SPS interface
HLI
For the switching of the channel access on the axes and the axes display specific values on the PLC interface are available.
Suspend channel output | |
Description | The command of new position values from the interpolator to the physical axes (drives) is suspended. |
| MCControlBoolUnit, s. Beschreibung Control Unit |
Specifics | The released axes can be moved in the mean time by the logical axes of a different channel. |
Access | PLC liest Request + State und schreibt Command + Enable |

Commanded, requested, and return values | |
ST-Element | MCControlBoolUnit_SuspendOutput.X_Command MCControlBoolUnit_SuspendOutput.X_Request MCControlBoolUnit_SuspendOutput.X_State |
Data type | BOOL |
Range | [TRUE = output to the axes of the channel is suspended, FALSE] |
