Data Area
In general, TcCOM objects can contain data areas that can be used by the environment (e.g., by a PLC instance or by the TwinCAT I/O area). For TwinCAT MC3 TcCOM objects, you have a choice of data structures to use via the Data Area tab.
Pulse Width Current Drive (MDP250) (both channels) / PWM Inputs
Enable (default) | Name | Type | Description |
|---|---|---|---|
| Channel 1 Ready to enable | BIT | Channel 1: The terminal indicates that it is ready for operation. |
| Channel 1 Warning | BIT | Channel 1: A warning has occurred. |
| Channel 1 Error | BIT | Channel 1: An error has occurred, and the output drivers are disabled. |
| Channel 2 Ready to enable | BIT | Channel 2: The terminal indicates that it is ready for operation. |
| Channel 2 Warning | BIT | Channel 2: A warning has occurred. |
| Channel 2 Error | BIT | Channel 2: An error has occurred, and the output drivers are disabled. |
| WcState | BIT | Working counter |
| InputToggle | BIT | Level change upon receipt of a new telegram. |

Enable (default) | Name | Type | Description |
|---|---|---|---|
| Channel 1 Enable dithering | BIT | Dithering for Channel 1 is "enabled." |
| Channel 1 Enable | BIT | Enable dithering for channel 1. |
| Channel 1 Reset | BIT | Resetting an error on Channel 1. |
| Channel 1 PWM Output | INT | Output from the PWM terminal on channel 1 |
| Channel 2 Enable dithering | BIT | Dithering for Channel 2 is "enabled”. |
| Channel 2 Enable | BIT | Enable dithering for channel 2. |
| Channel 2 Reset | BIT | Resetting an error on Channel 2. |
| Channel 2 PWM Output | INT | Output from the PWM terminal on channel 2. |
Notice | |
Warning in the error log window caused by selected entries that are not linked to an I/O device Entries in the data areas of drive and encoder objects that are enabled (Enable = True) but are not linked to the I/O drive object result in a warning in the error log window. If the link for a function used at runtime is missing, this results in a runtime error. For example, an axis cannot be started if the status word from the I/O drive object is not linked.
