Hello Dirk.
Yes, I'm writing my own modbus driver accessing directly to RS485 interfaces and in this manner I'm resolving all my problems.

Thank you and best regards.
Fabrizio

Thank you Dirk.
As soon I will be able to perform more tests, I'll be back with the information you requested.
(now I have to manage a bigger problem related to the maximum number of actions that can be performed by RevPI - refer to my post on the other thread related to this)

Thank you,
Fabrizio

Hello Dirk. I'm trying to communicate with more than 32 slave registers (I configured a Modbus RTU Master 150 to allow this configuration on Pictory), but it seems that no more than 32 actions can be performed by RevPi. I'll try to better explain my tests. I configured 48 actions on Pictory to acqui...

Hello Dirk. I'll try to give you more details about my necessity. To optimize the communication, I would like to send commands to read/write multiple registers at one time on every single slave (my modbus has a lot of slaves). This will be useful to reduce the polling interval of every connected sen...

Hello. I'm using a RevPi Flat S to communicate with 2 different modbus channels. To optimize the polling sequence, I would like to use the "Read Multiple Holding Register" and "Write Multiple Holding Register" function codes (3 and 16 respectively). I saw that it is possible to c...

Thank you Dirk.
I'll proceed with RevPi Flat.

Fabrizio

Hello Dirk. I find that the RevPI Flat has 2 different RS485 channels (I didn't found it previously!). So I suppose it can be used to manage my previous request (have 2 Modbus RTU Master channels). Are they completely independent and configurable with different communication settings? Thank you. Fab...

Thank you very much Dirk, for the useful information. I can also evaluate the use of another RevPi module, different from the Compact version I already used. The purpose is to have more than one Modbus RTU Master bus, so I can distribute all the sensors I have to manage on 2 buses. Could you suggest...

Thank you Dirk. When I configure for maximum 150 channels, the polling time adopted by RevPi for each channel is computed using the same logic used when I configure the standard master RTU? Then when you say "I don't think it's possible with the on-board tools we provide", you refer to my ...

Hello. I need to configure the RevPI to acquire about 100 channels (more or less) read from 50-60 different sensors. Is it possible using a RevPI compact? If yes, shall I have any limitation on configured polling time or any other drawback? At the moment, I'm successfully using RevPI compact to acqu...
