b. Complete ASCII scanning result (Complete beam status array) - 0x41 (‘A’ ASCII)
Sends to host the pattern with the ASCII information relative to each beam.
DS2 sends:
0x2A 0x41 aaaaaa bbbbbb cccccc ….. zzzzzz ss 0x0D
where:
aaaaaa = 6 ASCII codes (3 bytes) with information concerning the 01-21 photoelements
bbbbbb = 6 ASCII codes (3 bytes) with information concerning the 22-42 photoelements
cccccc = 6 ASCII codes (3 bytes) with information concerning the 42-63 photoelements
zzzzzz = 6 ASCII codes (3 bytes) with information concerning the last 21 photoelements
ss
= 2 ASCII codes (1 byte) indicating scanning status (see above)
c. Partial Binary scanning result (Measurements) - 0x42 (‘B’ ASCII)
Sends to host one or due numeric measurements.
DS2 sends (only one measurement):
0x02 0x04 0x42 m a s 0x03 x
where:
m = ASCII char linked to kind of measure (ASCII code linked to kind of measure get as sum of
char “A” and numeric value of kind of measure .
a = 1 byte with the (0 – 231)
x = checksum (complement to one of the Length, Type and Data field bytes sum)
s = 1 byte with scan state:
bit 0 = Power Led (0 OFF, 1 ON)
bit 1 = Failure Led (0 OFF, 1 ON)
bit 2 = Output Led (0 OFF, 1 ON)
bit 3 = Uscita PNP/NPN (0 disable, 1 enable)
bit 4 = short-circuit switching output (0 none, 1 yes)
bit 5 = stability (0 none, 1 yes)
bit 6 = n. a.
bit 7 = Programming Mode (0 local, 1 remote)
DS2 sends (two measurements):
0x02 0x06 0x42 m a n b s 0x03 x
where:
m = ASCII char linked to kind of measure (ASCII code linked to kind of measure get as sum of
char “A” and numeric value of kind of measure .
a = 1 byte with #1 measurement (0 – 231)
n = 1 ASCII code with #2 measurement (‘A’ + numerical value of the measurement type)
b = 1 byte with #2 measurement (0 – 231)
x = checksum (complement to one of the Length, Type and Data field bytes sum)
s = 1 byte with scan state:
bit 0 = Power Led (0 OFF, 1 ON)
bit 1 = Failure Led (0 OFF, 1 ON)
bit 2 = Output Led (0 OFF, 1 ON)
bit 3 = Uscita PNP/NPN (0 disable, 1 enable)
bit 4 = short-circuit switching output (0 none, 1 yes)
bit 5 = stability (0 none, 1 yes)
bit 6 = n. a.
bit 7 = Programming Mode (0 local, 1 remote)
