Table 11: Profibus LED indications
When used for Profibus, the Fieldbus port has the following characteristics.
•
Baud rate: 9600, 19200, 31250, 45450, 93750, 187500, 500000, and 1.5M bps (auto-
detect) *
•
Address: 1 to 126
•
Vendor ID: 4D20 (hex)
•
Data table size: inputs = 174 bytes, outputs = 2 bytes
•
To be actioned, output bit must be 1 for a minimum time of 100 ms.
* Profibus communications will operate only in 1.5Mbps or auto-detect with the present
implementation. Auto-detect includes baud rates 19.2 kbps, 187.5 kbps, 500 kbps, and 1.5
Mbps.
The Profibus DP Master must read the GSE (Device Master Data) file of the MM300 for the
purposes of configuration and parameterization. The GSE file for the MM300 is named
GEMU4D20.gse.
Profibus power supply
configuration
The Profibus port has two modes of powering the electronics: internal or external. In
internal mode, a local 5 V is used, so no external voltage is required (pin 1 and pin 5 of the
connector). In external mode, the user must supply an external bus voltage on pin1 and
pin 5 of the connector. Profibus is shipped from the factory configured for internal mode.
Use the figures below to configure the the comms board power supply.
