Value	Definition
0x00	Disable Network ESD
0x01	Enable Network ESD
DO_ESD_Chan can’t be written directly via the DeviceNet network, it is Read-Only. The attribute
Enable_Broadcast_ESD_Ctrl defines if a device is part of the broadcast ESD control scheme from Bit-
Strobe Connection or not. The resulting DO_ESD_Chan is defined in the following table.
The MX allows the standard I/O connection to assert ESD, or the broadcast bit strobe connection to		23
assert ESD.
