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.

Summary
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.
