6.8.3 Object 0x5E44: Digital output value
The <DigitalOutputValue> (0x5E44) shows the state of the digital outputs.
6.9 Local CAN
The servo valve has a local CAN connector X2 or X10 which can be used to
• connect the Moog Valve and Pump Configuration Software to the servo valve.
• connect an external CAN device to the servo valve e.g. a position sensor or a pressure transducer.
The following CAN protocols are supported:
• Process data object (PDO) protocol
Chapter "6.9.2 Local CAN process data object (PDO)", page 105
• Service data object (SDO) communication
The SDO communication will be handled by (vendor specific) parameters. With these parameters, a
gateway between the field bus and the local CANs SDO channel is realized.
Chapter "6.9.6 Local CAN service data object (SDO) gateway", page 119
• Network management (NMT) protocol
The NMT protocol command "start remote node" is supported.
Chapter "6.9.1.3 Object 0x5B02: Start remote node", page 104
• Synchronization (SYNC) producer protocol (implemented indirectly)
If a synchronous transition is needed, a SYNC-telegram can be emulated using one of the transmit PDO
channels.
Chapter "6.9.7 Local CAN Synchronization (SYNC) producer protocol emulation", page 121

If one application parameter is written by the local CAN interface and the field bus by the same cy-
cle, the parameter last written will be processed.
