11.1 Touch probe function

11.1.1 Current position latch function
When the touch probe 1 turns on, the current position is latched. The latched data can be read with
communication commands.
(1) Reading data
(a) Rising latch data
TPR1 (Touch probe 1) rising latch data is read.
1) Transmission
a) For SLMP
The command 4020h, sub command 0001h, Index 60BAh, and Sub Index 0h are transmitted.
b) For Modbus/TCP or Modbus RTU
The function code 03h, start address 60BAh, and No. of Points 02h are transmitted.
2) Return
The latch data in the command unit is returned.
Data 32-bit length
(b) Falling latch data
TPR1 (Touch probe 1) falling latch data is read.
1) Transmission
a) For SLMP
The command 4020h, sub command 0001h, Index 60BBh, and Sub Index 0h are transmitted.
b) For Modbus/TCP or Modbus RTU
The function code 03h, start address 60BBh, No. of Points 02h are transmitted.
POINT
The current position latch function can be used with the point table method.
However, the current position latch function is disabled in the following condition:
Home position return
Manual operation (excluding home position return)
During JOG operation (excluding home position return)
The latched actual current position data can be read with communication
commands.
The read latched position data is equal to the travel distance as the starting
point is set to "0" when the roll reed display function is enabled. The output
value is the same as the current position of the state monitor.
