NetBotz Rack Monitor 750: Modbus TCP (Port 502) & RS485 port Reserved for future use

[SESA380953]

We have deployed NBRK750 with government customer, this one must be linked to BMS through Modbus TCP.

Two questions:

1. Could you give me a kind of guideline to catch how is the process to enable the Modbus TPC 502 Port on NBRK0750´s software?

2. Is there any date expectation to get enabled the RS485 port to link NBRK0750 to BMS ?

Thank you in advance.

Hi @SESA380953  

There is currently no modbus serial or modbus TCP option on the NetBotz 750. As you've noted, serial is reserved for future use 

I do know that modbus is planned for the future of the NetBotz 750 however there is no ETA at this time, sorry.

Thanks,

Steve

good afternoon sir, as a follow up on this issue,

On my site the client is asking why there is no modbus communication with the BMS system, I am not trained too extensively on NetBotz750's outside from adding devices, setting up alarms, Network parameters and time and dates.

From what I am reading on this thread, is it even possible to enable Modbus comms to their BMS system through the same Ethernet cable that is connected to the network?

Hi @Avila.Andres ,

At the time of the initial question and response, there was no modbus option on the 750/755 units. With the recent release of version 5.3.5 firmware, Modbus over IP is now an option on the NetBotz 750 and 755 models.
