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.
