I'm hoping that on of the PLC adepts can help me with this question. I am going to be taking an analog weight signal from an MMI and using it in an existing MicroLogix 1200 as a permissive for a vacuum pump (0V = pump run, 10V = pupm stop). Do I need an analog input card, or can I place the analog signal into F8 as a value and use cascading timers to continually refresh the value (every 0.2s)? Thanks in advance,
