GFK-1115 Chapter 4 Configuring Communication with the PLC 4 - 7

PLC Network Parameter Definitions
In addition to the unique information that must be supplied for each defined connection,
information must be provided concerning the Genius bus itself. From any PLC Node Parameter
Definition window, you can access the PLC Network Parameter Definition window by pressing
the F1 function key.
Note
In many instances, the default settings indicated in the window will suffice.
Those parameters indicated with an * must correspond to the configuration of
the PLC interface at the other end.
❏ Baud Rate*
The baud rate of the Genius bus can be specified via PCS whenever mode switch setting
5 or 7 is selected. The following can be selected to specify the baud rate for mode switch
settings 5 and 7.
----------------------------- use system default (153.6 kBaud standard)
153.6 kBaud standard
153.6 kBaud extended
76.8 kBaud
38.4 kBaud
If mode switch settings 1 — 4 are used, this parameter is ignored.
❏ Broadcast control data length
Defines the number of bytes that are to be broadcast as global data. This parameter can
range between 0 and 128, inclusive. Note that other devices on the Genius bus must be
configured as to how much global data they will accept from any other device, including
a PANELWARE C400 Controller. Data can be lost if they are configured to accept less
than is being transmitted. To minimize the impact on the scan time of the Genius bus,
this value should be set no higher than the actual amount of global data you need to
broadcast.
