node-red-contrib-sm-4relind 1.0.4
A Node-RED node to control Sequent Microsystems 4Relays-4Inputs Card
node-red-contrib-sm-4relind
This is the node-red node to control Sequent Microsystems Four Relays four Inputs 8-Layer Stackable Card for Raspberry Pi.
Manual Install
Clone or update the repository, follow the instrutions fron the first page.
In your node-red user directory, tipicaly ~/.node-red,
~$ cd ~/.node-red
Run the following command:
~/.node-red$ npm install ~/4relind-rpi/node-red-contrib-sm-4relind
In order to see the node in the palette and use-it you need to restart node-red. If you run node-red as a service:
~$ node-red-stop
~& node-red-start
Usage
After install and restart the node-red you will see on the node palete, under Sequent Microsystems category the fallowing nodes:
4relind
This node will turn on or off a relay.
The card stack level and relay number can be set in the dialog screen or dinamicaly thru msg.stack and msg.relay.
The output of the relay can be set dynamically as a boolean, number or string using msg.payload.
If you need to set all relays at a time, set relay number to 0 and send thru msg.payload a value that binary corespond to the state of the relays.
4relindrd
This node reads the status of a relay.
The card stack level and relay number can be set in the dialog screen or dinamicaly thru msg.stack and msg.relay.
This node will output the state of one relay if the relay number is [1..4] or the state of all relays if the relay number is 0
4relindin
This node reads the status of a optically isolated input.
The card stack level and input channel number can be set in the dialog screen or dinamicaly thru msg.stack and msg.channel.
This node will output the state of one input channel if the channel number is [1..4] or the state of all inputs if the channel number is 0
Important note
This node is using the I2C-bus package from @fivdi, you can visit his work on github here. The inspiration for this node came from @nielsnl68 work with node-red-contrib-i2c.Thank both for the great job.
