Preselection of process data

The EL2212 can be operated with different types of function.

PDOs can be preselected with the System Manager by “Predefined PDO Assignment” on the “Process Data” tab.

Standard digital output with InfoData

The outputs can be written directly with this standard PDO assignment, i.e. the connected actuators can be switched directly.
If the option "with InfoData" is selected, the synchronous information data are also automatically shown.

Preselection of process data 1: — Standard PDO assignment

Name of the process input data	Description / function
Ready to activate	The terminal signals its readiness for operation here.
Output active	The output is actively switched.
Tristate active	The output drivers are switched to tristate.
PWM active	The PWM is actively switched to the output n.
Warning	A warning has occurred - > evaluate “Diag data” (index 0xA000).
Error	An error has occurred and the output drivers are deactivated - > evaluate “Diag data” (index 0xA000).
TxPDO Toggle	Changes its state each time process data are exchanged.
WcState	Each datagram of the EL2212 indicates its processing state here. This allows the EL2212 to be monitored for correct process data communication.
InfoData (State)	Status display of the “EtherCAT state machine”

Name of the process output data	Description / function
Output	Activate the output of channel n
Tristate	Switch channel n to high resistance
PWM	Activate PWM at the output of channel n
Reset	Reset of an error on channel n

	Observe priorities If the two signals “Output” and “Tristate” are activated at the same time, “Tristate” has a higher priority.

DC digital output / with InfoData

In addition to the standard signals, the PDOs “DC feedback” and “DC Sync” are activated in this assignment.

If the option "with InfoData" is selected, the synchronous information data are also automatically shown.

Preselection of process data 3: — PDO assignment with activated DC

Name of the process input data	Description / function
Feedback	The terminal returns the states of the input signals in this byte. Bit 0: Output channel 1 Bit 1: Tristate channel 1 Bit 2: Output channel 2 Bit 3: Tristate channel 2

Name of the process output data	Description / function
Activate	This byte activates a new start time in the terminal through the transition 0 → 3
Start time	64-bit value of the next desired switching event.

Synchron information data (PDO 0x1A01 or 0x1A03)

Additional information can be displayed with the PDO 0x1A01 (Ch.1) or 0x1A03 (Ch.2).
The PDO assignment must be manually activated with the “Synchon information data”.

Two further data words are displayed per channel for more exact information about the states of the actuators or the driver stage. These are to be configured via the appropriate index in the CoE.
Among other things, the interior temperature of the terminal or the momentary current through the connected actuator can be selected, for example.

Preselection of process data 4: — Activated “Synchron Info data”

Name of the process input data	Description / function
Info data 1	Additional channel information
Info data 2	Additional channel information

Multi-time stamping 2 Ch. 10x/5x/2x/1x

The multi-time stamping supports two channels, each with 1-fold, 2-fold, 5-fold or 10-fold oversampling.

Preselection of process data 5: — Activated "multi-time stamping" 2 Ch. 2x

Name of the process input data	Description / function
Output short circuit	Output has a short-circuit/overload.
Output buffer overflow	More events have been written into the buffer than the number of free elements available.
Output state	Current state of the output.
Input cycle counter	Update counter of the PLC input data.
Output order feedback	Feedback of the order counter.
Events in output buffer	Current number of events remaining in the buffer.

Name of the process output data	Description / function
Output buffer reset	Clear all events in the output buffer.
Manual output state	Set the output permanently to this value (can be activated via CoE and PDO, see Enable manual operation).
Force order	Already expired events are also output.
Enable manual operation	Allow manual operation via the PDO bit "Manual output state".
Output order counter	Incrementation of this value indicates to the terminal that there are new values in the PDO.
No of output events	Number of events deposited in the PDO
Output event state n	Output value at the time of the n^th time stamp
Output event time n	Time stamp of the n^th event
