Ethernet Communication
OSA Remote Ethernet communication is designed to interface to a local intranet
through one of its Ethernet ports. A second Ethernet port is available for user
applications. The two Ethernet ports must be configured to be on separate
subnets.
A Copper Ethernet SFP Interface Module is provided and can be used with a
Cat6 shielded copper cable to provide 10/100/1000 Mbps communication. An
optional Fiber Ethernet SFP can be used with a fiber-optic cable to provide 1
Gbps Ethernet over fiber.
OPC UA
The OSA Remote software uses the OPC Unified Architecture communication
protocol for connectivity to external devices, HMIs, and SCADA systems.

Analog and Discrete
Input/Output
Each universal I/O channel on an OSA Remote can be independently configured
to operate in one of several modes. Depending upon the mode selected, OSA
Remote channels can interface to analog inputs and outputs with or without
HART, discrete inputs and outputs, or NAMUR sensors.
Operating Modes
The operating modes of the OSA Remote are listed below. These modes are
selected using the Bedrock IDE.
•
4-20 mA input (loop current max. of 25 mA) with HART
•
4-20 mA output with readback with HART
•
4-20 mA input (loop current max. of 25 mA) without HART
•
4-20 mA output with readback without HART
•
internally powered discrete output with readback (24 V excitation,
maximum current of 25 mA)
•
externally powered discrete output with readback (maximum current of
1 amp)
•
NAMUR
•
0-10 V voltage input
•
discrete input
OSA Remote channels may also be set to “Spare” in the Bedrock IDE for
configurations where a channel is not being used.
