Chapter 4 Communication Protocol

4.2 Description of Communication Function

Example 1. Change the format of Modbus communication
◎
Change the communication format to address 2, Baud Rate to 19200, and format to 8,E,1; the procedure

is as shown below
Sequence of executed action
Change address to 2
Change Baud Rate to 19200
Change format to 8,E,1
Execute communication confirmation
action
Example 2. Floating blanking function (limited to ON/OFF operation mode)
◎
Note: Takes effect immediately after setting. Disconnect product output contact from the host before

setting, in order to prevent malfunction and damage.
Description: Only when the number of shielded beams exceeds the set value will the output be ON.

Setting: Default value 0 indicates turn off floating blanking function; maximum value cannot exceed half

the products number of beams.
Executed action
Set floating blanking number to 3
Example 3. Fixed blanking function (Limited to ON/OFF and measurement operation mode)
◎
Note: Takes effect immediately after setting. Disconnect product output contact from the host before

setting, in order to prevent malfunction and damage.
Description: Turn off designated beam detection. Non-shading/shading status of this beam will not affect

the output action.
Setting: Default 1 indicates that beam detection is turned on; 0 indicates that beam detection is turned off.

Executed action
Turns off detection for beams 1-4.
Example 4. Interlock/restart interlock function (limited to ON/OFF operation mode)
◎
Note: Takes effect immediately after setting. Disconnect product output contact from the host before

setting, in order to prevent malfunction and damage.
Description: Once shading occurs, output remains in OFF state; after full non-shading takes place again,

reset interlock function is executed, and only then is ON state restored at output.
Setting: Default 0 indicates that interlock function is turned off; 1 indicates that interlock function is turned

on.
Executed action
Turn on interlock function
