I’m trying to set a 3 single bits in my PLC (Allen-Bradley CompactLogix 1769-L18ER Cpu). To do this, I started using 3 different Allen-Bradley Write data blocks and 3 Device Command each. The device commands are set by 3 different trigger buttons… Then, I discover that it doesnt work like that (because when I press any button, the command set all the 3 bits at the same time).
Is there a way to send individual commands to set different bits individually? how to do that?
Thanks in advance,
