Output Description¶
DONE
Data_Type | Default_Value | Range | Unit |
---|---|---|---|
BOOL | - | - | - |
DONE indicates the processing state of the function block. After completion or abortion of processing due to an error, DONE is set to TRUE for one cycle. This output always has to be considered together with output ERR. If ERR is TRUE, an error occurred. In this case, the error number can be read at output ERNO.
ERR (error)
Data_Type | Default_Value | Range | Unit |
---|---|---|---|
BOOL | - | - | - |
ERR indicates whether an error occurred during the processing of the function block. This output always has to be considered together with output DONE. If DONE is TRUE and ERR is TRUE, an error occurred. In this case, the error number can be read at output ERNO.
ERNO
Data_Type | Default_Value | Range | Unit |
---|---|---|---|
WORD | - | 0 … 65535 | - |
At output ERNO the identifier of an occurred error is provided. It is only valid when DONE and ERR is TRUE, (see, error messages): Error Messages of the Function Block Libraries
MODE
Data_Type | Default_Value | Range | Unit |
---|---|---|---|
BYTE | - | - | - |
Output displays the actual operating mode of the device.
Parameter | Value | Operating mode |
---|---|---|
DC541_MODE_IO | = 16#11 = 17 | IO device (IO mode) |
DC541_MODE_COUNT | = 16#22 = 34 | Counting device (counter mode) |
CYCLE (cycle \ time)
Data_Type | Default_Value | Range | Unit |
---|---|---|---|
WORD | - | - | µs |
Output displays the cycle time of the device. The cycle time is set during the device configuration and can have the following values depending on the channel configuration:
Parameter | Description | Value | |
---|---|---|---|
IO device | 50 µs | ||
Counting device | 1-2 functions | 50 µs | |
3-4 functions | 100 µs | ||
5-8 functions | 200 µs | ||
“Functions” | |||
PWM | Pulse-width modulator | ||
FREQ | Time and frequency measurement | ||
FREQ_OUT | Frequency output | ||
32BIT_CNT | 32 bit counter | ||
FWD_CNT | 32 bit count-up counter | ||
LIMIT | Limit value monitoring for the 32 bit counter |
CFG0…CFG7 (configuration \ of C0…C7)
Data_Type | Default_Value | Range | Unit |
---|---|---|---|
BYTE | - | - | - |
The outputs display the current channel configuration of the channels C0…C7.
CFGx | Channel | Function |
---|---|---|
0 | 0…7 | Normal input |
1 | 0…7 | Normal output |
255 | 0…7 | Interrupt input |
CFGx | Channel | Function |
---|---|---|
0 | 0…7 | Normal input |
1 | 0…7 | Normal output |
2 | 0…7 | Pulse-width modulator (PWM) |
3 | 0…1 | 50 kHz count-up counter (FWD_CNT) |
3 | 2…7 | 5 kHz count-up counter (FWD_CNT) |
4 | 0…7 | Time and frequency measurement (FREQ) |
5 | 4…7 | Limit values for 32 bit counter (LIMIT) |
6 | 0 | Bidirectional 32 bit counter (uses channels 0…3). The channels CFG1…CFG3 can be set as desired. |
7 | 0…7 | Frequency output |
