HI again guys,
Still converting my PLC2 project and ran into an issue with a timer. I get that the PLC2 timers Start at the 030 address and that the bit 15 is the Done bit and bit 17 is the Enabled bit. I have also sorted out that the preset is stored at an address 100 more than the timer so Timer 040 preset is at 140 memory address.
My issue is this program is using an XIC 040/02 to trigger another bit. Is this a timer timing bit?The address referencing manual shows bit 0-3 as least significant bit, 4-7 as the middle digit and 10-13 as Most significant bit. My timer has a Preset of 999. What the heck is bit 2 doing?
I'm assuming its the ACCUM and setting that bit will trigger when that binary represented value is reached. Am I totally off base here? So its on when the LSB is 4, 5, 6 or 7 then off for 0, 1, 2, 3, 8, and 9? It looks as though it is being used as a pulse timer for old panel lamps for alarms. Not much description in this logic and no drawings so I'm not positive.
Thanks,
