AnchorPLC For Opto 22® is a logic runtime system for control programs developed using our AnchorPAW workbench. With these programs, users direct the operation of processes, local instrumentation, and hardware via the OPTO 22 SNAP Ultimate Brain® and OPTO 22 SNAP Ultimate I/O modules. Ladder Logic and Structured Text, IEC 61131-3 control languages, are used in programming the runtime system.

With AnchorPLC’s Modbus Master capability, the OPTO 22 Ultimate Brain can access remote points via Modbus/TCP (Ethernet) and Modbus/RTU to provide true distributed industrial control. This product combination offers HUGE programming space for IEC-61131-3 embedded control.
The Ultimate Brain version of AnchorPLC for OPTO provides the functions of a standard Modbus/RTU Master or Slave by querying or responding via Modbus/RTU or Modbus/TCP queries for status and data with unprecedented ease.

RS-485, RS-232 Serial Modules


The Modbus/RTU protocol is supported for the RS-232 or RS-485 SNAP serial modules. Multiple serial module ports can be designated as slave or master Modbus/RTU ports and the Modbus/TCP protocol is available for master and slave. Also, custom protocols are implemented via AnchorPLC Stream I/O from RS-232 and RS-485 Serial Modules.

AnchorPLC is truly easy to master. The flexibility offered to the logic environment is unmatched.
