8.4.5 Diagnostics
The VS18/VS26 CANopen slave has a diagnostic attribute to inform a master of its current
state. With this attribute it is possible to monitor the state of the +24V valve power. This can be
achieved by using the CANopen SDO Object Dictionary: Index 0x2102, Sub_Index0. This
message will return 1 byte of read only data, with value 0x01 indicating that the valve power is
present or 0x00 indicating that the valve power is not present.
