Page 5: Overview
(version 6.0 and above) an easy method of communicating with Allen-Bradley drivers or PLCs using the DF1 protocol. Opto 22 controllers can act as either a master or a slave device. They can be connected directly to the serial port on an Allen-Bradley PLC or to Data Highway networks using standard Data Highway interface devices. -
Page 6: Iocontrol Architecture
Insert the OptoIntegration CD to run the SETUP.EXE program. The setup wizard will create the folder Program Files\Opto 22\Allen-Bradley DF1 Integration Kit for ioControl. This folder contains all the subroutine and support files for the integration kit, as well as example ioControl strategies. -

Direct Serial Communication Wiring The cables used for connecting an Opto 22 controller to an Allen-Bradley PLC serial port are specified in the drawings below. The cable for a PLC5 requires a DB25 male connector on the PLC5 end. The cable for a SLC requires a DB9 female connector on the SLC end. -
Page 10: Direct Serial Communication
Opto 22 RS-232 serial connection to SLC5/04 RS232 port: Direct Serial Communication Full-duplex or half-duplex mode can be used to communicate directly between an Opto 22 controller and an Allen-Bradley slave device. Master subroutines only support half-duplex mode. Subroutines AB Typed Read / AB Protected Typed Logical Read Description AB Typed Read reads a block of data from a PLC 5 data file. - Page 11 Element 6 0 = Full-Duplex or Point-To-Point mode. -1 = Half-Duplex or Multidrop mode.
