The six digital inputs of the module can be found under DIG inputs 1 to 6.
• Input 1 - socket 0, pin 4
• Input 2 - socket 0, pin 2
• Input 3 - socket 1, pin 4
• Input 4 - socket 1, pin 2
• Input 5 - socket 2, pin 4
• Input 6 - socket 3, pin 4
The four pressure measuring inputs of the module can be found under AI
inputs Channel 1 to 4.
• Underrange: the pressure has fallen below the underrange value
• Overrange: the pressure has exceeded the overrange value
• Limit1: the Limit1 value specified in the CoE objects was reached
• Limit2: the Limit2 value specified in the CoE objects was reached
• Error: one of the above events has occurred
• Value: the measured pressure value in the unit pre-scaled in the CoE
objects (e.g. mbar)
The diagnostic data for the module can be found under DEV Inputs Device.
• Safe State Active: there was an interruption in communication, causing the
outputs to change to the safe state
• Sync error: a synchronization error has occurred
• Undervoltage Us: the voltage Us is less than approx. 18 V
• Undervoltage Up: the voltage Up is less than approx. 18 V
• TxPDO Toggle: EtherCAT variable for displaying a transmitted date of
receipt (see general EtherCAT documentation)
The two digital outputs of the module can be found under DIG outputs 1 and
2.
• Output 1 - socket 2, pin 2
• Output 2 - socket 3, pin 2
