Command and Frequency Control Selections
The user may select only one Command source and only one source for Frequency control. The default settings for Command and Frequency control are Use Control Terminal Strip and Use RR, respectively.
The G7 ASD has a command register for each item listed as a Command or Frequency source. The registers store the Override setting for each control source. The registers are continuously scanned to determine if any of the listed items are in the Override mode.
For each scan cycle, the command registers of the control sources are scanned for the Override setting in the order that they are listed in Table 5. The first item of the Command section and the first item of the Frequency section detected as being in the Override mode will be used for Command and Frequency control, respectively. If no items are detected as being in the Override mode, the settings of F003 and F004 will be used for Command and Frequency control, respectively.
Any or all of the Command and Frequency control input sources may be placed in the Override mode.
Placing the G7 ASD in the Local mode (Local/Remote LED on) via the EOI places the RS232/RS485 or the Common Serial (TTL) control selections in the Override mode for Command and Frequency input (see the section titled Override Operation below for the proper setting). The Local/Remote control Override feature for Command and Frequency (or either) may be enabled/disabled at Program

Communications may be used to place the remaining Command and eligible Frequency control input sources in the Override mode. Once placed in the Override mode this setting is valid until it is cancelled, the power supply is turned off, or the unit is reset.
