10.1 MotionDeviceCategoryEnumeration

MotionDeviceCategoryEnumeration provides the kind of motion device based on ISO 8373. It is defined in Table 114.

Table 114 – MotionDeviceCategoryEnumeration Items
Name Value Description
OTHER0Any motion-device which is not defined by the MotionDeviceCategoryEnumeration
ARTICULATED_ROBOT1This robot design features rotary joints and can range from simple two joint structures to 10 or more joints. The arm is connected to the base with a twisting joint. The links in the arm are connected by rotary joints.
SCARA_ROBOT2Robot has two parallel rotary joints to provide compliance in a selected plane
CARTESIAN_ROBOT3Cartesian robots have three linear joints that use the Cartesian coordinate system (X, Y, and Z). They also may have an attached wrist to allow for rotational movement. The three prismatic joints deliver a linear motion along the axis.
SPHERICAL_ROBOT4The arm is connected to the base with a twisting joint and a combination of two rotary joints and one linear joint. The axes form a polar coordinate system and create a spherical-shaped work envelope.
PARALLEL_ROBOT5These spider-like robots are built from jointed parallelograms connected to a common base. The parallelograms move a single end of arm tooling in a dome-shaped work area.
CYLINDRICAL_ROBOT6The robot has at least one rotary joint at the base and at least one prismatic joint to connect the links. The rotary joint uses a rotational motion along the joint axis, while the prismatic joint moves in a linear motion. Cylindrical robots operate within a cylindrical-shaped work envelope.

Its representation in the AddressSpace is defined in the table below.

10.2 AxisMotionProfileEnumeration

The AxisMotionProfileEnumeration provides the kind of axis motion as defined in Table 116.

Table 116 – AxisMotionProfileEnumeration
Name Value Description
OTHER0Any motion-profile which is not defined by the AxisMotionProfileEnumeration
ROTARY1Rotary motion is a rotation along a circular path with defined limits. Motion movement is not going always in the same direction. Control unit is degree.
ROTARY_ENDLESS2Rotary motion is a rotation along a circular path with no limits. Motion movement is going endless in the same direction. Control unit is degree.
LINEAR3Linear motion is a one-dimensional motion along a straight line with defined limits. Motion movement is not going always in the same direction. Control unit is mm.
LINEAR_ENDLESS4Linear motion is a one-dimensional motion along a straight line with no limits. Motion movement is going endless in the same direction. Control unit is mm.

Its representation in the AddressSpace is defined in the table below.

10.3 ExecutionModeEnumeration

The ExecutionModeEnumeration is defined in Table 118.

Table 118 – ExecutionModeEnumeration
Name Value Description
CYCLE0Single execution of a task program according to ISO 8373
CONTINUOUS1Task program is executed continuously and starts again automatically
STEP2Task program is executed in steps

10.4 OperationalModeEnumeration

ISO 10218-1:2011 Ch.5.7 defines the different possible Operational Modes. This enumeration is defined in Table 120.

Table 120 – OperationalModeEnumeration
Name Value Description
OTHER0

This value is used when there is no valid operational mode. Examples are:

- During system-boot

- The system is not calibrated (and hence cannot verify cartesian position values)

- There is a failure in the safety system itself

MANUAL_REDUCED_SPEED1"Manual reduced speed" - name according to ISO 10218-1:2011
MANUAL_HIGH_SPEED2"Manual high speed" - name according to ISO 10218-1:2011
AUTOMATIC3"Automatic" - name according to ISO 10218-1:2011
AUTOMATIC_EXTERNAL4"Automatic external" - Same as "Automatic" but with external control, e.g. by a PLC

Its representation in the AddressSpace is defined in the table below.
