defines the checksum currently being used by the device, whether it is CRC or BCC.
Settings
Set the fields according to your serial port configuration.
Nodes Configuration
Station Configuration
SlaveId: Set this field with the address of the slave device in the network.
Points Configuration
Point Address Configuration
The syntax for the DF1 Serial communication point is: <FileType><FileNumber>:<Address>
Where <FileType> indicates the memory area, the valid values are:
- N, for Integer
- B, for digital
- F, for real
<FileNumber> indicates the data address for the chosen file (up to 255).
<Address> indicates the address from the specific file which will read and/or write from PLC.
For I/O, the syntax is: <FileType>:<Slot>/<Address>
- O, for digital (output)
- I, for digital (input)
<Slots> indicates the position where the I/O module is connected to on the PLC
E.g.:
- F8:0
- N21:1
- B21:1/6
- I:0/0
