Monitoring Digital I/O, and Changing Output Status and Parameters

While the

MicroSmart

is communicating with AS-Interface slaves through the AS-Interface bus, operating status of AS-

Interface slaves can be monitored using

WindLDR

on a computer. Output statuses and parameter image (PI) of slaves con-

nected to the AS-Interface master module can also be changed using

WindLDR

.

1. From the WindLDR menu bar, select Online > Monitor. From the WindLDR menu bar, select Online, and select

Monitor AS-Interface Slaves in the pull-down menu. The Monitor AS-Interface Slaves dialog box appears.

Active slaves are indicated with blue shade.

Next step is to change output status of the active slave.

2. Click the output of slave address 01 to open the Slave Status 01A dialog box.

3. Click the On or Off button to change the statuses of outputs O0 through O3 and parameters (PI) P0 through P3 as

required.

The selected parameters (PI) are in effect until the CPU module is shut down. When the CPU module is powered up again,
the parameter values (PP) selected in the slave configuration procedure (page 28-10) will take effect. To store the changed
parameter values to the AS-Interface master module EEPROM, execute the Copy PI to PP command by storing 0306,
0100, 0000, 0000, 0001 to data registers D1941 through D1945. See page 28-28.
