LM master modbus, PLC slave

[Simuzer]

hi all.

I have a modbus project that LM is Master and Wago PLC Slave. Using word and bits..

I read and write data as word but i don't read and write any bit of word..

I dont use modbus mapping . I love script more easy.

Code:

require('luamodbus') mb = luamodbus.tcp() mb:open('192.168.1.102', 502) mb:connect()   -- -- --     value = grp.getvalue('32/1/2')   mb:writeregisters(0, value)     value = grp.getvalue('32/1/3')   mb:writeregisters(1, value)   value = mb:readregisters(2)     grp.update('32/1/4', value)   -- -- --   -- -- --     value = grp.getvalue('32/1/5')   mb:writeregisters(3, value)     value = grp.getvalue('32/1/6')   mb:writeregisters(4, value)   value = mb:readregisters(5)     grp.update('32/1/7', value)   -- -- -- -- bolean --    valuew6 = mb:readregisters(6) --read w6   -- w6.0 -- read 0. bit of w6     if (grp.getvalue('32/1/8')) then         valuew6 = valuew6 or 1                -- set » xxxx xxxx xxxx xxx(1)   else     valuew6 = valuew6 and 65534        -- set » xxxx xxxx xxxx xxx(0)   end   -- --   -- w6.1 --  read 1. bit of w6     if (grp.getvalue('32/1/9')) then         value6 = value6 or 2                -- set » xxxx xxxx xxxx xx(1)x   else     value6 = value6 and 65533        -- set » xxxx xxxx xxxx xx(0)x   end     -- --   -- w6.2 -- write 2. bit of w6      bValue = (value6 and 4)            -- set » 0000 0000 0000 0(x)00      if (bValue==4) then        grp.update('32/1/10', true)       -- set » xxxx xxxx xxxx x(1)xx    else        grp.update('32/1/10', false)       -- set » xxxx xxxx xxxx x(0)xx    end   mb:writeregisters(6, value06)     grp.update('32/1/11', value06)   mb:close()
