Master diagnostics
All information available for the master is listed in the "Master Diagnostics" section under the [Status] menu item.
The IEC project additionally offers quick diagnostics of the ESM state of the stations. The following table shows the possible states of the master in the network:
Master | ESM state | Description |
|---|---|---|
| Operational | System without faults. |
| Pre-operational | After PLC reset. |
| Operational | The length of the configured process data differs from the hardware setup; at least one slave is not in "operational" ESM state. |
| Init | Deviation between the number of projected devices and hardware setup. |
