basic function of 4-way io controller

 

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 man power 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.

Modbus protocol adaptation of 4-way io controller

 

Support Master mode and Slave mode for user to choose:

Default work mode of USR-IO424T is Slave mode and IO424T can be queried and controlled by Master device in Network side and RS485 side simultaneously in Salve mode. IO424T 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 IO424T receiving data, it will judge destination address firstly. If destination address is local address, IO424T will process data; if destination address isn’t local address, IO424T will forward data. In this mode, user can connect to multiple slave devices by RS485 cascading connection.

master mode of 4-way io controller

 

 

Slave mode

In this mode, IO424T can connect to master device or work as single device. In this mode, IO424T will analyse and process received data. If destination address is local address, IO424T will make a corresponding reaction; if destination address isn’t local address, IO424T will discard data.

Features:

Conditional control

Conditional control function supports user configuring the conditions to trigger IO changes. It can make using IO424T 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.

features of 4-way io controller
