Hi
i have a modbus tcp buscoupler from phoenix contact - il eth bk di8 do4 2tx-pac.
the problem is that i can only read complete registers (function code 3 - modbus class 0).
Now i have to convert the 16bit word to single bits that i can use to see the state of my inputs.
if that works i have to do the same for my outputs because i cannot write a coil, i can only write the whole
register.
Please help me!
Thank u much.

Marcus what modbus node are using modbustcp?
Assume the phoenix contact is moving coils into a single register?
I will have to set up a modbustcp node as I think it returns a string.

I will have to set up a modbustcp node as I think it returns a string.
So if it is then you need to convert it to HEX and then create a new Buffer.
Then you should be able to access each bit.
This you would do in a function node.
If I have time I will have a go but there are real Devs. on the forum so someone might step in in mean time.

Hi Lawrance,
It is a buscoupler with an Ethernet port. It communicates over Modbus top. It's like wago 750-341.
But the problem is that I can only read and write registers. Not like common devices were I can read and write single coils or discrete inputs.
And now is my problem how to handle that register to get the boolean for each coil or input.

Marcus, is this the modbus node you are using to talk to the buscoupler
https://www.npmjs.com/package/node-red-contrib-modbustcp
https://www.npmjs.com/package/node-red-contrib-modbustcp
Can you provide a link to a data sheet/manual for the device?
Or is just a branded version of the Wago
Ok will put as solution something together hopefully by Wednesday!

Yes, this is the node i use. And it works.
I got the message and i can inject a number to write the register to the buscoupler.
Here the link to the datasheet:
On page 23 u find the supported function codes.
On page 26 u see the dynamic address table wich i use.

Hey Lawrence,
still i have no solution.
But maybe here is a way to solve this:
If i read a register at given adress its payload is 0.
But in binary it is: 00 00 00 00 00 00 00 00
Depending on the used module on my buscoupler i have 1, 2, 4, 8 or 16 inputs or coils that i want to read out.
that means i need for example only 8 digits of the 16 only.
But since i'm only a "glue-man" and no real programmer i need a function that
takes my msg.payload "0".
Makes the 16-bit binary from it - 00 00 00 00 00 00 00 00
and let me then choose how much of these binarys i want to use, depending on my inputs or coils
wich or hidden behind these binarys.
And then makes like the switch-node the same number of outputs.
sorry for my maybe bad english.

What do you get for some other example binary inputs ?
do you get 65280 = 0xFF00 = binary 11 11 11 11 00 00 00 00 ?
etc ? ie is it one bit per coil simply packed ?
Marcus Jelsch

You are right for example msg.payload = 65535 = 11 11 11 11 11 11 11 11 means all inputs or outputs are activated.

hi,
today i found out that in javascript i can do the following:
var i = msg.payload; // for example 20
var str = i.toString(2);
msg.payload = str;
return msg; // in javascript it returns - 10100
but this does not work in node-red??!! Why? This would be my solution.
Please help me.

Hi,
what result do you get?
That code assumes msg.payload is a number type. If msg.payload is actually a string representation of a number, then it won't work.
Here's an example flow that demonstrates the two:
[{"id":"5db4d51e.a24b2c","type":"function","z":"ad2c075c.52d3f8","name":"","func":"var i = msg.payload; // for example 20\nvar str = i.toString(2); \nmsg.payload = str;\nreturn msg;","outputs":1,"noerr":0,"x":311.5,"y":237,"wires":[["57e1b84a.a81e48"]]},{"id":"57e1b84a.a81e48","type":"debug","z":"ad2c075c.52d3f8","name":"","active":true,"console":"false","complete":"false","x":466,"y":239,"wires":[]},{"id":"1cdef660.e3210a","type":"inject","z":"ad2c075c.52d3f8","name":"Number 20","topic":"","payload":"20","payloadType":"num","repeat":"","crontab":"","once":false,"x":157,"y":225,"wires":[["5db4d51e.a24b2c"]]},{"id":"c7331061.38ccf","type":"inject","z":"ad2c075c.52d3f8","name":"String \"20\"","topic":"","payload":"20","payloadType":"str","repeat":"","crontab":"","once":false,"x":160,"y":272,"wires":[["5db4d51e.a24b2c"]]}]

