Working Mode Of Modbus RTU IO Module

Rich Working Mode-Work with Various Automation Scenarios

Normally ON Normally OFF
The upper computer controls to close/open, then relay responds immediately
Flash ON Flash OFF
Flash ON: send command to relay, the relay disconnects after being connectd
Flash OFF: send command to relay, the relay connects after being disconnected
Actual time = set number * 0.1, unit: second

Local Linkage
Corresponding actions(linkage follow or state reversal) according to DI

2 Device Linkage
2 devices are used together, DI of device 1 can remotely control DO of device 2

Working ModeInput actionOutput actionNote
NOLock LinkageActive (inactive)Closed (disconnected)Input channel N corresponds to output channel N
Lock LinkageActive (inactive)Overturn (no action)Input channel N corresponds to output channel N
All Channel Lock LinkageActive (inactive)Corresponding output closed; others openInput channel N corresponds to output channel N
2Device NOLock LinkageDevice 1 input valid (invalid)Device 2 output closed (open)Mutual control between 2 devices with the same 485 address
2Device Lock LinkageDevice 1 input valid (invalid)Device 2 output overturn (no action)Mutual control between 2 devices with the same 485 address
Free Condition ControlMultiple input condition selection (up to 4 logics can be set)Arbitrary multi-channel input and output channel controlUse multiple registers as input, perform operations (AND or NOT, threshold comparison) to control multiple outputs
