Function
A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Returns active errors and alarms on the controller in two arrays of hundred Booleans.
Every index in the array corresponds to the error and alarm numbers in the tables. See AKD PDMM, PCMM, and PCMM2G Errors and Alarms for a list of errors and alarms that may be generated.
Arguments
Input
| EN | BOOL | Enable |
| ActiveError | BOOL[100] | Array of bool with the size equal to 100 |
| ActiveAlarm | BOOL[100] | Array of bool with size equal to 100 |
Output
| OK | BOOL | |
| Q | DINT | Status of the execution |
Status meaning:
| Bit 0 | Value 0 | No error, no alarm, no shut down |
| Bit 0 | Value 1 | There is an active error or an active alarm (i.e. there is something in the array ActiveError/ActiveAlarm) |
| Bit 1 | Value 0 | No shut down |
| Bit 1 | Value 1 | The PLC "Programmable Logic Controller"
A Programmable Logic Controller, PLC, or Programmable Controller is a digital computer used for automation of industrial processes, such as control of machinery on factory assembly lines.
Used to synchronize the flow of inputs from (physical) sensors and events with the flow of outputs to actuators and events processes will be shut down. This will start 10 seconds after the error is triggered |
| Bit 2-15 | Value 2 | 4 | 9 to 2147483648 | reserved |
