Module configuration is accomplished through a text configuration file loaded
from the module's Compact Flash disk.
Port 1 on the module connects to a DNP master unit. Port 2 can be attached to a
DNP master or slave unit. These ports can be configured for an RS-232, RS-422
or RS-485 interface by setting the jumper on the port to the appropriate position.
This defines the physical connection. Port 2 can be configured to utilize a dial-up
modem if the port is configured as a slave.
You must also define the communication parameters and the DNP parameters.
This includes parameters such as Baud Rate, RTS delays, timeouts, retry counts
and modes of protocol operation.
2.1 Quick Start Guide
This section describes the installation of the MVI46-DNP module in an SLC rack
and also provides information on installing and configuring the module.
1 Set the jumpers (page 9) on Port 1 and Port 2 for the correct communication
interface (RS-232, RS-422 or RS-485). Each port is configured separately.
2
Turn off power to the SLC rack and install the module.
3
Turn on the power to the rack.
CAUTION: Installing the module into a SLC may cause the processor to fault and may
cause incorrect operation of the current program loaded in the SLC. This operation
must be performed by a qualified person familiar with the SLC program and module.
The fault condition can be cleared after the correct program and the data tables have
been configured in the SLC.
4 Configure the SLC for the module. Starting with the sample ladder logic
provided with the module, complete the following steps.
