DVP-ES2/EX2/SS2/SA2/SX2/SE&TP Operation Manual - Programming 2.9 S Relay Initial step relay Starting instruction in Sequential Function Chart (SFC). S0~S9, total 10 points. Zero return step relay Returns to zero point when using IST instruction in program. Zero return step relays not used for IST instruction can be used as general step relays. S10~S19, total 10 ponits. Latched step relay In sequential function chart (SFC), latched step relay will be saved when power loss after running. The state of power on after power loss will be the same as the sate before power loss. S20 ~ S127, total 108 points. General purpose step relay General relays in sequential function chart (SFC).
They will be cleared when power loss after running. S128 ~ S911, total 784 points. Alarm step relay Used with alarm driving instruction API 46 ANS as an alarm contact for recording the alarm messages or eliminating external malfunctions. S912 ~ S1023, total 112 points. 2.10 T (Timer) The units of the timer are 1ms, 10ms and 100ms and the counting method is counting up. When the present value in the timer equals the set value, the associated output coil will be ON. The set value should be a K value in decimal and can be specified by the content of data register D. The actual set time in the timer = timer resolutionЧ set value Ex:
If set value is K200 and timer resolution is 10ms, the actual set time in timer will be 10ms*200 = 2000ms = 2 sec. General Timer The timer executes once when the program reaches END instruction. When TMR instruction is 2-24 OFF STOP RUN Special ES2 SA2 Latch Function SS2 SX2 Attrib.
