Description
M8120 is the initialize pulse special internal relay.
When the CPU starts, five MOV(W) instructions store first-stage
parameters to data registers D0 through D4.
D0 (operation mode): 1 (100 to 10,000 Hz)
D1 (output pulse frequency): 30 (10,000 Hz × 30% = 3,000 Hz)
D2 (pulse counting): 1 (enable pulse counting)
D3 (preset value high word): 0
D4 (preset value low word): 1,000
Pulse data update flag M1 is reset (pulse data not updated).
R
M1
Pulse output complete flag M101 is turned off.
R
When M101 is turned on, three MOV (W) instructions store sec-
ond-stage parameters to data registers D1, D3, and D4.
D1 (output pulse frequency): 50 (10,000 Hz × 50% = 5,000 Hz)
D3 (preset value high word): 0
D4 (preset value low word): 3,000
S Pulse data update flag M1 is set (pulse data updated).
M1
When start input I0 is turned on, PULS1 starts to generate
3,000Hz output pulses in the first stage.
Pulse output complete M101 is turned off.
