What is Modbus Network Capacity in NUC or JIGSAW?

Thays Zanin 1 year ago in Devices / Modbus updated by ComfortClick Support 1 year ago 1

Good Morning!

I've been researching the Comfortclick website, but I have some doubts about Modbus.

Here are the questions below and also an outline of the basic concepts for Modbus RTC and TCP/IP:

1. Is there any difference in capacity between a NUC or JIGSAW?
2. Is there any difference in capacity between an RS-485 RTU or TCP/IP?
3. Is there any limitation or does bOS Comfortclick comply with the Modbus standard, ie up to 32 devices [without repeater] or 247 [with repeater]?
4. Is there the possibility of limitation by the manufacturer/device, having limited the amount of modbus addresses?
[As shown in the example on the Comfortclick page:

Thanks!

Hello,

1. Regarding Modbus, there is no big difference, both servers could handle similar number of Modbus devices (but number of Modbus devices is not the key factor it is number of registers/data points) if it is a commercial project I recommend you to use at least Grinder Black or even better Sledgehammer, due to professional server features (e.g. full disk backup, remote control of server hardware through web interface...)

2. No difference.

3. bOS comply with Modbus standard so you can integrate maximum number of devices according to Modbus standard.

4. Do not fully understand last question.

Best regards
