Basic function

basic function of 8-way network IO controller USR-IO808-GR

Remote control:

After powering network IO controller, user can directly realize remote control by USR Cloud. Take lamp control as example: user can realize lamp control by PC or APP on mobile terminal, and user can also directly open/close lamp by local switch. Remote control can realize all-weather and all-sided monitoring, save the cost of manpower and material resources.

Modbus protocol adaptation:

Can automatically identify Modbus RTU/TCP protocol in network side and respond data according to received protocol to realize response data as same format as received data.

Support Master mode and Slave mode for user to choose:

Default work mode of USR-IO808 is Slave mode and IO808 can be queried and controlled by Master device in Network side and RS485 side simultaneously in Salve mode. IO808 can also be configured into Master mode and Master mode supports connecting to multiple Modbus RTU devices by RS485 cascading connection. Master mode is suited to remote monitoring and control such as temperature and humidity monitoring of agricultural greenhouse.

Work mode

Master mode

In master mode, after IO808 receiving data, it will judge destination address firstly. If destination address is local address, IO808 will process data; if destination address isn’t local address, IO808 will forward data. In this mode, user can connect to multiple slave devices by RS485 cascading connection.

Slave mode

In this mode, IO808 can connect to master device or work as single device. In this mode, IO808 will analyse and process received data. If destination address is local address, IO808 will make a corresponding reaction; if destination address isn’t local address, IO808 will discard data.

Features:

Conditional control

Conditional control function supports user configuring the conditions to trigger IO changes. It can make using IO808 more flexibly and extend application scenario. User only needs to modify conditional control function register parameters, it will realize corresponding function. Conditional control function can provide convenience for project management.
