MC_ReadDIBit

To read an I/O input signal of robot controller. (Bit)

Graphic expression FB No. FB category
FB2136 Non motion

Input parameter

Parameter name Data type Valid range Default Omission (*)
AxesGroup Integer 1 or larger 1 No
Robot number
Specify an element number for the variable "Robots[n]" (variable in the data block "DB_DENSO_ROBOTS (DB2990)") mapped to the controlled robot (robot controller).
If a specified value exceeds the valid range, the CPU (PLC) stops.

The maximum valid range value is the maximum element number of the variable "Robots[n]". The default maximum element number is 10 but can be increased or decreased by the user.

Execute Boolean
  • True : Start
  • False : -
False No
Execution start
When the parameter is changed from False to True, this FB is executed.
IoType Integer
  • 0 : Hand I/O
  • 1 : Mini I/O
0

Yes

Type of DIO
Specify the type of DIO.
IoBitNo Integer
  • Hand I/O : 0 to 7
  • Mini I/O : 0 to 15
0 Yes
Bit number of I/O
Specify an I/O bit number. 
For details, refer to Function description.

(*) : For some parameters, entries can be omitted.

  • Yes : Entry can be omitted.
  • No : Entry required always.
