Device part of <Figure 1> input Com Port(COM1), Baud Rate(1200), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to controller.
Baud rate of KEYENCE LS-3002/3004 model can set as follows:
1) Open cover of front panel.
2) Please set jumper among 9 socket.
3) Baud rate according to jumper position : 75, 150, 300, 600, 1200(default), 2400, 4800, 9600, 19200bps.
KEYENCE LS-3002/3004 communication driver read schedule
Read schedule setting parameters are as follows:
1) Station – Don't care.
2) Read command – Command = H, M.
H – read of status information, ( refer to <Table 1> )
M, space, ... – read of current measurement.
3) Read start address – Don't care.
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – Fixed to 1. ( H – 5, M - 1 )
Read schedule example)
READ, 0, M, 0, 0, 1,
<Table 1> is data saving address and contents for 'H' read command.
| Data saving address | Contents | Remarks |
| Start addr + 0 | number of sample | 8, 16, 32, 64, 128, 256, 512 |
| Start addr + 1 | measurement mode | 1 = DIA, 2 = EDGE1, 3 = EDGE2, 4 = GAP, … |
| Start addr + 2 | Reference Value(Standard) | 5 digit integer(0 ~ 99999) |
| Start addr + 3 | Upper Limit Value | 4 digit integer(0 ~ 9999) |
| Start addr + 4 | Lower Limit Value | |
| <Table 1> Data saving address and contents for 'H' read command | ||
KEYENCE LS-3002/3004 communication driver store the same data in WORD, DWORD, FLOAT memory, but the data format are different.
You can read, write by using 'writing settings'.
Digital Write
Digital write and analog write have the same setting parameters except output value.
Analog Write
Analog write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Don't care.
3) ADDRESS Data saving start address when M, H write command.
4) Extra1 Write command.
H – read of status information, ( refer to <Table 1> )
M – read of current measurement,
B : stop of current measurement,
D : setting to DIA measurement mode,
E : setting to EDG1 measurement mode,
F : setting to EDG2 measurement mode,
G : setting to GAP measurement mode,
S : setting of Reference value(Standard),
U : setting of Upper Limit value,
L : setting of Lower Limit value,
MANUAL : set to Manual Operation mode,
SAMPLE : number of Sample setting. (Output value : 1 ~ 7, refer to <Table 2>)
5) Extra2 Don't care.
<Table 2> is output value and number of Sample for 'SAMPLE' write command.

Write example 1)
PORT:0, station:0, ADDRESS:0012, Extra1: M, Extra2 : 0
The setting parameter shown above is current measurement reading example. After reading, the readed value save at 12 WORD, FLOAT, DWORD memory.
Write example 2)
PORT:0, station:0, ADDRESS:0000, Extra1: D, Extra2 : 0
The setting parameter shown above is setting example to DIA measurement mode.
Write example 3)
PORT:0, station:0, ADDRESS:0000, Extra1: E, Extra2 : 0
The setting parameter shown above is setting example to EDG1 measurement mode.
Write example 4)
PORT:0, station:0, ADDRESS:0000, Extra1: SAMPLE, Extra2 : 0, Output value = 3
The setting parameter shown above is number of Sample setting example. (setting Sampe = 32 )
Write example 5)
PORT:0, station:0, ADDRESS:0000, Extra1: S, Extra2 : 0, Output value = 12345
The setting parameter shown above is Reference value setting example. (setting value = 12.345 mm (1.2345 inch) )
