1 Product Overview Remote IO system consists of network adapter module and extended IO module. The network adapter module controls fieldbus communication and it realizes communication link with host station controller or host computer software. The extended IO module controls the connection with the input and output sensors in the field. At first the Input IO module collects the field signals and sends it to the network adapter through the internal bus. Secondly the controller reads and processing data from the adapter through the field bus, and it writes the output data into the network adapter,...

1.2 Module Layout The ODOT-C series is a remote I/O module. The adapter module lies on the far left, and on the right are extended I/O modules. http:// www.odotautomation.com

1.3 LED Indicators The user can easily check the power state of adapter and I/O module, I/O module operating state, and the number of I/O channels though LED state. And the detailed indicator state should refer to the related adapter or IO modules. 1.4 Ground Protection There is one metal resilient sheet on the back of the module, which is used for effective grounding with the guide rail. The metal resilient sheet and the adapter PE (protective earthing) are connected internally. 1.5 Wiring http:// www.odotautomation.com

Use push-in method to connect single-wire or crimp terminal wires without any other tools. Users can save wiring time and ensure a safe operation regardless of wiring experience. The module equips with a wiring fixed end for cable harness, which is used to fix the cable when the IO module is wired with multiple cables. 1.6 Installation and Removal DIN-Rail Lock could be safely and reliably installed on 35 mm DIN-Rail. There is a manual closure buckle on the upper side of all modules for locking, and a manual buckle is on the left side of the adapter for locking the guide rail. http:// www.odotautomation.com...

When the module is removed, it needs to manually unlock the guide rail on the upper side of the module. For the adapter module, you also need to unlock the left rail buckle counterclockwise. http:// www.odotautomation.com

3.1 RS485 Interface Modbus RS485 port is 5 Pin screw terminals and its Pin definition is as below: Pin 1 2 3 4 5 Definition A+ BSGND Shield PE Description RS485 A+ RS485 BSignal Grounded Earthing of Shield Protect Earthing It is recommended to use cables with cores smaller than 1mm² . The cold-pressed terminal parameters are as follows: Switch1: DIP switch used to set the terminal resistance, pull up and down resistance.T: terminal resistance, U: pull up resistance, D: pull down resistance. The Switch2: DIP switch used to set the adapter module address.It is set by an 8-bit binary hardware dial...

(Special note: When the address needs to be set beyond 63, the address should be dialed to set it to 0, and the station address should be set in IO Config software) Reset: Module reset button, long pressing the button for more than 5 seconds and all parameters of the module will be restored to the default value. When the Reset button is activated, a green indicator will light up in the upper left corner of the button. Config: configured ports, it is standard MicroUSB interface for configuring device parameters and firmware upgrades. PWR Power State (GREEN) ON OFF STAT Module State (RED/GREEN)...
