Hello,
I have a question about Modbus TCP, is there any way to speeding up polling of devices?
In my project i have 7 devices Modbus TCP, i read from all and write to two. One of this device need heartbeat signal 1s ON 1s OFF over Modbus.
When i pooling all devices there is no time to write heartbeat signal (all communication takes more than 2s).
I use example program from Modbus library, duplicated to 7 devices.

Hello jakubsz,

the Modbus TCP FBs require several cycles to continue communication. Do you tried to reduce the time cycle interval of the task in the example project?

Best Regards
Eduard