Hi
I am a newcommer to node-red and have come late to this thread, but
you can test whether a particular bit is set using something like, for
the rightmost bit
if ((msg.payload & 1) != 0 ) {
// this will be executed if bit 0 is set
}
if ((msg.payload & 2) != 0 ) {
// this will be executed if bit 1 is set
}
if ((msg.payload & 4) != 0 ) {
// this will be executed if bit 2 is set
}
etc, where the test goes on against 8, 16. 32 etc.
Looking at the Function node I see that if you build an array of
messages and pass that to node.send then it sends the messages to the
outputs, sending no message if the entry in the array is null, so I
think you could send messages on the relevant outputs based on which
bits were set. If the payload coming is in actually a string, as
suggested by Nicholas then you would have to convert it to a number
first. Is that the sort of thing you are attempting to achieve?
There are more concise methods of writing the above code if it is what
you want to do.

which implies the msg.payload you are passing in is a string representation of the number, not a number type.
So you need to convert it to a number type before the .toString(2) trick will work:
if (typeof msg.payload !== 'number') {
msg.payload = Number(msg.payload);
}
var i = msg.payload; // for example 20
var str = i.toString(2);
msg.payload = str;
return msg;

Thank u Nick u made my day!!!!
Colin, i thought about a solution like yours, but the result that i want is a function node with
16 outputs - each output representing 1bit (a coil or a input).
Your solution is too much work because after processing i have to glue them together.

no idea if this helps - this function accepts a number 0 - 65535 and sets the various 16 outputs true or false according to the bits set.
Bit 15 is at the top and bit 0 at the bottom.

Now i have the next problem:
The 16 channels will now be processed and must be glued together to
a payload that i can write the a register with outputs.
U have an idea?

So whilst its not the answer to your question ( sorry!)
The way you are using context whilst still currently supported has been deprecated in favour of the way documented here:
http://nodered.org/docs/writing-functions#storing-data
So as you are writing this now I'd suggest using the new way to future proof yourself.

Thank you for the hint. But I'm bad in English. But what seems interesting to me is the global variables.
Do I understand it right, that this let me read the buscoupler, store the data in global variables, I manipulate them to my needs and then write back to my buscoupler. If this works, then I have to find out how to do this.

Hi
here is a modified version.
I have changed the split function to tag each message with its bit number... then used that in the join - rather than topic (only joining the bottom 8 as you had) - then converting back to a number as I expect that is what the register will want...
The changes to global that Mark mentioned are so thaht we can then persist the values externally to Node-RED at some point in the future... the current way of doing things won't go away for a good while (and may in fact stay as a volatile alternative for things you don;t want/need to persist)

Dave!! All Thumbs up!
Exactly what i want and ur code is much more lightweight than my horrible attempt.
Now i have the scaffolding for my next attempts to get the smarthome running.
If you are in germany we have a beer together!

Cheers !
warning - there are some very bad assumptions in that code ... like converting numbers to strings (to concatenate them all) and then converting back to a number. but I didn't want to change your code too much - so you could see what was going on., and relate it to your current thinking. Net is there are many, many ways that you can break that - but that is half the fun :-)

Hey,
i have a new problem i have an idea what the problem is but dont know how to solve this.
I get no output from the "Join 16"- function node. I think he is waiting for all payloads till he begin
working. But i cant wait for all tasks to continue. Do u have a solution for this problem?
Here is my actual flow.
For explanation:
First i read the inputsregister.
Second i split them into 16 payloads and publish to different mqtt topics
Then the magic should happen in openhab.
Openhab then publishs the state of the needed outputs.
But now i'm missing the polling that is needed to get all my payloads and write the whole register.
The magic stops at that "join 16"-functon node.
Please help me.

If you look at the function "join 16" you have the
line context.data[msg.bit] = msg.payload;
but I'm not sure you are setting "msg.bit" anywhere
You can check by
changing the output debug nodes e.g. "Task1" to Output "Complete msg object" so it will show you the complete msg object
or change the "join 16" so it reads...
node.warn("MSG.BIT"+msg.bit);
context.data[msg.bit] = msg.payload;

Hi Mark,
this is not the solution.
I think the Problem is that the MQTT Message is only send once.
After that the "Task"-nodes recieve no-more message and stop working.
A solution could be to store the value of the MQTT message ( 1 or 0 ) and then send all 16 bits periodically to
the "join16"-function-node.
But i dont know how. Could this be my solution?
Maybe someone has a hint for me and i first try myself.
Thank you!

Maybe a solution could be the trigger-node but it sends messages only twice.
Do you know how to send msg.payload every second like the
trigger-node but endless?

Hi Marcus,
Can you post the join side of your flow please?
