shine ,按照您的指点，我编写的程序如下：
NETWORK1
A(
O "Switch_on"
O "Enable"
)
AN "Switch_off"
= "Enable"
NETWORK2
A "Switch_on"
FP "Enable"
JNB _007
L W#16#1
T MW 12
_007: NOP 0

NETWORK3

A M 13.0
S "YV1"
NETWORK4
A "Sensor_I"
JNB _002
L W#16#1
L MW 12
SLW
T MW 12
_002: NOP 0
A M 13.1
R "YV1"
S "YV2"
NETWORK5
A "Sensor_H"
JNB _003
L MW 12
SLW
T MW 12
_003: NOP 0
A M 13.2
S "Motor"
R "YV2"

NETWORK6
A "Motor"
L S5T#1M
SD T 10
A T 10
JCN _004
L MW 12
SLW
T MW 12
_004: NOP 0
A M 13.3
S "YV3"
R "Motor"
R T 10
NETWORK7
A "Sensor_L"
JCN _005
L MW 12
SLW
T MW 12
_005: NOP 0
A M 13.4
L S5T#2S
SD T 11
A T 11
R "YV3"
NETWORK8
请问您在编写程序时为什么还要每装入B#16#1?
我们不是已经初始化值了么？（W#16#1)
另外，怎么样返回去？可不可以在程序结尾处加JU MOO1指令直接跳转到
NETWORK 2
M001: L W#16#1
T MW12
的初始化程序？
敬请指教！！！
