Differences from the M/N 57C442 Module Interface
If you are modifying an existing application for the 57C442 Data
Highway Plus module to work on the ControlNet module, you should be
aware of the following differences between the interface on the two
modules.
• There is no global data on ControlNet.
• There are fewer integer files on the ControlNet module. The
ControlNet module has three integer files (N7-N9). The Data
Highway Plus module has twelve (N7-N18).
• There is no DH+ active node list on the ControlNet module. Use the
ControlNet active node list instead.
• The ControlNet module doesn't accept unsolicited PCCC diagnostic
commands.
• You don't have to explicitly put the ControlNet module online.
• You don't have to set the message timeout; the ControlNet module
sets it based on network parameters.
• The ControlNet module doesn’t support DH+ diagnostic counters
(use the ControlNet counters instead).
• The ControlNet module doesn’t support the DH+ station name.
