Process image

In the process image, the supply voltage outputs and EtherCAT ports are labeled "Channel 1" to "Channel 4". The following table shows the assignment between the designations in the process image and the connection designations:

Designation in the process image	Supply voltage output	EtherCAT port
Channel 1	X60	X40
Channel 2	X61	X41
Channel 3	X62	X42
Channel 4	X63	X43

DPO Inputs Channel 1 to 4

Status bits of the individual channels.

Process image 2:

Error Us: U_S was switched off due to overload.

Error Up: U_P was switched off due to overload.

Warning Us: The output current US currently exceeds the nominal current (CoE parameter 80n0:12).
If the overcurrent persists, U_S is switched off on this channel.

Warning Up: The output current U_S currently exceeds the nominal current (CoE parameter 80n0:13).
If the overcurrent persists, U_P is switched off on this channel.

Status Us: Switching status (on/off) of the output voltage U_S.

Status Up: Switching status (on/off) of the output voltage U_P.

Channel Error: "Error U_S" or "Error U_P" is TRUE.

Error Sum Current: The channel was switched off due to sum overcurrent.

Warning Sum Current: The sum current I_S + I_P of the channel currently exceeds the nominal sum current (CoE parameter 80n0:14).
If the overcurrent persists, the channel is switched off.

Current Us, Current Up: 16-bit measured values of the current output currents.

DPO Inputs Device

Status bits for the entire device.

Process image 3:

Temperature Warning: The internal temperature exceeds the warning threshold.

Temperature Error: The internal temperature has exceeded the error threshold. The output channels have been switched off.

U_S Warning, U_P Warning: Undervoltage warning. The respective input voltage is currently below the warning threshold value U_warn.

Us Error, Up Error: Undervoltage switch-off. The respective input voltage has fallen below the error threshold value U_err.
The output voltages have been switched off.

Global Error Bit: There is at least one error message.

Sum Current Warning: The input sum current I_S + I_P currently exceeds the nominal sum current (CoE parameter F80E:12).
If the overcurrent persists, all channels are switched off.

Error Sum Current: All output voltages were switched off due to sum overcurrent.

Current Us: Current U_S input current at supply voltage input X70.

Current Up: Current U_P input current at supply voltage input X70.

Voltage Us: Current value of the supply voltage U_S in 1/10V

Voltage Up: Current value of the supply voltage U_P in 1/10V

Temperature: Current internal temperature of the device.

DPO Outputs Channel 1 to 4

Output data for the individual channels.

Process image 4:

Output U_S, Output U_P: Switches the respective output voltage on or off.

Reset U_S, Reset U_P: Reset the error state of the respective output voltage.

DPO Outputs Device

Output data for the entire device.

Process image 5:

Enable Control Via Fieldbus:

TRUE: Enables the switching of the output voltages via the output variables "Output Us" and "Output Up".
FALSE: Enables the automatic switching on of the output voltages according to the CoE parameters 80n0:02 and 80n0:03.

Global Reset: Reset the error state of the device and all channels.
