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.

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
