Re: Modbus change variable between virtual devices
Hi Dirk, Thank you for investigating into this error and having reported to us the outcome. As well pointed by @KTB-Vo2345 and @saardrimer we have also relied on RevPi to handle the Modbus functionallity and I find it rather peculiar and non-reasonable that you recommend us to work with libmodbus in...

Re: Fehlerhafte Werte in Prozessabbild ModBus TCP Master
Hello Boris, As raised by @KTB-Vo2345 we have also experienced similar problems with RevPi Modbus: Issue 1. We have two virtual devices which addresses get swap, i.e. "Device 1" suddenly starts to read registers of "Device 2" while "Device 2" keeps with the same behavio...

Re: Modbus change variable between virtual devices
Hi @KTB-Vo2345, Thank you for your reply and having raised the issue to our attention. We have carried further tests and do not find any reason for these swaps. In addition to this we are also experienced that some relays (controlled via Modbus) change state without any reason and in a random way. H...

Re: Modbus change variable between virtual devices
We have already experienced this behaviour twice without any reasonable explanation and without being able to replicate the issue. In our configurantion we have 5 virtual devices. Two of these devices have very similiar Modbus register map. We are pooling registers at 1000ms. For twice we have seen ...

Modbus change variable between virtual devices
Hi, We are using Revolution Pi on a product we have in our company. The device uses two virtual devices (both Modbus TCP slave) and read approx 15 registers on each device. Each device are very similar between them. We experienced a problem that RevPi swap register and variable between devices. Exam...

SNMP in RevPi
Hi,
I have a project that requires to integrate and equipment that communicates through SNMP (both to read and set values). Any straight forward way to integrate this with RevPi and PICtory? Any recommendation?
Thank you,

Re: OpenSource: Software
Hi,
I have the same concerns as Markus to ensuring its long-term support to the products where we are considering using RevPi. Dirk, can you please give us an answer on this?
Thank you,
Best regards,
Alex
