Modbus bit control over script

[Thinklight]

Hi,
Same ideas how can I control Modbus bit over script. Reading works for mee so I need write commands over Event script.

Code:

local adr1001 = mb:readregistervalue(1001, 'uint16')
grp.write('32/5/52', bit.band(bit.rshift(adr1001,8),0x1), dt.bool)  -- Baseino filtravimo laikmatis jei abu isjungti
grp.write('32/5/53', bit.band(bit.rshift(adr1001,9),0x1), dt.bool)  -- Filtravimas vyksta istisai
grp.write('32/5/54', bit.band(bit.rshift(adr1001,10),0x1), dt.bool)     --Vonios filtravimo laikmatis jei abu isjungti
grp.write('32/5/55', bit.band(bit.rshift(adr1001,11),0x1), dt.bool)     --Filtravimas vyksta istisai

Hi
As long it is register you have to build back the 2 byte and send it as register. Usually bit control is done via coil.

You should also use modbus mapper proxy functions if you want to access same RS485 port from several scripts. Otherwise you will get random access errors. https://forum.logicmachine.net/showthrea...53#pid1953
