Delta Electronics DVPDNET-SL manual PLC program

DeviceNet Network Scanner DVPDNET-SL

1.PLC program:

M1000
		MOV	D6037	K4M0 Send the content in D6037 to K4M0.
		MOV	D6038	K4M20 Send the content in D6038 to K4M20.
M8	M9				When X0 = On, start VFD-B.
		MOV	H2	D6288
M9	M8
		MOV	H1	D6288 When X1 = On, stop VFD-B.
M20
		MOV	H0100	D6287	When VFD-B runs, Y0 = On.
M21		MOV	H0000	D6287	When VFD-B stops, Y0 = Off.

END

2.Program explanations:

„The head instruction in the program, MOV, corresponds the content in D6037 to M0 ~ M15 and the content in D6038 to M20 ~ M35.

„See the table below for the corresponding relation between DeviceNet slave and PLC devices.

	PLC device	15	14	13	12	11	10	9	8	7	6	5	4	3	2	1	0

„When X0 = On, b8 of D6037 = 1. b8 of D6037 corresponds to M8, and therefore M8 = On. That is,

when X1 = On, M9 will be On.

„ D6288 corresponds to the control word in VFD-B. When M8 = On, execute [MOV H2 D6288] to run VFD-B. When M9 = On, execute [MOV H1 D6288] to stop VFD-B.

„b0 of D6038 corresponds to M20, b1 to M21, and so on. When VFD-B is in RUN status, b0 of D6038 =

1 and M20 will be On to execute [MOV H0100 D6287], which leads to Y0 = On. That is, when VFD-B is in STOP status, M21 will be On to execute [MOV H0000 D6287], which leads to Y0 = Off.
