Hello All,
my external application needs to analyze logread messages from the FX30 device via SSH connection, namely, it needs to watch for Modbus error codes.
For instance I noticed when RTU unit is not connected there is a timeout message like this
May 17 15:37:50 fx30s user.err Legato: =ERR= | modbus[1653]/components T=main | mbrSlave.c mbr_SlaveRegistersRead() 112 | Failed to read from UART1/UNIT2 (addr 00002) exception -110 (Connection timed out)
it’s clear for timeout there is code -110.
Could you please disclose the list of all possible codes and their description?
Thanks
