Power Up; Changing Parameters During Operation - ProSoft Technology MVI56-PNPM User Manual

MVI56-PNPM ♦ ControlLogix Platform
Phantom Network Protocol Master Communication Module
Refer to the Installing and Configuring the Module section for a description of the
configuration of the module. The MVI56-PNPM module must be configured at
least once when the card is first powered, and any time thereafter when the
parameters must be changed.

2.1.1 Power Up

On power up, the module enters into a logical loop waiting to receive
configuration data from the processor. Upon receipt, the module will begin
execution of the command list if it is present.

2.1.2 Changing Parameters During Operation

A copy of the module's configuration data is mapped in the module's database as
displayed in the table above. These values are initialized when the module first
receives its configuration from the ControlLogix processor. Any node on the
network can change this data. A master port on the module may poll a slave for
the data or a slave port could receive the data from a remote master unit. The
module will not use this data until it is commanded. Ladder logic can be written to
issue a Write Configuration command block (9997) to the module. A remote
device can set a value of 9997 at address 6800 in the module to download the
configuration to the processor. Alternatively, the configuration/debug port on the
module can be used to issue the command directly to the module. All three of
these methods will force the module to download the configuration to the
ControlLogix processor. Ladder logic must exist in the processor to accept the
blocks sent by the module. If everything is configured correctly, the module can
receive its configuration from a remote device.
