7.1 Introduction
The MMC DeviceNet
™
scanner module is an interface between the MMC
and a DeviceNet network. The module contains an on-board processor, a
DeviceNet compliant interface, and firmware that makes it act as the master
to all other nodes on the network.
Prior to initial operation, a file is generated with specific configuration
software in an external PC. This file must be downloaded via the RS232
configuration port to the DeviceNet module prior to initial operation. Two
indicator LEDs (IN/OUT) are connected to this configuration port.
Directly above the DeviceNet port are two LEDs that provide operation
information: Network Status and DeviceNet Scanner Status.
The DIAG LED goes on briefly while the diagnostic tests are running.
