A pure JavaScript implemetation of MODBUS-RTU (and TCP) for NodeJS
I tested with more than 9600 but its speed is equal to 9600. 9600 ~ 25-30ms 115200 ~25-30ms how to increase its speed?
Hi, If I want to read/write the values of more than 256 registers (e.g. 300 registers) starting at address 0 at once, are there any options I can set? Thank...
Modbus RTU specifies a 3.5 character time "silent interval" before the message frame. As far I have seen, this is not respected in this library. In case multiple read operations...
Hi, is it possible to use this library with Modbus RTU over TCP? I tried to do it using `connectTcpRTUBuffered ` but it wasn't working. I'm using [this converter](https://www.waveshare.com/rs485-to-eth.htm). The...
Hi, If for example, the getCoil function is not defined in the server vector, the read coil requests from a client are just ignored. I'm not sure if this is...
Hello, I'm doing a simple recall of some discrete inputs for GPI: ``` // create an empty modbus client var ModbusRTU = require("modbus-serial"); var client = new ModbusRTU(); var data...
Hi @yaacov, "modbus-serial" library is great, but it gives an error when used with "electronJS". I have found the solution to the problem after some long struggles. If you update...
Thank you for the library - it's really great. I'm experimenting with a model where I drive a GPIO high (RE) during the modbus write, and then drive it down...
Im trying to query my [smart meter](https://stromzähler.eu/stromzaehler/drehstromzaehler/fuer-hutschiene-geeicht/246/sdm72dm-v2-mid-3-phasen-zweirichtungs-drehstromzaehler-mit-rs485-und-s0), with a USB/RS485 adapter. ([Datasheet](https://xn--stromzhler-v5a.eu/media/pdf/93/17/d7/SDM72DM-V2.pdf) with modbus documentation) The data that is sended via this package looks wrong compared to the manufacturer software:...
