mb:handleslave()

84.

knxclient:step()

Example usage (TCP / master mode):

require('luamodbus')

mb = luamodbus.tcp()

mb:open('192.168.0.1', 5000)

mb:connect()

-- verbose output and select slave number 10

mb:setdebug(true)

mb:setslave(10)

-- read input from reg 1 to 5, get slave-specific data

mb:readinputregisters(1, 4)

mb:reportslaveid()

-- close serial connection

mb:close()

Example usage (RTU / master mode):

require('luamodbus')

mb = luamodbus.rtu()

-- open serial connection (half duplex)

mb:open('/dev/ttyS2', 38400, 'E', 8, 1, 'H')

mb:connect()

-- verbose output and select slave number 10

mb:setdebug(io.write)

mb:setslave(10)

-- read input from reg 1 to 5, get slave-specific data

mb:readinputregisters(1, 4)

mb:reportslaveid()

-- close serial connection

mb:close()

Read/write examples

-- multiple coil read

coil1, coil2, coil3 = mb:readcoils(10, 3)

-- multiple coil read to table

coils = { mb:readcoils(0, 3) }

Note: coil1 or coils[ 1 ] will be nil on error

-- multiple write

coil1 = true
