Supplementary Example
Using the Backplane
These supplementary examples demonstrate how to use the
backplane to operate the interface module’s Real Time Clock and Data
Echo features.
Real Time Clock
You can use the interface module as a Real Time Clock (RTC) in
conjunction with normal module operation. This example shows you
how to set up the Calendar/Clock Function using the backplane.
Parameter Settings
The values used by the RTC are in N10:1-7, and are initialized as
shown in the table below.
Parameter Settings
User Program
The example program shown on the following page initializes the
interface module’s calendar and RTC when bit B3:0/0 is toggled from
low to high. Bit B3:0/1 is toggled every 2.56 seconds, and the new
RTC values that are read are then placed in data file N10:11-17.
IMPORTANT
Before you begin these applications, be sure that the
JW4 jumper is in vertical Run mode (module
configuration ID=3509).
