Hi All,

what is the maximum number of DCE parameters I can send out using the DCE modbus tcp module?

Thanks

Hi Roberto,

I'm not sure what you mean when you use the term parameters. If you're referring to the number of slave addresses, the DCE output is limited to 247 slave addresses. That is individual devices, virtual sensors, or NetBotz pods. This is based on a modbus specific limit. We are looking into potential workarounds but there is no way of getting around this limit per server at this time. If you're referring to how many registers can be output per slave device, as far as I have seen there are no limits.

 

Thanks,

Steve
