1. New product introduction:
Ethernet Remote I/O

2. Ethernet Remote I/O
The Horner APG Ethernet Remote I/O block is DIN-rail mounted and supports ModbusTCP. It is compatible with any standard ModbusTCP client (master).
The basic block consists of Power supply, Ethernet ports, 4 digital outputs and 8 digital inputs. The block is modular and supports the addition of several analog and digital I/O modules.

3. Ethernet Remote I/O Features
Up to 61 Ethernet I/O blocks can be connected to an Ethernet network at any point. The Ethernet I/O block and the Inline devices form one station. Up to 63 local bus devices can be connected to one station with the first 4 outputs and 8 inputs making up the first two devices.
Features
2 x Ethernet ports with auto negotiation and auto crossover. Connected via integrated 3 port switch.
(third port internal)
Speeds of 10Mbps and 100Mbps
Electrical isolation of Ethernet interface and logic.

4. Ethernet Remote I/O More Features
Integrated web server. (for configuration)
Autobaud detection of local bus. (500 kbps or 2Mbps)
Diagnostic and I/O status LEDs.
Eight 24VDC digital inputs.
Four 24VDC digital outputs.

5. Advantages of Ethernet I/O
Interoperability
Ethernet provides the opportunity to utilize multiple protocols over the same network wire.
Cost is reduced by taking advantage of an existing network.
Physical Connection
Standard RJ-45 jack connections.
Cables are easy to build. Factory made cables are readily available. A single standardized cable connects controller to I/O.
Electrically isolated, eliminating ground loop problems.
Ethernet network peripherals widely available.
The I/O is distributed reducing the need for terminating blocks.

6. Advantages of Ethernet I/O
Performance
Ethernet is fast. At 100Mbps, RS-232, RS-422, and RS-485 cannot compete.
The widely accepted standards make Ethernet flexible and increases scalability.
Troubleshooting
3rd party software tools for Ethernet give Ethernet I/O an added option for troubleshooting without having to buy extra hardware.

7. Overview of Configuration Options
Additional I/O modules can be added inline to the main block.
