Command Block List
The following command blocks are supported by the gateway:
Block Range Mode Direction Description
100 and 101 Command Request
without Response
Node to ProLinx Event Data
200 and 201 Command Request
without Response
Node to ProLinx Set Time
200 and 201 Command Request
with Response
ProLinx to Node Get Time
202 and 203 Command Request
with Response
ProLinx to Node Get Event Buffer Counts
Two block IDs per command type are required to allow the detection of a new
block. So the remote node can switch between two block IDs when a new
command block for the same type is requested. Even if the block only contains a
request with response type, then offsets 0 and 99 must also trigger to a new
value to allow the gateway to detect a new block.
The following general examples illustrate the block transfer mechanism.
For these examples, set the DB Input Window Start parameter to 3000 and set
the DB Output Window Start parameter to 3100.
