4.16 APP 485 Module
The Application module (APP 485) provides a solution to add user
applications to the ROC800-Series (ROC800) by simply installing a
module. The APP 485 module streamlines the installation process by
including all point types and screens associated with the application, and
the module is automatically recognized by ROC800 firmware. In
addition to the user application, the APP 485 module provides an
onboard RS-485 communications port that enables communications
without utilizing one of the built-in communications ports on the
ROC800.
APP 485 modules can house a variety of applications including Modbus
express and more. For more information about available applications,
contact your sales representative.
The APP 485 module enables the ROC800 to communicate directly
with field devices using the EIA-485 (RS-485) communications port
included on the module. The module serves as an interface between the
field devices and the ROC800. Supported protocols include Modbus
host and slave (RTU or ASCII) and ROC. LEDs on terminals A and B
provide you with visual feedback on communication activity status.
