CONFIGURING COMMUNICATIONS
MAPPING DATA
This will typically produce slightly reduced performance, as Crimson will poll each device in
turn, rather than talking to both devices at the same time. It will, however, conserve Ethernet
protocols, allowing more complex applications without running out of resources.
MAPPING DATA
Having configured the protocol, you must now decide what range of addresses you want to
utilize in the target device. In this example, we want the Master to read and write module data
to an Allen Bradley PLC via DF1. We begin by selecting the device icon in the left-hand pane
of the Communications window, and clicking the Add Gateway Block button in the righthand
pane. An icon to represent Block 1 will appear, and selecting it will show the following
settings…
In the example above, we have configured the Start Address to N010:0000 to indicate that
this is where we want the block to begin, with a size of 16, which indicates how many
registers we want to map data to. Finally, we have configured the Direction property as MC to
Device, to indicate that we want the Modular Controller to write module data into these
registers.
