以下是 主程序：
LD SM0.0
CALL 急停:SBR3

LD SM0.0
= L60.0
LD X1按钮:I2.1
= L63.7
LD 铺设连道急停:V0.1
= L63.6
LD X1光电眼1:I2.0
A X1光电眼2:I4.2
= L63.5
LDN X2光电眼:I2.3
= L63.4
LD 手动铺设连道1反馈:I1.2
= L63.3
LD X1光电眼2:I4.2
= L63.2
LD L60.0
CALL SBR_4:SBR4, L63.7, L63.6, L63.5, L63.4, L63.3, L63.2, 手动铺设连道1:Q2.0, 手动铺设连道2:Q2.1, 变频器启动:Q0.0

LD SM0.0
= L60.0
LD X2按钮:I2.4
= L63.7
LD 铺设连道急停:V0.1
= L63.6
LD X3光电眼1:I2.6
A X3光电眼2:I2.7
= L63.5
LDN X2光电眼:I2.3
= L63.4
LD 手动铺设连道2反馈:I1.3
= L63.3
LD X3光电眼1:I2.6
A X3光电眼2:I2.7
= L63.2
LD L60.0
CALL SBR_4:SBR4, L63.7, L63.6, L63.5, L63.4, L63.3, L63.2, 手动铺设连道2:Q2.1, 手动铺设连道3:Q2.2, 变频器启动:Q0.0

完了，整个程序 的动作基本上 都要反复调用
