DeviceEnable
These bits enable nodes on the PROFIBUS network for data exchange.
Each bit represents a node. When the specific bit is set ‘1’ then the
device (if configured) will exchange data with the PLX51-PBM and when
the bit is off ‘0’ the device does exchange data with the PLX51-PBM.
Bit 0
– Node 0 is enabled for data exchange
Bit 1
– Node 1 is enabled for data exchange
Bit 126
– Node 126 is enabled for data exchange
The user will be able to see if there are any faults (e.g. configured device not found)
by viewing the LEDs of the PLX51-PBM (see the
Diagnostics
section for more
details), by going online with the module in the PLX50 Configuration Utility and
viewing the PLX51-PBM Master and Device Diagnostics, or by viewing the input
assembly of the PLX51-PBM in Logix.
