Remote Relay Control
From PAS, you can send a command to any relay in your device or release a latched
relay, except of the relays that are linked to the internal pulse source. Such relays
cannot be operated outside of the device.
To enter the Remote Relay Control dialog, check the On-line
button on the PAS
toolbar, select Device Control from the Monitor menu, and then click on the Remote
Relay Control tab.
To send a remote command to the relay:
1. From the “Relay Command” box for the relay, select the desired
command.
2. Click on Send.
The dialog shows you the present relay status and whether it is latched by a remote
command or locally from the setpoint.
Device Event Flags
The SA300 has 16 common event flags that are intended for use as temporary event
storage and can be tested and operated from the control setpoints. You can transfer
an event to the setpoint and trigger its operation remotely by changing the event
status through PAS.
To enter the Event Flags dialog, check the On-line button on the PAS toolbar, select
Device Control from the Monitor menu, and then click on the Event Flags tab.
