OMRON SP20 Timers Problem

jaichains · Feb 13, 2006

Hi All

I am converting an OMRON SYSMAC mini SP20 ladder code to s7-200. In the OMRON program there are three types of Timers defined

1)TIM = ON DELAY, Tenth of a second (no problem)
2)TIMM (20) = ON DELAY, Hundereth of a second (no problem)
3)T/M = ?????? (I cannot find this in manual)

If any one can help me in the third option timer, will be great. Thx.

ATIM(22) is a decrementing ON-delay timer with a hardware adjustment for the SV. On the SP16 and SP20, the hardware adjustment is the same for both ATIM(22) and ATM1(25).
ATM1(25) and ATM2(26) are available with the SP16 and SP20 only. Like ATIM(22), they are decrementing ON-delay timers and the SV can be set by hardware adjustments on the front of the CPU. Unlike ATIM(22), the SV can also be set in a word.

ATIM refers to an analog hardware timer built into SP16 and SP20. The "analog" feature refers to the fact that they do not have digital setpoints, but instead get their setvalues from analog potentiometers on the face of the SP16/20. If you are converting them to Seimens then just use an additional timer from the Seimens memory map and give it a digital setpoint.
