8 MMC Profibus Option Module
8.1 Introduction
The MMC Profibus scanner module is an interface between the MMC and a
Profibus network. The module contains an on-board processor, a Profibus
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 Profibus module prior to initial operation. Two
indicator LEDs (IN/OUT) are connected to this configuration port.
Directly above the Profibus port are two LEDs that provide operation
information: Network Status and Profibus Scanner Status.
The DIAG LED goes on briefly while the diagnostic tests are running.
