Timestamp for the stored position value
 | Note on using the timestamp function To be able to use the timestamp function, the EL5072 must be operated in "DC Latch active" mode (setting via the "DC" tab, see chapter "Operation mode - Synchronization". |
The timestamp is made possible by the distributed clocks technology in the EtherCAT system. This local clock can be used to synchronize the data acquisition.
The EL5072 provides a timestamp on the stored position value.
The terminal provides the timestamp with an extent of 64 bits. The timestamps are contained in the following "Predefined PDO Assignment":
Predefined PDO Assignment |
|---|
1. Ch. Standard, Timestamp |
2. Ch. Standard, Timestamp |
They can be selected or deselected as optional PDOs.
PDO Assignment | Name | Description |
|---|---|---|
IND Latch Timestamp Channel 1 | Contains timestamps in the 64 bit range for channel 1 | |
IND Latch Timestamp Channel 2 | Contains timestamps in the 64 bit range for channel 2 |
Timestamp on the stored position value
The process data index 0x60n2:01 "Latch event Timestamp" indicates the timestamp of the position value that was stored via the last positive edge of digital input.
Parameterization of the Latch input | 0x60n2:01 "Latch event Timestamp" | |
|---|---|---|
0x70n0:03 | Enable Latch on digital input | the last rising edge at the digital input at which the counter value was stored in index 0x60n1:02 "Latch value" |
