Configuration of the CM574-RS in the AC500 CPU Project¶
To append a Communication Module, add the Communication Module to the Extension_Bus node.
- Right-click the desired Slot and select Add object.
- Select the Communication Module from the list and click
Replace object. - Double-click on CM574_RS (CM574-RS) to open the CM574-RS Configuration.
The following parameters are available:
| Parameter | Default value | Value | Meaning |
|---|---|---|---|
| Run config fault | No | No | The user program is not started in case of a configuration error. |
| Yes | The user program is started independent of a faulty configuration of the CM574. | ||
| Max. wait run | 3000 | 0…120000 | Max wait time for valid inputs. |
| Min. update time | 10 | 10…2000 | Minimum update time of the in- and outputs in [ms]. |
| Enable debug | On | Off | The user program of the CPU only runs if the Communication Module is in RUN mode. The user program of the Communication Module only runs when the CPU is in RUN mode. Debug commands on the Communication Module are not permitted. |
| On | The user program of the CPU runs independent of the Communication Module status, i.e., all debug commands are permitted on the Communication Module. | ||
| Watchdog | 400 | 400..60000 | Watchdog in [ms] |
Basically 2 different modes can be configured at the sub modules of the CM574-RS Communication Module. Either cyclic data exchange (default setting) or remotely controlled COM port usage is available.
