uint32_t translates as two uint16_t in big-endian format

|
MC_READ_COIL - coil values (by bits)
|
|
MC_READ_DISCRETE - discrete -//-
|
|
MC_READ_HOLDING_REG - read time/led/inch/outch
|
|
MC_READ_INPUT_REG - read ADC channel (regno is ADC ch number)
|
|
MC_WRITE_COIL - change single relay
|
|
MC_WRITE_REG - set/reset LED, restart MCU
|
|
MC_WRITE_MUL_COILS - change several relays
|
|
MC_WRITE_MUL_REGS - change Tms
