10.1.4.5 Remote control
One instance with 3 elements of 16 bits is reserved for remote control of the
release, accessed via object: 0xA2, with attribute: 5 and Instance: 358.
These three elements should be written together with a “slave action code”
and the corresponding ones’ complement.
The data format registers, which is an array of 16 bits, are shown below.
Data format for remote control
Instance 358 - Element 1
Instance 358 - Element 2
Instance 358 - Element 3
The “slave action code” and its functioning are listed in
table 56, and
whether it is supported depends on the specific product.
If the “slave action code” and the associated ones’ complement command
are valid, the release will perform the action in question. If the “slave action
code” and the associated ones’ complement command are invalid, the
exception code can be queried by requesting the Modbus communication
status of the ECAM from the controller via a dedicated industrial protocol
object (via object: 0xA2, with attribute: 5 and instance: 410).
